Moisture Management

Moisture vapor can enter the home through external air leakage and everyday indoor activities. An average family of four can generate 2-3 gal of water vapor/day from cooking, bathing, washing dishes and laundry. When moisture vapor penetrates the wall cavity, it can condense on cold surfaces and accumulate in the building envelope.

When you manage moisture, you reduce the potential for mold and mildew growth.  Moisture buildups can lead to mold growth, which can cause health issues.  Persistent moisture can eventually cause expensive structural damage in the form of rot.

The SMARTBATT™ innovative MoistureSense™ facing, unlike traditional polyethylene vapor barriers, is a smart vapor retarder. It blocks moisture when humidity is low in the cavity yet increases its permeability when humidity is high to let moisture escape.

Managing moisture within the wall is critical to help mitigate the dangers of mold and mildew growth. Learn how CertainTeed's SMART Vapor Retarders with MoistureSense™ Technology work and are a revolutionary solution to combat these issues

SmartBatt™ Creates Unparalleled Airtightness & Moisture Management

Watch how FineHomebuilding uses SmartBatt to create a superior airtight envelope without having to sacrifice moisture management. By taping the seams during the installation process, SmartBatt can be used as a continuous air barrier and has been 3rd party verified to achieve 1.6 ACH50 before either the drywall or exterior barrier were installed which helped get the ProHOME down to an ultimate 0.4 ACH50. This was all achieved without having to compromise on moisture management because SmartBatt has an integrated Smart Vapor Retarder that intelligently adapts its permeability to ambient conditions, helping to keep walls dry year round.

Low Humidity

Remains mosture tight in winter when humidity in the cavity is low.

High Humidity

Increases permeability in summer to let moisture escape when needed.
