Air Tightness & Vapor Control

Vapor Barriers for Safe and Airtight Constructions

Vapor barriers regulate moisture transfer within the building structure and permanently protect insulation and construction components against moisture damage and mold growth.

Especially in energy-efficient buildings, renovations and modern timber constructions, high-quality vapor barriers ensure a safe and durable building envelope.

Variable Vapor Control Membranes

Variable vapor control membranes adapt their diffusion resistance depending on humidity conditions. This allows moisture within the structure to dry out in a controlled way and provides additional safety for renovations and modern timber constructions.

Matching Airtightness Systems

Professional sealing of all joints and transitions is essential for a durable airtight layer. In our online shop you will find suitable products for airtight connections and energy-efficient construction systems.

Frequently Asked Questions

What is the difference between a vapor barrier and a vapor retarder?

Vapor retarders allow controlled moisture transfer within the construction, while vapor barriers have a significantly higher diffusion resistance.

When are variable vapor control membranes used?

Variable vapor control systems are especially suitable for renovations, timber constructions and diffusion-open building assemblies.

Why is airtight installation important?

Leaky joints can lead to moisture damage, mold growth and unnecessary heat loss.
