Definitions
- the present invention relates to a roofing material made of elements which overlap one another, which is waterproof against water, snow or ice and permeable to air or vapor.
- These discrete elements can be tiles, slates, or any other system making it possible to obtain a seal by imbrically or by covering like fish scales.
- This roofing material is generally placed between the support of the tiles and the frame.
- Existing materials have so far been completely waterproof materials, such as plastic films or bituminous felts.
- Plastic materials materials such as impregnated cellulosic felts, have neither the porosity sufficient to allow the roof to breathe while keeping a good seal, nor the resistance necessary to allow safe use in roofing.
- French patent n ° 2,098,475 describes a roof insulation strip formed by filaments or thermoplastic fibers heated to seal against liquids while allowing air to pass through.
- US Patent No. 3,756,895 also relates to a roof covering composed of several layers of glass fibers with a microporous surface membrane made of polyester and polyurethane fibers.
- the invention presents a roofing material which is at the same time waterproof to liquid or solidified water, allows air and water vapor to pass, and resists falling objects or people during its use.
- This material consists of a sheet of fibers agglomerated by conventional means, for example non-woven polyester, non-woven polypropylene, non-woven polyethylene (non-limiting choice), this sheet is coated on one side using conventional means of a very thin microporous layer of bitumen, the characteristics of which are completely different from the thermoplastic fibers of the prior art.
- the coating is regulated, as well as the quality of the bitumen, to have a quantity just sufficient to blacken the nonwoven but which allows by removal of the bitumen during its cooling, to obtain a micro-cracked and micro-perforated surface thus giving to the material, on the one hand, the permeability to air and to the desired water vapor, and, on the other hand, the seal, desired héity.
- the holes thus formed in the material are too small for water, because of its surface tension, to pass, and on the other hand are large and numerous enough for air and water vapor to circulate on both sides across the sheet.
- the surprising aspect of the invention lies in this association of a nonwoven with a bitumen in sufficient health to obtain a continuous surface but pierced with holes, which is the opposite of the effect sought by the usual users of these materials which produce perfectly waterproof materials.

Abstract
Description
- La présente invention concerne un matériau de sous-toiture en éléments se recouvrant les uns les autres, qui soit étanche à l'eau, la neige ou la glace et perméable à l'air ou la vapeur.
- Il est connu des hommes de l'art qu'il est nécessaire d'isoler contre les pénétrations d'eau, de neige, les toitures re- couvertes de matériaux de couverture faits d'éléments discrets.
- Ces éléments discrets peuvent être des tuiles, des ardoises, ou tout autre système permettant d'obtenir une étanchéité par imbriquement ou par recouvrement comme des écailles de poisson.
- Ce matériau de sous-toiture est placé en général entre le support des tuiles et la charpente. Les matériaux existants sont jusqu'à présent des matériaux parfaitement étanches, comme par exemple les films de matière plastique ou les feutres bitumés.
- Les matériaux en matières plastiques, les matériaux comme les feutres cellulosiques imprégnés, n'ont ni la porosité suffisante pour permettre à la toiture de respirer tout en gardant une bonne étanchéité, ni la résistance nécessaire pour permettre un emploi en toiture sans danger.
- D'autre part pour des raisons économiques et pratiques de légèreté, ces matériaux ont des caractéristiques mécaniques faibles et qui entraînent pour le poseur de tuiles un certain danger de manipulation.
- Pour mieux expliquer ce double problème, on peut prendre deux exemples précis
- 1. un des matériaux employé est le film de polyéthylène. Le film de polyéthylène parfaitement étanche, s'il empêche bien l'eau de rentrer dans un bâtiment, retient cette eau entre la charpente et le support des tuiles, Il s'ensuit que le toit ne pouvant pas "respirer", le support de tuiles risque de pourrir dans un délai très restreint à moins que l'utilisateur ne vienne percer en de nombreux endroits le film de polyéthylène pour rétablir la circulation d'air dans la toiture, mais il perd à ce moment là la protection contre les infiltrations d'eau.
- 2. Ce matériau, lorsqu'il est utilisé par le couvreur présente un certain danger de manipulation.En effet, lors de la pose des liteaux, il ne voit plus la charpente. Il s'ensuit donc pour lui un défaut de précision dans la localisation des points d'appui sur lesquels il va marcher et le cas échéant, il risquera de passer à travers le toit.
- Le brevet français n° 2 098 475 décrit une bande d'isolement de toiture constituée par des filaments ou fibres thermoplastiques chauffées pour assurer l'étanchéité aux liquides tout en laissant passer l'air.
- Le brevet américain n° 3 756 895 concerne également un revêtement de toit composé de plusieurs couches de fibres de verre avec une membrane superficielle microporeuse constituée de fibres de polyester et de polyuréthane.
- L'invention présente un matériau de sous-toiture qui est en même temps étanche à l'eau liquide ou solidifiée, laisse passer l'air et la vapeur d'eau, et résiste à la chute d'objets ou de personnes lors de son utilisation.
- Ce matériau se compose d'une nappe de fibres agglomérées par un moyen conventionnel, par exemple non tissé de polyester, non tissé de polypropylène, non tissé de polyéthylène (choix non limitatif), cette nappe est enduite sur une seule face à l'aide d'un moyen conventionnel d'une très fine couche microporeuse de bitume, dont les caractéristiques sont totalement différentes des fibres thermoplastiques de la technique antérieure.
- L'enduction est réglée, ainsi que la qualité du bitume, pour avoir une quantité juste suffisante pour noircir le non tissé mais qui permette par retrait du bitume lors de son refroidissement, d'obtenir une surface micro-craquelée et micro-trouée donnant ainsi au matériau, d'une part la perméabilité à l'air et à la vapeur d'eau souhaitée, et d'autre part l'étan- c,héité désirée.
- En effet, les trous ainsi formés dans le matériau sont trop petits pour que l'eau,à cause de sa tension superficielle, puisse passer, et par contre sont suffisamment importants et nombreux pour que l'air et la vapeur d'eau puissent circuler de part et d'autre à travers la feuille.
- Le côté surprenant de l'invention réside dans cette association d'un non tissé avec un bitume en quantité suffis santé pour obtenir une surface continue mais percée de trous, ce qui est l'inverse de l'effet recherché par les utilisateurs habituels de ces matières qui fabriquent des matériaux parfaitement étanches.
-
- 1. matériau constitué d'une nappe de non tissé de polypropylène d'un poids au m2 de 135 g, enduite sur une face de 300 g de bitume 90/30, la face bitumineuse étant protégée par un anti-adhérent grès, talc, sable, etc... à l'exclusion des films plastiques ;
- 2. matériau constitué d'une nappe de non tissé polyester d'un poids de 85 g/m2 enduite sur une face de 250 g de bitume fillerisé 90/30 protégée par un grésage ;
- 3. matériau constitué d'une nappe de non tissé polyéthylène d'un poids de 150 g/m2 enduite sur une face de 250 g de bitume fillerisé 90/30 protégée par un grésage,
- 4. matériau constitué d'une nappe de non tissé de fibres polyvinyliques de 200 g/m2, enduite sur une face de 250 g de bitume fillerisé 90/30 protégée par un grésage.
