Vapor permeable foil Fol-N 125g/m2 /75m2 TONDACH

The TONDACH FOL-N 125 g/m² vapor-permeable foil is designed as a high-quality preliminary layer for roofs, which provides effective diffusion removal of water vapor and protection against water penetration. The product is suitable for all ventilated and non-ventilated roofs and can be used under various roofing materials such as ceramic and concrete tiles, sheet metal, etc. With a weight of 125 g/m² and optimal strength, the membrane guarantees reliable performance and durability of the roof structure.

Designed with attention to detail, TONDACH FOL-N offers excellent resistance to external conditions while allowing the free passage of vapor, preventing condensation under the roof. Temperature resistance from -30°C to +80°C and high water resistance (class W1) provide reliable protection in various climatic conditions, maintaining an optimal energy and humidity balance in the roofing system.
