The exterior of your home is also called the envelope or shell. Insulation and air sealing work together to help maintain consistent temperatures even under extremely hot or cold conditions. We recommend adding insulation and sealing air leakage—especially in places like the attic and crawl space or basement—to reduce energy costs, improve comfort and address a range of problems from ice dams to hot or cold rooms.
