Insulation in your home provides resistance to heat flow and lowers your heating and cooling costs. Properly insulating your home not only reduces heating and cooling costs, but also improves comfort.
Insulation materials run the gamut from bulky fiber materials such as fiberglass, rockwool, cellulose, and natural fibers to rigid foam boards to sleek foils. Bulky materials resist conductive heat flow in a building cavity. Rigid foam boards trap air or another gas in their cells to resist conductive heat flow. Highly reflective foils in radiant barriers and reflective insulation systems reflect radiant heat away from living spaces, making them particularly useful in cooling climates. Other less common materials such as cementitious and phenolic foams and perlite are also available.
