It is an SD 20 (Diffusion‐equivalent air‐layer thickness equivalent to 20M) airtight,
highly diffusive and very sturdy vapour barrier for roof extensions in accordance with the latest EnEV
guidelines. It is used in constructions where a permeable vapour barrier is required and
can be utilised in new build and renovated roofs
APPLICATIONS
3 months resistance to UV and exposure to bad weather for easy insulation from the exterior.
Interior Usage
Supports energy efficiency and prevents uncontrolled heat loss
Its moisture‐regulating properties promote the drying‐out of a thermally‐insulated roof space in
summer as well as protecting from condensation in winter
Permits the creation of an airtight building envelope and as a result, prevents draughts occurring in a
house.
It is used in constructions where a vapour barrier allowing diffusion is required
and is used in new constructions as well as renovations.
