INSULATION – FLOORS, WALLS, CEILINGS and AIR BARRIERS
The areas between the floor joists are filled with batt insulation and the entire subfloor area is covered with a radiant air barrier. This radiant air barrier provides protection from air wash which can reduce the effectiveness of the insulation. The radiant barrier also reflects any radiant heat back into the warm floor insulated area preventing heat loss to the cooler earth at the bottom of the crawl space.

The same installation process applies to the walls and ceilings. All insulation and barriers exceed WA State building code for this area.

We are now ready for 3rd party independent verification of application and R-value prior to the installation of the sheet-rock.
