Siding acts as a shield for the foundation of your home, protecting it from the outdoor elements. It helps preserve your home's insulation, which is responsible for ridding the walls of insects, dirt, and moisture. If insulation is unable to fulfill its purpose, your home is at high risk for moisture buildup, mold, and mildew, leading to structural damage due to bowing or warping of the walls. Well-insulated siding can keep the heat inside your home while also keeping the cold weather out. Insulated siding is breathable, meaning it allows water vapor to escape, leading to protection from mold, rot, and mildew and contributing to healthy indoor air conditions. Aside from the many practical functions, the visual appeal of siding adds additional allure to your home.
