INSTALLATION OF WINDOWS

15. Should the airspace around my new windows be insulated?
Definitely! Since this area is impossible to see when the installation is complete, many installers will try to cut corners and not insulate this
space. After the new window is properly shimmed, the space between the new and old window frames should be thoroughly insulated.
There are two ways to do this. The best way is to use pieces of fiberglass insulation loosely packed around the perimeter of the window.
The other way is to use some type of expanding foam. However, with foam, it is critical that the right type of foam be used and applied in
the proper manner.
To prevent problems, it is important to use an expanding, low pressure build, closed-cell, polyurethane foam. These types of foams provide
an air barrier and act to retard moisture infiltration, as well as secure the window and reduce vibration by bonding to the window sill,
jambs, and rough opening. They serve to enhance the quality and performance of the window.
Even within this small part of the total installation, training becomes important. Many installers will use polyurethane foam indiscriminately.
