There are several options to insulating your attic space. Depending on the type of home you have.Below are some of the options:
- Spray foam
- Loose-fill Fiberglass
Spray Foam (Roof Deck)
From a performance standpoint, the best type of insulation is spray foam. There are two types; closed-cell and open-cell, aka 2-lb and ½-lb, respectively. They have insulation values of approximately R-6.5 and R-3.6 per inch, respectively. When installed properly, both types of insulation will fill all of the nooks and crannies and make for a perfect air barrier. When air can’t move through it, you have zero heat transfer through convection.
