Vapor barrier membranes
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.
Applications
- Pitched roofs and roof renovations
- Between-rafter insulation
- Timber frame construction
- Interior insulation systems
- Ceiling constructions
- Airtight wall assemblies
Important Factors
- Correct sd-value selection
- Professional sealing of all joints
- Coordinated wall and roof assemblies
- Protection against moisture and heat loss
- Durable airtight construction
- Reliable drying capability
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.
