Description

    FIELD OF THE INVENTION
  • The present invention relates to a building construction.
    • BACKGROUND OF THE INVENTION
  • Modern wall surfaces, roofs, and similar surface constructions of buildings such as domestic houses are mostly made with an internal support construction and a covering forming an external surface of the building. The external surface is typically supposed to give the building an aesthetic appearance and typically to prevent ingress of water or other contaminants from entering the support construction. The support construction is supposed to carry the surface.
  • Between the support construction and the covering, it is typical to arrange a membrane forming a wind and vapour barrier. The membrane is typically a cloth of fabric or plastic material suspended directly on the support construction or suspended on panels between the support construction and the covering.
  • The covering could be tiles or other materials suitable for the building construction in question.
    • SUMMARY OF THE INVENTION
  • It is an object of embodiments of the invention to provide an improved building construction and particularly to improve the protective barrier between the support construction and the covering and to ensure improved ventilation in a space there between.
  • For these and other objects the disclosure, in a first aspect provides a building construction comprising a load bearing support construction and a covering. At least one underlayment profile extends in a longitudinal direction.
  • Thus, according to a first aspect, the disclosure provides a building construction comprising a load bearing support construction, at least one underlayment profile extending in a longitudinal direction, and a covering forming an external surface, wherein the underlayment profile defines a plateau fixed to the support construction and defining a barrier between an outer space between the covering and the underlayment profile and an inner space between the underlayment profile and the support construction, wherein the underlayment profile further comprises a suspension flange extending in the longitudinal direction and connecting the covering and the plateau, whereby the underlayment profile joins the load bearing support construction and the covering.
  • The building construction comprises a load bearing support construction which may be a wooden construction, i.e., a construction primarily made of wooden elements. The support construction may alternatively be made of another material, such as metal or plastic. The support construction may be made of a combination of different materials. The building construction may as an example be a roof or a wall.
  • The building construction comprises a covering forming an external surface of the building constructions. As an example, the covering may comprise tiles, roof panels, and/or fagade panels. The covering may be made of clay, fibre cement, plastic, metal, etc.
  • The building construction comprises at least one underlayment profile extending in a longitudinal direction and defining a barrier between an outer space between the covering and the underlayment profile and an inner space between the underlayment profile and the support construction. The underlayment profile defines a plateau fixed to the support construction, where the plateau may be a substantially flat part which may comprise protrusions and/or indentations. The underlayment profile further comprises a suspension flange extending in the longitudinal direction. The underlayment profile may be an elongated element extending in the longitudinal direction; i.e., an element where the largest dimension of the element is in the longitudinal direction.
  • The suspension flange connects the covering and the plateau, whereby the underlayment profile joins the load bearing support construction and the covering. The suspension flange may have a shape matching a part of the covering which may at least partly lock the covering to the underlayment profile, whereby the underlayment profile may have the function of a batten.
  • The underlayment profile may as an example be made of metal, such as steel or made of a plastic material, such a polyvinyl chloride (PVC). Consequently, the underlayment profile may be a substantially self-supporting element, where bending of the profile may be avoided or at least reduced, even for an underlayment profile having an elongated shape.
  • The building construction may comprise a plurality of underlayment profile which may be arranged in a row, where each of the underlayment profiles may extend in the longitudinal direction and may be fixed to the support construction. The underlayment profiles may be offset relative to each other at an underlayment-profile-distance in a transverse direction, where the transverse direction may be substantially perpendicular to the longitudinal direction. The underlayment-profile-distance may be such that the plateau of each underlayment profile overlaps the plateau(s) of adjacent underlayment profile(s), whereby the overlapping plateaus define a barrier between the outer space and the inner space. The overlap may as an example be in the range of 5-50 mm.
  • One of the plurality of underlayment profiles may define a lower bordering underlayment profile which terminates the row of underlayment profiles in one direction. Another one of the plurality of underlayment profiles may define an upper bordering underlayment profile which terminates the row of underlayment profiles in another direction. In an embodiment comprising more than two underlayment profiles, the remaining of the plurality of underlayment profiles may define intermediate underlayment profiles in the row of underlayment profiles, i.e., intermediate underlayment profiles being arranged between the lower bordering underlayment profile and the upper bordering underlayment profile.
