Definitions

the invention relates to a plastic roof membrane in sheet form for pitched roofs and the like, the roof consisting of beams and rafters, arranged between the rafters thermal insulation material, the rafters and the thermal insulation material by a vapor barrier on the roof inside and the rafters through the roof membrane on the outside of the roof are covered, on which a counter battens is arranged to form a ventilation space and a roof battens, which serves as a support for the roof covering.
a relatively thick fleece layer must be used for the production, since this must have a high degree of inherent stability for the subsequent coating process.
the coating by means of a paste is also of considerable thickness, which leads to a high use of materials.
the production is relatively time-consuming and therefore expensive.
the invention has for its object to provide a sarking membrane of the type mentioned, which on the one hand is so open to diffusion that it can be installed directly on the thermal insulation, regardless of whether the vapor barrier is built properly or at all, on the other hand, it is also able to avoid the negative effects of condensing water vapor in the event of shock loads, and which has a high level of strength with a significantly lower use of material and enables economical, large-scale production.
the underlay is formed from polyether block amides of the hydrophilic type, the underlay being designed as a moisture store.
Suitable polyether block amides are commercially available under the name "PEBAX” (registered trademark of ATO CHIMIE).
the chemical structure of these products is formed by a linear, regular chain of rigid polyamide and flexible polyether segments.
a particularly suitable material is commercially available under the designation 4011 RN 00.
the teaching according to the invention of forming a sheet-like underlayment from this material results in the result that on the one hand the underlayer can be laid directly on the thermal insulation, since excellent vapor permeability can be achieved, but on the other hand the underlayer itself can also be used as a moisture accumulator in the event of shock loads, such as when expelling the new building moisture, to temporarily store it from condensing water vapor.
the stored liquid is then gradually released, depending on the diffusibility of the underlayment until the vapor pressure is equalized. In this way it is avoided that dripping water forms and this dripping water gets into the thermal insulation or to the underlying materials.
the adaptation of the storage capacity to the moisture that may occur can be achieved by an appropriate thickness dimensioning or an appropriate one Material selection made.
the sarking membrane made of the material designated as preferred above can hold up to 120% of its own weight in water as storage.
the underlay 1 consists of polyether block amides (PEBA) of the hydrophilic type.
PEBA polyether block amides
the material which is available in granular form, is processed into a film which can be adjusted according to its storage capacity with regard to the material and / or with regard to its thickness.
the film according to the invention is on the one hand permeable to water vapor and on the other hand suitable for storing liquid, the material being able to store up to about 120% of its own weight in water.
