Gerband SD Control Airtight Membrane is a double-layered vapour barrier designed for superior airtightness and vapor control in internal roof and wall constructions. This high-performance membrane reliably prevents the diffusion of interior humidity into the roof and wall, ensuring optimal protection for your building. This airtight membrane meets all valid requirements of the EnEV and construction standards, offering excellent ageing resistance and durability.
Key Features:
- Airtightness & Vapor Control: Enables airtightness and vapor control, crucial for roof and wall constructionwith its variable Sd feature. This unique feature enables the membrane to reliably prevent diffusion of interior humidity into the roof and wall construction in winter whereas during summer it allows for back fusion from the insulation as well as the wall and roof construction. The ress prevents condensation that facilitates mildew growth and constructional damages.
- Reliable Protection: Acts as a reliable vapour control layer, preventing condensation that can facilitate mildew growth and constructional damage.
- Durability: Excellent ageing resistance according to DIN EN 13984, providing necessary security for long-term application.
- Installation: Should be applied perpendicular to the direction of the application surface, such as rafters and joists, ensuring an airtight seal.
- Standards Compliance: CE sign according to DIN EN 13984, guarantees compliance with international standards.
Benefits:
- Prevents Humidity: Reliably prevents the diffusion of interior humidity into the roof and wall, protecting against condensation and mildew growth.
- Energy Efficiency: Contributes to the overall energy efficiency of passive house systems, ensuring optimal insulation performance in both summer and winter.
- Versatile Use: Suitable for indoor use as a vapour barrier, protecting the construction according to DIN 4108 standards.
- Easy Application: Designed for straightforward installation on construction sites, ensuring an airtight layer for the protection of your building.
Applications:
- Roof and wall construction
- Passive house systems
- Insulation layers
- Construction sites in various climates, including winter and summer conditions