  • If the building construction is a roof, the upper bordering underlayment profile may be arranged closer to the ridge, whereas the lower bordering underlayment profile may be arranged closer to the eaves. The longitudinal direction may be a direction along the ridge. If the building construction is a fagade, the upper bordering underlayment profile may be arranged closer to the top of the fagade, whereas the lower bordering underlayment profile may be arranged closer to the bottom of the fagade. The longitudinal direction may be a direction along the fagade.
  • The underlayment profile may further comprise a fixation flange for fixating the underlayment profile to the support construction. The fixation flange may be joined to the plateau along a first edge of the plateau and may extend in the longitudinal direction. The fixation flange may extend along the full length of the plateau or along a part of the plateau. In an embodiment without a fixation flange, the underlayment profile may be joined to the support construction at the plateau.
  • The fixation flange may define a portion with a component extending in a direction perpendicular to the longitudinal direction and transverse direction. In a specific embodiment, the portion itself may extend in a direction perpendicular to the longitudinal direction and transverse direction. Due to this portion, the plateau may be arranged at a distance to the support construction, when fixed to the support construction. This may allow for ventilation of the inner space of the building construction along the support construction.
  • Additionally, the fixation flange may strengthen the plateau against deflection transverse to the longitudinal and transverse directions, as the fixation flange may reduce bending of the plateau, when being joined to the plateau along the first edge and extending in the longitudinal direction.
  • The suspension flange may be joined to the plateau along a second edge of the plateau. The first edge and the second edge may extend substantially in parallel along opposite edges of the plateau.
  • In one embodiment, the plateau, the fixation flange, and the suspension flange may be made in one piece from a sheet of a plate shaped material. At least one of the first and second edges may be constituted by a folded part of the plate shaped material. In an alternative embodiment, the fixation flange, and the suspension flange may be made in one piece in a moulding process.
  • In a further alternative, the fixation flange and the plateau are made as two individual and separable components. The suspension flange may likewise be made as an individual component which may subsequently be attached to the plateau along the second edge.
  • The plateau may comprise a plane portion defining more than 50 pct of the plateau. The non-plane part may comprise one or more protrusions and/or indentations. The non-plane part may however, except for the protrusion(s)/indentation(s) be substantially plane.
  • A fixation rim may be joined to the fixation flange along a fixation edge. In one embodiment, the fixation flange defines a portion with a component extending in a direction perpendicular to the longitudinal direction and transverse direction, where one upper edge of the portion may be joined to the plateau along the first edge. The fixation rim may be joined to an opposite lower edge of the portion; i.e., the fixation edge. The fixation rim may be joined to the fixation flange along the fixation edge (lower edge) at an angle in the range of 90 degrees +/- 30 degrees, thereby forming a substantially L-shaped fixation element.
  • The fixation rim may be fixed to the support construction by fixation means. The fixation means may as an example be screws, nails, rivets, glue, or other similar.
  • To provide a continuous barrier between the outer space and the inner space, the covering may be fixed to the suspension flange without penetrating the plateau. This may as an example be achieved by a suspension flange extending in an outwards direction away from the support construction allowing the covering to hang on the suspension flange.
  • In one embodiment, the fixation flange may extend from the plateau in an inward direction towards the support construction, whereas the suspension flange may extend from the plateau in an outwards direction away from the support construction. The latter may allow for suspension of the covering on the suspension flanges, whereas a fixation flange extending in an inward direction may provide a distance between the plateau and the support construction which may allow for ventilation of the inner space between the underlayment profile and the support construction.
