An effective building envelope is a combination of insulating building materials and a reduction in air leakage. This reduction can be achieved by using taller wall sheathing panels and through effectively sealing air leaks. When determining which air leaks construction professionals should focus on, Dave Wolf from Owens Corning Science and Technology has conducted a study to see which leaks require the least effort and sealant and provide the highest returns in building envelope efficiency.
Mold is insidious and occurs where moisture collects in a home. Once you get mold in your home, it can cause cosmetic damage, stains to furniture and drywall and reduce the quality of indoor air. Worse still, it can cause rot in wood and this may compromise the structure of the home.
