This Variable Surface Diffusion Membrane can be used as an air tight barrier and vapour control layer for internal walls and roof linings. Offering effective moisture control during varying conditions.
Should only be used on the warm side of the insulation. Perfect for using in Campervan conversions.
The membrane is reinforced for increased tear resistance and is suitable for installation alongside many insulation systems.
The water vapour transmission (s.d.) value varies from 0.4-100.