  • To facilitate fixing of the underlayment profile, the support construction may comprise at least two beams extending in a transverse direction, where the transverse direction is a direction transverse to the longitudinal direction in which the underlayment profile extends. The transverse direction may be substantially perpendicular to the longitudinal direction. The beams may be offset relative to each other at a beam-distance in the longitudinal direction. The number of beams may depend on the length of the building construction in the longitudinal direction. The beam-distance may be substantially constant along the length of the building construction in the longitudinal direction. The at least one underlayment profile may extend in the longitudinal direction between the at least two beams. An underlayment profile may have a length being larger than the beam-distance, whereby an underlayment profile may extend between two, three, four, or even more beams.
  • In one embodiment, the building construction may form a roof construction, where the beams may be rafters forming a roof, and where the covering may be configured to shed water.
  • The building construction, such as in the form of a roof construction, may comprise a lower bordering support profile extending in the longitudinal direction, which lower bordering support profile may be located between the beams and the lower bordering underlayment profile. The lower bordering support profile may support the lower bordering underlayment profile along the full length of the lower bordering underlayment profile and may provide a distance between the support construction in the form of the beams and the lower underlayment structure.
  • The building construction may further comprise at least one gutter bracket extending through holes in the lower bordering support profile. The gutter bracket(s) may carry a gutter which may extend along the fagade below the roof construction. The lower bordering support profile may comprise a plurality of perforations which may be transformed into holes when inserting a gutter bracket. The perforations allow for a variable distance between two neighbouring gutter brackets, e.g., dependent on the size of the gutter and the gutter brackets.
  • The lower bordering support profile may comprise an upper support flange, a lower support flange, and a connecting flange joining the upper and lower support flanges. The lower bordering support profile may be arranged such that the upper support flange and the lower support flange support the lower bordering underlayment profile against the beams.
  • The gutter bracket(s) may extend through holes in the lower bordering support profile. The gutter bracket(s) may each extend between an outer end and an opposite inner end, where the gutter may be supported by an outer part of the gutter bracket(s), and where the gutter bracket may be attached to the lower bordering support profile, e.g., at the upper support flange.
  • At least one of the upper support flange, the lower support flange, and the connecting flange may comprise a perforated portion. The perforated portion(s) may enable ventilation between two opposite sides of the lower bordering support profile. Perforations may additionally be used for the gutter bracket(s).
  • The building construction, such as in the form of a roof construction, may comprise an upper bordering termination profile defining an elongated termination plateau and a suspension flange joined to the termination plateau along a second edge. The elongated termination plateau may define a barrier between the outer space and the inner space, as the plateau of an underlayment profile. And the suspension flange of the upper bordering termination profile may as the suspension flange of the underlayment profile connect the covering and the plateau.
  • The elongated termination plateau may define a free edge opposite the second edge, where the free edge may terminate adjacent a ridge of the roof. The free edge may be pushed towards the ridge. As the elongated termination plateau terminates in a free edge, it may further be possible to shorten the elongated termination plateau to fit the size of the upper bordering termination profile to the size of the roof, when arranging a plurality of underlayment profiles in a row on the support construction to form a barrier and starting from the lower bordering underlayment profile.
  • The elongated termination plateau may comprise a perforated portion which may allow for ventilation between the inner and the outer space. To minimise the risk of water ingress to the inner space, a plurality of the holes forming the perforated portion may each comprise an outwardly extending collar circumferentially around the holes.
  • The building construction may comprise an upper bordering support profile which may extend in the longitudinal direction and may be located between the beams and the upper bordering termination profile. The upper bordering support may be used for fixating the upper bordering termination profile to the support construction. The upper bordering support profile may extend in the longitudinal direction and may be joined to the termination plateau along a first edge of the termination plateau, e.g., after shorting of the termination plateau, if necessary. Due to upper bordering termination profile, the termination plateau may be arranged at a distance to the support construction.
  • The upper bordering support profile may comprise a perforated portion which may allow for ventilation between opposite sides of the upper bordering support profile. The perforated portion may extend along the full length of the profile in the longitudinal direction. Alternatively, only one or more sections along the length of the profile may comprise a perforated portion.
