Airtightness: Opt'Air foaming membrane

This new airtight membrane is to be placed directly on the inside of the masonry, whatever the nature of the material.
Airtight, it is nevertheless permeable to water vapor.
Its direct laying on the internal face of masonry by marouflage, allows a simple and fast implementation. It avoids any holes or cuts when laying the insulation on the surface it covers.

This membrane adheres to most materials. For the rest, its installation must comply with the laying rules identical to those recommended for the membranes covering the insulation, both at the outer edges (gluing) and overlays (adhesive).
Its transparency facilitates the implementation of the Optima insulation system since this dry solution is compatible with Isover airtight accessories.
