Mould growth can occur when warm moist indoor air penetrates the building assembly via cracks and crevices. When this moist air comes into contact with a cool surface, it condenses and could remain there, leading to mould, mildew and structural weakness. Better moisture control can be achieved with spray foam insulation since it expands to fill the cavity, creating an air-tight seal to eliminate gaps and cracks where airborne moisture can penetrate.
How spray foam contributes to sound dampening
Since it is an air barrier, spray foam insulation can play a role in minimizing noise travelling throughout the home. Spray foam insulation contributes to sound dampening, which minimizes airborne and flanking noise in your residential builds. As a result, sounds from street traffic, barking dogs and airplane engines can be reduced.