  • The building construction, such as in the form of a roof construction, may comprise a ridge-profile adjacent to the upper bordering underlayment profile or adjacent to the upper bordering termination profile. In an embodiment without an upper bordering termination profile, the ridge-profile may be arranged adjacent to the upper bordering underlayment profile, whereas the ridge-profile may be arranged adjacent to the upper bordering termination profile in an embodiment comprising an upper bordering termination profile.
  • The ridge-profile may define an elongated ridge plateau, a ridge flange joined to the plateau along a ridge edge extending in the longitudinal direction, and a suspension flange joined to the ridge plateau along a second edge extending in the longitudinal direction, where the second edge and the ridge edge may extend substantially parallel along opposite sides of the ridge plateau. The ridge flange may extend upwards away from the support construction. The suspension flange of the ridge-profile may as the suspension flange of the underlayment profile connect the covering and the plateau.
  • As an alternative to the ridge-profile, the building construction may comprise a double ridge-profile, where the double ridge-profile comprises two ridge-profiles being attached to each other by an upper ridge flange which connects the ridge flange of one ridge-profile with the ridge flange of the other ridge-profile. The double ridge-profile may be made in one piece or may alternatively be made from two or more pieces which are subsequently attached to each other.
  • The building construction may comprise a ridge encapsulation encapsulating the ridge flange. The ridge encapsulation may encapsulate an additional ridge flange to encapsulate a ridge flange from each side of the roof, or may encapsulate the two ridge flanges of the double ridge-profile. The ridge encapsulation may comprise a first encapsulation flange, a second encapsulation flange, and a connecting encapsulation flange joining the first and second encapsulation flanges. When positioned on the building construction, such as on the roof construction, the first and second encapsulation flanges may extend towards the support construction, and the ridge flange may extend into a cavity formed between the first and second encapsulation flanges and the connecting encapsulation flange.
  • The ridge flange may comprise a plurality of protrusions, e.g., in the form of a stamping, which may facilitate positioning of the ridge encapsulation, as a lower edge of the ridge encapsulation may be retained by the protrusion. The ridge encapsulation may comprise a perforated portion allowing for ventilation between opposite sides of the ridge encapsulation.
  • The building construction, such as in the form of a roof construction, may additionally comprise a comb structure with a shaft holding a row of teeth. The comb structure may extend in the longitudinal direction and may be attached to the suspension flange of the lower bordering underlayment profile. The comb structure may extend from the suspension flange towards the covering to limit access to the outer space between the covering and the underlayment profile. The distance between the teeth may be sufficiently small to avoid birds and rodents to enter the outer space via the gaps between the teeth.
  • The plateau may comprise a water trap preventing a free flow of water between an outer surface of the plateau and an inner surface of a plateau of an adjacent underlayment profile. Without the water trap there may be a risk, that water on the outer surface of a plateau may flow upwards due to wind and may flow to the inner surface of an adjacent underlayment profile as the adjacent underlayment profile may overlap the underlayment profile.
  • The water trap may be formed by at least one projected portion extending in an upwards direction away from the support construction. As an example, the water trap may comprise a plurality of V-shaped projection which may be arranged upside down whereby a flow of water may be stop by the V's. A single row of V-shaped projections may be arranged along the longitudinal direction. As an alternative, the water trap may comprise two or more rows of V-shaped projections, where the V's of one row are staggered relative to the V's of another row. The projected portions may be formed by a stamping process. As an alternative or addition, the water trap may comprise an element attached to the plateau.
  • At least one of the fixation flange and the suspension flange may comprise an opening forming a passage for air or water. A plurality of openings may be arranged along the fixation flange and/or the suspension flange in the longitudinal direction to form a passage consisting of a plurality of openings. The passage may form part of a flow path across a plurality of underlayment profiles. This may allow drainage along the plateaus in the outer space from an upper one of the underlayment profiles to a lower one of the underlayment profiles. Additionally, the passage may allow for ventilation along the plateaus.
  • The building construction may comprise an end flange joined to the plateau along a third edge extending in a transverse direction and terminating the plateau longitudinally. The third edge may extend between the first and the second edge of the plateau. A similar end flange may be joined to the plateau along a fourth edge, where the fourth edge terminates the plateau longitudinally opposite to the third edge.
