DB+
Reinforced Vapour Control Layer and Airtightness Membrane
Advantages
- High protection against structural damage and mould, even in the event of unexpected moisture ingress
- Protection in winter climate with MVTR-value of 20 MNs/g
- Back diffusion in summer with MVTR value of 2 MNs/g
- High tear-resistance
- Suitable for all fibrous thermal insulation (also blown-in insulation)
- Ecological solution for sealing the building envelope
- Lowest VOC rating in hazardous substance test
Areas of application
DB+ is the original humidity-variable vapour control layer. It is a reinforced, cellulose-based vapour control layer and airtightness membran for protecting insulation in timber frame construction.
