## Long description

The Building Waterproofing Foil 5x20m is a professional-grade solution designed to provide a reliable moisture barrier for a wide range of construction and renovation tasks.

Its robust construction ensures durability during installation and throughout its service life, making it an essential component for maintaining the structural integrity of various building elements.
Advantages
This waterproofing foil is engineered for high performance in demanding construction environments. Its primary advantage lies in its ability to create a seamless protective layer that prevents moisture from penetrating into insulation materials or structural components. The material is lightweight yet tear-resistant, which simplifies the handling and installation process on site. By effectively managing moisture levels, it helps to prevent the development of mold and rot, thereby extending the lifespan of the building materials it protects. Its versatility allows it to be used across different stages of construction, from initial roofing to final flooring preparations.
Suitable for
Roofing underlayment systems
Moisture protection for concrete flooring
Wall insulation barrier applications
Temporary protection of building materials during construction
Renovation projects requiring damp-proofing
When it may not be suitable
This foil is not intended for use as a primary roofing membrane exposed directly to UV radiation or extreme weather conditions without proper covering. It should not be used in applications requiring high-temperature resistance or as a structural load-bearing component.
Key specifications
Dimensions: 5 meters by 20 meters
Material: Durable moisture-resistant polymer
Function: Waterproofing and vapor barrier
Application: Roofing, flooring, and wall insulation
How to use
To install the waterproofing foil, ensure the surface is clean, dry, and free of sharp objects that could puncture the material. Unroll the foil across the intended area, ensuring sufficient overlap between adjacent sheets to maintain a continuous barrier. Secure the foil using appropriate fasteners or specialized adhesive tapes designed for vapor barriers to seal the joints. Ensure the material is laid flat and taut to prevent water pooling or air pockets. When used in roofing or wall applications, always follow the specific layering sequence recommended for your insulation system to ensure optimal performance.
What to consider before purchase
Measure the total surface area to ensure the 100 square meter coverage is sufficient for your project.
Verify compatibility with your specific insulation materials and building structure.
Ensure you have the necessary sealing tapes or fasteners for a complete installation.
Usage recommendations
For best results, always overlap the edges of the foil by at least 10-15 centimeters and seal all seams with high-quality construction tape to ensure a completely airtight and watertight barrier.
