Serial No. 527,992

1 Claim.

It is found that brick and concrete walls are more or less pervious to both air and moisture, since wind and moisture will penetrate rapidly through a relatively thin, poorly constructed wall of brick or concrete; and even when a wall is a foot or more thick and is carefully constructed of good grade bricks and mortar, considerable air will filter through the wall under the action of a strong wind and when a substantial difference in air pressure exists at the opposite faces of the wall.

It is commonpractice in constructing brick or concrete houses and other buildings having a finished interior, to space the plaster supporting structure, or the like, a short distance from the inner face of the brick or concrete wall to provide a dead air space therebetween which will increase the insulating properties of the entire wall and decrease the likelihood of the moisture that penetrates through the brick or concrete wall injuring or discoloring the inner finished wall structure.

While the air space just mentioned helps to keep the inner finished wall dry and to improve the insulating properties of the composite wall structure, a considerable infiltration of air from the exterior to the interior of the building through the walls will take place particularly when there is a strong wind, or a pronounced difference in temperature between the interior and exterior of the building.

The present invention therefore contemplates an air tight and moisture impervious lining for the inner face of a brick or concrete wall which may be readily secured to the inner face of the wall to protect the inner finished wall structure of the building from moisture and from infiltration of air through the brick or concrete wall.

More specifically the present invention relates to a building construction consisting of a brick or concrete wall having a covering of reenforced, moisture-proof paper secured between the inner face of said wall and the inner finished wall structure of the building to form an air and moisture tight lining therebetween.

The novel features of the present invention will be further understood from the following description when read in connection with the accompanying drawing showing good practical forms of the invention.

In the drawing:

Fig. 1 is aperspective view of a brick wall having the lining of the present invention provided between the inner face of the wall and the supporting structure for the inner finished wall.

Fig. 2 is a similar view of a slightly different construction.

Fig. 3 is a perspective view of a sheet of reenforced moisture-proof paper which is well adapted for use in lining a wall in accordance with the present invention; and

Fig. 4 is a horizontal sectional View of a modification of Fig. 1.

While the features of the present invention are well adapted for use in connection with walls formed of brick, tile, concrete or other fire-proof materials, they are illustrated in the drawing in connection with the brick wall 10 which may be of the usual or any preferred construction.

As above pointed out, brick and concrete walls even when carefully constructed of high grade material are more or lesspervious to air and moisture. The present invention therefore contemplates a lining for the inner face of the wall 10 which is impervious to air and moisture and which is strong, durable and relatively inexpensive. The lining of the present invention is formed of moisture-proof paper and preferably of a multiply, reenforced, water-proof paper 11 which may be given any width convenient for handling. These strips are secured to the inner face of the wall 10 in either a vertical or horizontal position, the latter arrangement being shown, and the adjacent edges of the strips of paper preferably overlapping as at 12. The overlapping edges of the sheets 11 are, preferably secured together to form an air tight or substantially air tight joint between them, and in the construction shown in Fig. 1 the overlapping edges of the sheets 11 are secured together by the row of tacks or nails 13 driven into the wall 10, while in the construction of Fig. 2 the overlapping edges are shown as secured together by the adhesive 14.

In constructing houses and other buildings having a finished interior it is customary to support the inner wall forming structure in spaced relation to the. inner face of the wall 10 to provide an air space therebetween and in Fig. 1 such inner wall structure is shown as formed in a well known manner by providing the furring strips 15 which are nailed or otherwise secured to the wall 10, and tothese strips 15 are secured the laths 16, adapted to support the usual layer of plaster 1'7.

In the construction shown in Fig. 2 insulating or plaster boards 18 are shown as secured to the furring strips 15 in place of the laths 16, and the outer face of the boards 18 is covered with plaster as at 19.

The lining of moisture-proof paper 11 may be secured directly against the wall 10 as shown in Figs. 1 and 2, or it may be supported in spaced relation to this wall as shown in Fig. 4, and the paper is conveniently held in place by securing the furring strips 15 to the wall over the paper as shown.

While various forms of moisture-proof paper may be employed in accordance with the present invention to provide a wind and moisture-proof covering between the inner face of the wall 10 and the finished inner wall of the building, excellent results are secured through the employment of a two-ply, reenforced, moisture-proof paper comprising the two sheets of paper 20 and 21 secured together by a water-proof adhesive.

such as black asphaltum, and the paper is preferably reenforced both longitudinally and transversely with straightenedunspun fibres 22 and 23.

In some cases it may be desirable to support the paper 11 out of contact with the wall 10. This is readily accomplished as shown in Fig. 4 by providing the furring strips 15 at both sides of the paper 11.

It will be seen from the foregoing that when the inner face of a brick or concrete wall is lined with strong durable sheets of reenforced moistureproof paper in accordance with the present invention, the passage of air and moisture through the outer wall 10 to the inner finished wall structure is prevented, and as a result the interior of the building will be considerably easier to maintain at the desired temperature than heretofore.

What is claimed is:-

In a building structure, the combination of a brick or concrete wall which is more or less pervious to air and moisture, an inner wall structure secured to the brick or concrete wall in spaced relation thereto to provide an air space between said walls, and a wind and moisture excluding lining comprising. multiply sheet material, one at least of the sheetsbeing formed of paper reenforced and strengthened by unspun fibres held between the sheets by a waterproof adhesive, said multiply material being secured between the brick or concrete wall and inner wall structure and sup ported inspaced relation to both walls so as to provideiran air space at both sides of the paper and prevent the moisture and wind which penetrates through the outer wall from reaching the inner wall.
