Definitions
- the invention relates to a roof ventilation with a roofing membrane that is used on a thermal insulation Insulation layer lying between this and an outer one Roof skin, such as a roof covering, under training one between the roof membrane and the roofing membrane extending outer roof channel is arranged.
- roof structures with ventilation ducts represents a common measure today to avoid Damage otherwise caused by not drying out penetrating moisture or condensation can.
- a second extends parallel to it inner channel between the roofing membrane and the Thermal insulation. Keeping the insulation material dry done by convection, i.e. in that the named air flows through the inner roof channel and possibly existing moisture is carried along.
- From DE-A-33 18 380 and CH-A-645 693 are also already Previously known roof vents, in which between a sarking membrane and a thermal insulation layer from the Eaves edge of a roof extending to its ridge Channels are provided.
- the invention is intended to be a simplified one Roof ventilation is created, which is the convective ventilation principle operated and with direct Laying the sarking membrane on the thermal insulation in the Construction is easier than the previously known roof ventilation.
- This task of the invention is solved in that at a Roof ventilation according to the preamble of the claim 1 the sarking membrane on its thermal insulation facing side with recess from the whole underlay continuous channels extending between the eaves and the ridge with spacers is equipped, which is in one piece with the sarking membrane are trained.
- the sarking membrane itself is by means equipped when placed on a thermal insulation layer Form ventilation ducts that wick away moisture enable from the thermal insulation layer.
- the distance means can have a surface structure according to the Have kind of a corrugated sheet, the elevations and Wells between the eaves and the ridge form running channels.
- the distance means can also be made from each other spaced ribs exist, each at the same height protrude from the underlay and underneath Formation of channels between the eaves edge and the Extend ridge.
- the distance means expediently run formed channels perpendicular to the ridge line. You can but also at an angle different from 90 ° Ridge line run.
- the distance means can also be made from each other spaced pimple-like elevations that exist spaced apart from each other at the same height on the underside protrude from the roofing membrane, whereby in the laid State the gaps between each other spaced knobs regardless of the direction of installation Form the underlayment flow channels.
- the distance means are in one piece with the sarking membrane trained and can be molded directly from this be, for example in the form of expressions, or by the
- the roofing membrane is designed as a corrugated sheet overall.
- the underlay can be loosely overlying the thermal insulation layer or with it be connected connected.
- Another solution to the object of the invention provides that at the roof ventilation according to the preamble of the claim 9 the sarking membrane on its thermal insulation facing side with a pore-open structure Foam, wire or plastic mesh is provided.
- a structure provides suitable ventilation channels willing to stand between the thermal insulation and a the upper end of the underlayer film extend.
- the pore-open structure made of wire or plastic mesh exists, has also proven to be advantageous Structure on its side facing the thermal insulation with a lamination of a perforated film or an air-permeable fleece.
- Such Laminating prevents that when laying the sarking membrane directly on the thermal insulation or plastic mesh with mineral or synthetic The fibers of the insulation materials are caught. Nevertheless, can Water vapor can pass through the lamination and convective in the adjoining channel be dissipated.
- Thermal insulation layer 10 made of mineral or synthetic Fibers, but also made of foam, styrofoam or similar suitable insulation materials can exist.
- Thermal insulation layer 10 made of mineral or synthetic Fibers, but also made of foam, styrofoam or similar suitable insulation materials can exist.
- Underlay 12 which on the to the thermal insulation layer indicating a corrugated sheet-like profile spaced and parallel ribs 13 and each extending between the ribs 14 owns.
- the underlay 12 lies with the above Ribs 13 on the top of the thermal insulation layer 10 and is laid so that the ribs 13 and channels 14 in extend the fall line of the roof, so perpendicular to Ridge line run.
- the sarking membrane 12 is in its own right in FIG. 3 illustrated. It can be seen that on the Thermal insulation layer 10 installed underlay 12 extending between adjacent undulating elevations Form depressions flow channels 14 which at a Roof throughout from its eaves to the ridge pass. These channels 14 form, without prejudice to lying on the ribs 13 of the underlay 12 on the thermal insulation layer, inner roof channels through which air flows and thus a permanent keeping of the thermal insulation layer 10 ensure.
- the underlay 16 shown in Fig. 4 differs of the sarking membrane 12 according to FIG. 3 in that instead of a wavy structure on the underside of the Ribs 17 of rectangular shape protrude that are spaced and parallel to each other below Formation of flow channels 18 between each adjacent ribs 17 run.
- the roofing membrane 16 is in the same way as the lower part 12 according to FIG. 4 to lay a thermal insulation layer 10 of a roof, wherein the ribs 17 on the upper side on the thermal insulation layer 10 rest and the ones formed between the ribs Channels 18 from the eaves of a roof to its ridge extend and in turn effective ventilation and thus ensure dehumidification of the thermal insulation layer 10.
- knob-like elevations 21 In contrast to the underlays according to FIGS. 3 and 4 are in the underlay shown in Fig. 6 20 spaced apart from each other on the underside arranged knob-like elevations 21 in front.
- these knob-like elevations 21 on the top of the Insulation layer 10 on and between the latter and the Underlay membrane 20 forms a multiplicity of flow paths 22, which is also effective ventilation and thus ensure dehumidification of the thermal insulation layer 10.
- Underlay membrane 30 consists of a film sheet 31 and a on the side facing the thermal insulation layer 33 Film web 31 applied structure 32 from a Wire mesh.
- This wire mesh structure 32 is open pores, firmly connected to the film web 31 and on the side facing the thermal insulation layer 33 with a Lamination 34 made of a perforated plastic film or a very breathable fleece.
- a such lamination prevents when laying the Underlay directly on the thermal insulation layer 30 Interlocking of the rotating mesh structure 32 with mineral or synthetic fibers of the insulation materials. Through the Lamination 34 can allow water vapor to pass through and transported away convectively in the adjoining channel become.
- the pore-open wire mesh structure provides air through-flow ventilation channels ready and forms the Channel, through which water vapor is convective is dissipatable.
- the rigidity of the wire mesh structure 32 is chosen so that it is the pressure of the insulation material can withstand that between the insulating material 33 and the film web 31 the underlayment 30 air channels remain permanently.