  • According to a second aspect, the disclosure provides an underlayment profile for a building construction comprising an support construction and a covering, wherein the underlayment profile defines an elongated plateau, a fixation flange joined to the plateau along a first edge, and a suspension flange joined to the plateau along a second edge, wherein the fixation flange is configured for fixation to the support construction, and the suspension flange is configured for supporting the covering.
  • It should be understood, that a skilled person would readily recognise that any feature described in combination with the first aspect of the disclosure could also be combined with the second aspect of the disclosure, and vice versa.
  • The underlayment profile according to the second aspect of the disclosure is very suitable for the building construction according to the first aspect of the disclosure. The remarks set forth above in relation to the building construction are therefore equally applicable in relation to the underlayment profile.
  • The plateau may comprise at least one projected portion extending in an upwards direction away from the support construction. The at least one projected portion may act as a water trap, when the underlayment profile is arranged at a building construction.
  • To allow ventilation of a building construction, at least one of the fixation flange and the suspension flange may comprise a perforated portion.
  • According to a third aspect, the disclosure provides a kit of profiles comprising at least one underlayment profile according to the second aspect, and at least one of:
    • a lower bordering support profile comprises an upper support flange, a lower support flange, and a connecting flange joining the upper and lower support flanges,
    • an upper bordering termination profile defining an elongated termination plateau and a suspension flange joined to the termination plateau along a second edge, wherein the elongate termination plateau defines a free edge opposite the second edge,
    • an upper bordering support profile configured to support the upper bordering termination profile in a building construction,
    • a ridge-profile defining an elongated ridge plateau, a ridge flange joined to the plateau along a ridge edge, and a suspension flange joined to the ridge plateau along a second edge, and
    • a ridge encapsulation for encapsulating the ridge flange.
  • It should be understood, that a skilled person would readily recognise that any feature described in combination with the first and second aspects of the disclosure could also be combined with the third aspect of the disclosure, and vice versa. The remarks set forth above in relation to the building construction and the underlayment profile are therefore equally applicable in relation to the kit of profiles.
  • According to a fourth aspect, the disclosure provides a method for making a building construction, the method comprising the steps of:
    • providing a support construction for at least one underlayment profile and a covering,
    • providing at least one underlayment profile with an elongated plateau, a fixation flange joined to the plateau along a first edge, and a suspension flange joined to the plateau along a second edge,
    • providing a covering,

    DETAILED DISCLOSURE OF THE INVENTION Definitions
  • The term "perforated portion" when used herein describes a portion where air or water is allowed to pass across the profile in question. This is to ventilate a space below the profile or to allow drainage of water away from an upper surface of the profile.
    • Specific embodiments of the invention
  • Fig. 1 illustrates an embodiment of a building construction 1 comprising a load bearing support construction 2, a plurality of underlayment profiles 3, and a covering 4 forming an external surface of the building construction 1. In the illustrated embodiment, the building construction 1 forms a roof construction, and the covering 4 comprises a plurality of tiles 4' which are configured to protect other parts of the building construction, e.g., by shedding water.
  • The plurality of underlayment profiles 3 extend in a longitudinal direction L. The support construction 2 comprises a plurality of beams 2', where the beams 2' extend in a transverse direction T. The beams 2' are offset relative to each other at a beam-distance D2 in the longitudinal direction L. The underlayment profiles 3 extend in the longitudinal direction L between two beams 2'. The two beams 2' may be two neighbouring beams, however, in the illustrated embodiment, some of the underlayment profiles 3 extend between two beams 2' where two other beams 2' are arranged between the two beams between which the underlayment profile 3 extend. In the illustrated embodiment, the transverse direction T is substantially perpendicular to the longitudinal direction L.
  • The underlayment profiles 3 each defines a plateau 5 which is fixed to the support construction 2. The underlayment profiles 3 define a barrier between an outer space O between the covering 4 and the underlayment profile 3 and an inner space I between the underlayment profile 3 and the support construction 2. The outer space O and the inner space I are illustrated in Fig. 1A being a schematical cross-section of a part of the building construction 1 of Fig. 1.
