Avoid mold and air leaks now – to avoid headaches later

When you’re starting a home renovation project, you need to think about more than what your walls will look like when you’re done. You need to think about what’s going inside them, because along with holding up the house, their job is to keep out air and moisture.

The walls can’t do it on their own, and it takes more than drywall and insulation. If you don’t address the issue now, before your walls are closed up, you could be in for costly repairs later.

It just makes sense. The answer is MemBrain, CertainTeed’s revolutionary, patented solution that combines continuous air barrier protection and advanced moisture management into a single product. It’s intelligent, one-step protection from air leaks and moisture.

Stop air leaks
Air will find its way through every gap in your home, no matter how miniscule. With it come not only unpleasant drafts, but also moisture, pollutants, allergens and noise. Conventional air sealing measures may help, but they also create another challenge: trapped moisture.
MemBrain is smarter than that.

Help prevent mold
Moisture is unavoidable. It enters wall cavities from the outside in summer and from the inside in winter. There it creates a breeding ground for mold, mildew and wood rot. A vapor barrier – typically an impermeable poly film – can actually make this problem worse by trapping moisture inside the walls.
MemBrain is smarter than that. When the humidity outside is low, MemBrain remains moisture-tight to prevent the moisture generated by normal indoor activities, such as cooking, bathing and laundry, from seeping into the walls. When the humidity is high, it opens up to allow moisture buildup to escape into the conditioned environment of your home, keeping your walls dry year-round.

Air leaks and moisture: Why they matter
What happens if you don’t pay attention to air tightness and moisture management? Your indoor air quality can be seriously compromised. Asthma and allergy triggers can sneak in from outside, and if mold gets a foothold, its spores will find their way in to make things even worse. When moisture condenses on the insulation, its performance – and your home’s energy efficiency – take a nosedive. When it condenses on wood framing, rot can get started and lead to serious structural damage.
MemBrain is smarter than that. Serving double-duty as an air barrier and smart vapor retarder, MemBrain helps protect your family and your home. It’s an important part of creating a home of Complete Comfort. And after all, if it’s not complete, it’s not comfort.

Don’t seal your home, don’t manage moisture – and there will be consequences. Why risk them?
TRUTH: Air you pay to heat and cool leaks out
TRUTH: Outdoor pollutants leak in
TRUTH: Moisture gets into your walls
TRUTH: Moisture stays trapped in your walls
TRUTH: Moisture condenses on wood framing
TRUTH: Do nothing now
