Definitions
- the invention relates to a building covering device comprising a ribbed sheet support, a vapor barrier comprising a layer impermeable to water vapor, a thermally insulating mattress and a waterproofing membrane, mutually superimposed in this order, the waterproofing membrane covering the upper extremities of organs assembly which cross the other aforementioned constituents of the device.
- Such devices are well known and are defined for example in the French standard NF P 84-206.
- the impermeable layer of the vapor barrier is a thin sheet of aluminum, which is glued, to ensure its mechanical strength and allow its manipulation, on a glass veil with an areal mass of approximately 40 g / m 2 .
- the vapor barrier does not give the device any sound absorption property.
- the components of the device are generally assembled together by means of screws which pass through them.
- the thickness of the membrane covers the head of the screw. If a person walks in the vicinity of a screw and the porous layer of the vapor barrier crashes there, this results in a sagging of the overlying layers and the screw passes through the second layer of the waterproofing membrane, destroying the waterproofing of the roof.
- the invention relates in particular to a device of the kind defined in the introduction, and provides that the vapor barrier further comprises a layer with open porosity of a surface mass of at least 240 g / m 2 , giving the device properties of sound absorption and practically not being crushed when a person steps on it.
- vapor barrier here designates all of the layers interposed between the ribbed support and the thermal mattress insulator, which is preferably a preconstituted subset, but which can if necessary be made up of layers applied independently.
- Figures 1 and 2 show the known structure of a device of building cover.
- This device includes a support 1 made of perforated ribbed sheet steel, forming gutters 2 of trapezoidal profile, open upwards, extending parallel to each other. The edges of two neighboring gutters are connected together by a strip of material 3, the different bands 3 extending in a same plan.
- the support 1 is pierced with a multitude of holes 4 with a radius of 5 mm arranged with a mutual center distance of 12.5 mm.
- the perforation rate of the support is 22%.
- Each gutter 2 is filled with a profiled block 5 having a corresponding trapezoidal cross-section, for example formed of mineral wool and surrounded by a waterproof sheet.
- the latter may be made of high density polyethylene and used to avoid dust emission.
- Blocks 5 play the role of thermal and / or acoustic absorbent.
- the substantially continuous planar surface defined by the strips 3 and the upper face of the blocks 5 is covered a vapor barrier 6 which will be described later, on which rests a thermal insulation mattress 7 for example based mineral wool.
- Figure 1 also shows two layers 8 and 9 of a waterproofing membrane, glued to each other, as well as the flat head 10 of a screw used for the mutual assembly of components of the device.
- the lower layer 8 can be crossed by the rod of the screw, the head 10 thereof applying it to the upper face of the insulating mattress 7.
- the continuity of the membrane seal is then ensured by layer 9.
- layer 8 can cover the screw head and be glued to the mattress 7.
- the vapor barrier 6 comprises a waterproof upper layer 6a (FIG. 2) constituted by aluminum foil.
- the sheet 6a is bonded to a porous layer 6b constituted by a glass fiber veil with a surface mass of at least 240 g / m 2 .
- layer 6b can be obtained by superimposing several layers totaling a surface mass of at least 240 g / m 2 .
- Figure 3 shows the variation of the sound absorption coefficient ⁇ S , measured according to the French standard NF EN 20354, as a function of the median frequency f in hertz. The measurements were carried out on a device according to FIGS. 1 and 2, the insulating blanket being made of rock wool and having a thickness of 60 mm and a density of 160 kg / m 3 , and the waterproofing membrane being composed two layers of bitumen, each having a thickness of 3.5 mm and a surface mass of 8.8 kg / m 2 .
- Figure 4 is similar to Figure 3, and relating to a cover device in which blocks 5 have been omitted.
- the coefficient ⁇ W was also determined according to the draft international standard ISO / DIS 11654. This coefficient is equal to 0.85 with blocks 5 and 0.70 in the absence of these.
- the invention provides good characteristics sound absorption, especially when blocks 5 are present, but also when they are omitted.
