Introducing the Vapour Barrier Black 125Mu - a high-quality and BBA approved solution that meets NHBC requirements for effective moisture prevention. Designed to protect concrete and timber frame structures, this vapour barrier provides a reliable and durable barrier against unwanted moisture infiltration. With its waterproof properties and robust construction, it offers peace of mind and long-lasting protection.

This vapour barrier is engineered to prevent moisture seeping into concrete and timber frames, safeguarding the integrity and longevity of the construction. It acts as a dependable shield, keeping unwanted moisture at bay and reducing the risk of damage caused by dampness. By creating a barrier between the building materials and external elements, it helps maintain a dry and healthy environment.

The Vapour Barrier Black 125Mu is not only waterproof but also rot-proof, ensuring its durability even in challenging conditions. Its 500 gauge thickness adds an extra layer of strength and protection, making it resistant to tears and punctures. This robustness guarantees its effectiveness in withstanding the rigors of construction and providing long-term moisture control.

Installing this vapour barrier is hassle-free and straightforward. With its user-friendly design, it can be easily laid out and cut to fit the required dimensions. The roll size of 4mx25m offers ample coverage, making it suitable for various applications.
