* Don't compress insulation to fit: it needs air space to work effectively.

* Prevent heat loss hear by adding a second layer of insulation over the joists = Attic Blanket

The basic idea is to use the appropriate insulation within your home to save on heating and cooling costs. There are easy fixes and many new technologies in insulation that will prevent thermal loss year round. The expenses might seem high but will be able to pay for themselves in years and create a more energy efficient environment. This article will discuss the different options and procedures available.
