Airtightness membrane

Airtightness membrane

Pro Clima vapor control layers and airtight membranes

Pro Clima vapor control layers and airtight membranes form the foundation for a permanently airtight and secure building envelope. They prevent uncontrolled air movement and reliably protect structures from moisture damage.

Humidity-variable vapor control layers, in particular, offer a high level of safety by adapting their diffusion resistance to environmental conditions. This regulates moisture while allowing building components to dry out.

The systems are suitable for use in roofs, walls, and in combination with blown-in insulation. As a specialist supplier, we offer coordinated products and support you in selecting the right solutions for your construction project.

Vapor control layers and airtight membranes for maximum structural safety

Pro Clima vapor control layers and airtight membranes ensure a permanently airtight building envelope and reliably protect structures from moisture damage. They prevent uncontrolled air movement and reduce heat loss, significantly improving the building’s energy efficiency.

Modern systems, especially humidity-variable vapor control layers, adapt their diffusion resistance to environmental conditions. This reduces moisture ingress in winter while enabling drying in summer, increasing the safety of the structure and ensuring long-term dry building components.

The membranes are suitable for use in roofs, walls, and ceiling constructions and can be combined with various insulation materials. In combination with coordinated adhesive systems, they create a reliable airtight solution for new construction and renovation.
