Fiberglass insulation, stapled into wall cavities, has been in use for many years. However, spray foam insulation has now become the preferred application for homeowners who want a tight, durable seal against air and moisture filtration.
But there’s even more good news about the use of spray foam insulation:
- Saves on energy bills
- Strengthens the building structure
- Acts as a sound barrier/li>
- Keeps pollen and pollutants out
Cellulose wallspray is a great option for walls, it's spray applied and gives a much better Airseal then a fiberglass batt. We use Applegate Stabilized Cellulose, which is sprayed in under high pressure with adhesive which makes for a well insulated wall.
