Introduction
VAEPLAN® is a multifunctional synthetic membrane known for its reliability and high durability, developed by DERBIGUM France. With over 40 years of experience, VAEPLAN membranes are recognized for their quality and longevity.

Material Characteristics
The membranes are made using VAESTOMERE technology, which combines vinyl and acrylic polymers to create a flexible and stable copolymer. This technology ensures the membranes maintain their technical properties for over 40 years.

Application and Installation
VAEPLAN membranes can be applied quickly due to their simple system and dual welding techniques (hot air and cold welding). They are suitable for various applications, including inaccessible, accessible, vegetated, or garden roofs. The membranes can be mechanically fixed, laid freely, or adhered with cold glue.

Durability and Repair
The membranes offer reliable welds that are as strong as the material itself, ensuring long-lasting durability. Repairs and modifications are easy, even after 30 years, as proven by studies conducted by MPA Braunschweig in 2009.

Compatibility and Environmental Impact
VAEPLAN membranes are compatible with bitumen, all types of insulation, and old waterproofing systems, eliminating the need for a separation layer. They are fully recyclable, and production waste is directly recycled. The membranes are also suitable for rainwater recovery and reuse.

Performance Features
VAEPLAN membranes have a high vapor diffusion capacity, reducing condensation risk significantly. They are fire-resistant, with a Broof(t3) classification and self-extinguishing properties. Additionally, they are root-resistant, making them ideal for green roofs.

Chemical and Damage Resistance
The membranes are resistant to oils, greases, and a wide range of chemicals. Their homogeneous composition and polyester reinforcement provide high impact resistance and durability.

Conclusion
VAEPLAN membranes offer a proven durability of 30 to 40 years, with exceptional welding quality and flexibility. They are suitable for all types of roofs and applications, providing a reliable and sustainable waterproofing solution.