  • The underlayment profile 3 each comprises a suspension flange 6 (see also Fig. 2) which extends in the longitudinal direction L, and which connects the covering 4 and the plateau 5, whereby the underlayment profile 3 joins the load bearing support construction 2 and the covering 4.
  • The underlayment profile 3 may as an example be made of metal, such as steel or made of a plastic material, such a polyvinyl chloride (PVC). Consequently, the elongated underlayment profiles 3 can be substantially self-supporting elements. Furthermore, as the suspension flange 6 extends outwardly from the plateau 5, the covering 4 can be locked to the underlayment profile 3, whereby the underlayment profile 3 may have the function of a batten. Consequently, battens which traditionally form part of a roof construction are unnecessary.
  • In the illustrated embodiment, the building construction 1 comprises a row of underlayment profiles 3 extending in the longitudinal direction L and being fixed to the support construction 2. The underlayment profiles 3 are offset relative to each other at an underlayment-profile-distance D1 in the transverse direction T. The underlayment-profile-distance D1 is selected such that the plateau 5 of each underlayment profile overlaps the plateau(s) of adjacent underlayment profile(s), whereby the overlapping plateaus define a barrier between the outer space O and the inner space I. The size of the overlap D3 between two adjacent underlayment profiles 3 is selected based on the size of the tiles 4' along the transverse direction, whereby one row of tiles 4' corresponds to one underlayment profile 3
  • One of the plurality of underlayment profiles defines a lower bordering underlayment profile 3' which terminates the row of underlayment profiles in one direction. Another one of the plurality of underlayment profiles defines an upper bordering underlayment profile 3" which terminates the row of underlayment profiles in another direction. The remaining of the plurality of underlayment profiles define intermediate underlayment profiles 3‴ in the row of underlayment profiles. The lower bordering underlayment profile 3', the upper bordering underlayment profile 3", and the intermediate underlayment profiles 3‴ are identical, and lower bordering, upper bordering, and intermediate solely refer to the position of the underlayment profiles in the row of underlayment profiles 3.
  • Fig. 2 illustrates an embodiment of an underlayment profile 3. The underlayment profile 3 extends in the longitudinal direction L and defines a plateau 5 to be fixed to the support construction 2 (see Fig. 1). The underlayment profile 3 comprises a suspension flange 6 which extends in the longitudinal direction L for connection of the covering 4 (see Fig. 1) to the plateau 5 to have the underlayment profile 3 join the load bearing support construction 2 and the covering 4.
  • In the illustrated embodiment, the underlayment profile 3 further comprises a fixation flange 25 for fixating the underlayment profile 3 to the support construction 2. The fixation flange 25 is joined to the plateau 5 along a first edge 26 of the plateau and extends in the longitudinal direction L.
  • The fixation flange 25 defines a portion 25' with a component extending in a direction perpendicular to the longitudinal direction and transverse direction. Due to this portion, the plateau 5 can be arranged at a distance to the support construction, when fixed to the support construction, such as the beams 2'. This may allow for ventilation of the inner space I of the building construction 1 along the support construction 2 as illustrated by the arrow in Fig. 1A.
  • The suspension flange 6 is joined to the plateau 5 along a second edge 16 of the plateau. The first edge 26 and the second edge 16 are substantially parallel edges on opposite sides of the plateau5 .
  • In the illustrated embodiment, the plateau 5, the fixation flange 25, and the suspension flange 6 are made in one piece from a sheet of a plate shaped material, where both the first and second edges 26, 16 are constituted by a folded part of the plate shaped material.
  • The plateau 5 comprises a plane portion 5A defining more than 50 pct of the plateau. The non-plane part comprises a plurality of protrusions 33 acting as a water trap. The water trap 33 prevents a free flow of water between an outer surface of the plateau 5 and an inner surface of a plateau 5 of an adjacent underlayment profile 3. Without the water trap 33 there may be a risk, that water on the outer surface of a plateau may flow upwards due to wind.
