Vapor Barrier Dorken Delta Fol PVE It is a vapor barrier screen with reinforcing mesh. Particularly heat stable with great tear resistance.
GENERAL
- It is made of four layers of material. Highly tear-resistant armor, non-woven with special coating.
- Waterproof, UV stabilized and bitumen free.
- It is heat stable and can be laid easily, without any problems even when temperatures are high.
- It is particularly robust thanks to the optimised protection of the coating. The high abrasion resistance and excellent anti-slip properties make it easy to install.
- Weatherproof.
- With a weight of 165 g/m2 and the practical roll width of 1.50 m, it guarantees high installation performance at low costs.
- The thin thickness of the material allows for the most complicated and difficult to access areas of the roof to be created without great difficulty.
APPLICATIONS
As a waterproof vapor barrier screen in thermal insulation protection systems for pitched roofs. Placed under the thermal insulation, it allows for the regulation of the flow of water vapor, preventing the formation of interstitial condensation and ensuring airtightness by sealing the overlaps with suitable adhesive strips or DELTA ® glues.
