Perhaps the most important building material in an energy efficient home is the insulation package. Without a good insulation system, one that includes caulking and sealing, many of the other energy-efficient components and equipment in the home may not perform as intended.
If your home was built before 2005, chances are it is not insulated to today's recommended insulation standards. It is highly advisable to bring your home up to the levels recommended by the US Department of Energy, to help reduce costly and ever rising heating and cooling energy bills.
Air infiltration is also a major cause for high home energy bills. Today there are many techniques to help seal off these costly leaks and alleviate these problems.
You can reduce your home's heating and cooling costs through proper insulation and air sealing techniques. These techniques will also make your home more comfortable.
