Installation Process:

There are two main methods used for installing insulation within attic walls.

1. Have a wall framed in order to provide a cavity to support insulation.
2. Use a method to fasten and support the insulation in the area. This can be done by wrapping the area with an air barrier product, or by using rigid or flexible strapping.

Method one is preferable as it provides a more consistent, durable, and uniform result.
