PSI Mat-Su Valley, Alaska is your Preferred Insulation Contractor

Insulation keeps your Mat-Su Valley home warm in the winter and cool in the summer. There are several common types of insulation — fiberglass (in both batt and blown forms), cellulose, blown-in-blanket and spray foam. When correctly installed with air sealing, each type of insulation can deliver comfort and lower energy bills during Mat-Su Valley's hottest and coldest times of the year.

Insulation performance is measured by R-value — its ability to resist heat flow. Higher R-values mean more insulating power. Different R-values are recommended for walls, attics, basements and crawlspaces, depending on your area of the country.
