CertainTeed MemBrain: the Smart Alternative to Poly Vapour Barrier Sheeting

MemBrain moisture control reduces the risk of costly mould and mildew problems
 
Mississauga, Ontario, May 1, 2015 – CertainTeed Insulation Group Canada is proud to introduce MemBrain™, the Smart Vapour & Air Barrier Film. Moisture is an issue for every builder and the hidden risk in every home, particularly in climates with extreme seasonal fluctuations. There’s no foolproof way to keep moisture from getting into a wall but now CertainTeed has a revolutionary way to help get it out.
 
CertainTeed MemBrain looks similar to typical polyethylene sheeting, but is actually a patented polyamide-based material. What makes MemBrain unique is its ability to adapt its permeability depending on climatic conditions. 
 
Marlon Thompson, CertainTeed Marketing Product Manager, says, “While efficient insulation is essential in a home, so is the need for vapour barrier sheeting. Using MemBrain reduces risk and liability due to moisture problems. It is a high-quality, premium product but will only add about $300 to $500 to the total cost of an average 2,400-square-foot home. Using MemBrain may cost a little bit more, but it is always the smart investment.”
 
With a high resistance to water vapour in winter or low humidity, MemBrain behaves as a moisture vapour barrier like poly sheeting. When the relative humidity in the cavity increases, MemBrain’s water vapour permeability increases dramatically. This allows water vapour to escape the wall cavity easily when the humidity is high, greatly increasing the drying potential of closed building envelope systems. 
 
In addition to performing as an interior vapour barrier, MemBrain may be installed as a continuous, interior air barrier system over unfaced fibre glass or other insulation requiring a separate vapour or air barrier.
 
CertainTeed is the only manufacturer with a truly comprehensive line of insulation products and equipment, including time-tested and trusted fiberglass insulation batts and rolls, fiberglass blow-in insulation, polyurethane spray foam, innovative vapor retarder technology, and highly regarded HVAC products as well as insulation blowing and foam application equipment. 
 
All of CertainTeed’s insulation products can help building professionals qualify toward credits for both the Leadership in Energy and Environmental Design (LEED®) through the U.S. Green Building Council (USGBC) and the Green Building Standard supported by the National Association of Home Builders.
