A well insulated home uses less energy. That means lower heating and cooling costs and less environmental impact.
Whether it is cold air leaking in during the winter or warm air during the summer, a drafty house loses energy and is less comfortable. Insulating your home is one of the easiest and most cost-effective ways to save energy and lower your energy bill.
You can draft-proof your home by sealing the gaps and cracks with caulking and weatherstripping.