  • The water trap 33 is formed by plurality of V-shaped projection which are arranged upside down. The water trap 33 comprises two rows of V-shaped projections, where the V's of one row are staggered relative to the V's of the other row.
  • A fixation rim 30 is joined to the fixation flange 25 along a fixation edge 31. The fixation rim 30 is configured to be fixed to the support construction 2 by fixation means, such as screws, nails, rivets, glue, or other similar.
  • The fixation flange 25 extends from the plateau 5 in an inward direction towards the support construction 2, whereas the suspension flange 6 extends from the plateau 5 in an outwards direction away from the support construction 2.
  • The fixation flange 25 comprises a perforated portion 13 to allow ventilation of the building construction 1, see e.g., Fig. 1A where the arrow illustrates an airflow along the beams 2' via the perforated portions of the fixation flanges 25.
  • A plurality of openings 36 are arranged along the suspension flange 6 at the second edge 16 to form a passage which forms part of a flow path across a plurality of underlayment profiles 3 to allow drainage along the plateaus 5 in the outer space O.
  • Fig. 3 illustrates an embodiment of a lower bordering support profile 7. The lower bordering support profile 7 extends in the longitudinal direction L and is configured to the located between the beams 2' and the lower bordering underlayment profile 3' (see Fig. 1).

  • The lower bordering support profile 7 comprises an upper support flange 10, a lower support flange 11, and a connecting flange 12 joining the upper and lower support flanges 10,11. Each of the upper support flange 10, the lower support flange 11, and the connecting flange 12 comprise a perforated portion 13 enabling ventilation.
  • The building construction 1 further comprises a plurality of gutter brackets 8 extending through holes 9 in the lower bordering support profile 7 (only one gutter bracket is shown in Fig. 3). The gutter bracket 8 are configured for carrying a gutter (not shown). The lower support flange 11 comprises a plurality of perforations 13 which can be transformed into holes 9 when inserting a gutter bracket 8.
  • The gutter bracket 9 extends through a hole 9 in the lower support flange 11. The gutter bracket(s) may each extend between an outer end 8A and an opposite inner end 8B, where the gutter bracket 9 can be attached to the lower bordering support profile 7 at the upper and the lower support flanges 10,11.
  • Fig. 4 illustrates an embodiment of an upper bordering termination profile 14. The upper bordering termination profile 14 is similar to the underlayment profile and defines an elongated termination plateau 15 and a suspension flange 6 joined to the termination plateau 15 along the second edge 16.
  • The elongated termination plateau 15 defines a free edge 17 opposite the second edge 15, where the free edge 17 may terminate adjacent a ridge 18 of the roof construction when arranged at the construction. As the elongated termination plateau 15 terminates in a free edge 17, it is possible to shorten the elongated termination plateau 15 to fit the size of the upper bordering termination profile 14.
  • The elongated termination plateau 15 comprises a perforated portion 13 which allows for ventilation between the inner and the outer space I, O. To minimise the risk of water ingress to the inner space I, a plurality of the holes forming the perforated portion 13 each comprises an outwardly extending collar 13' circumferentially around the holes.

In an embodiment without an upper bordering termination profile 14 (see Fig. 5), the ridge-profile 20 is to be arranged adjacent to the upper bordering underlayment profile 3", whereas the ridge-profile 20 is to be arranged adjacent to the upper bordering termination profile 14 in an embodiment comprising an upper bordering termination profile 14.
  • The ridge-profile 20 defines an elongated ridge plateau 21, a ridge flange 22 joined to the ridge plateau 21 along a ridge edge 23 extending in the longitudinal direction, and a suspension flange 6 joined to the ridge plateau 21 along the second edge 16 extending in the longitudinal direction. The ridge flange may extend upwards away from the support construction. The suspension flange 6 of the ridge-profile 20 connects the covering 4 and the plateau 21 as the suspension flange 6 of the underlayment profile 3.
