INSTALLATION

For most areas, vapor retarders should be installed on the warm-in-winter side

of the insulation (toward the interior). For some warm and humid areas, the

vapor retarder should be installed towards the exterior of the building envelope.

MemBrain is not intended to be used as an exterior vapor retarder. Check local

practice and/or building codes.

Installation in wood framing: Same as polyethylene sheeting.

Please see MemBrain Installation Instructions For Wood Framing and Steel

Framing (30-28-142).

Installation as an Air Barrier System: MemBrain may be installed as
