Burnham Insulation's blow in cellulose truck

Blown in cellulose insulation fills the wall cavities and vaulted ceiling cavities in the foyer and living room.
Note: Current minimum R-values for exterior residential walls in Washington state is R-21. Our walls are R-30 (R-5 for 1 inch of rigid polystyrene foam insulation on the outside of the exterior plywood sheathing + R-13 for 2 inches of closed spray foam insulation on the inside of the plywood + R-12 for 3.5 inches of blown-in cellulose insulation on the inside of the 2 inches of spray foam).

Unfaced R-30 fiberglass batts fill the space between the first and second floors to reduce sound transmission between the two floors.

3-inch mineral wool (rock wool) batts fill the interior wall cavities of the downstairs bedroom to reduce sound transmission to that room.

Two Burnham Insulation trucks sit outside our home; the yellow truck contains cellulose, and the white truck contains fiberglass.

11 and 1/2 inches of blown-in cellulose also surrounds the plumbing manifolds in the garage; this insulation prevents the pipes from freezing when the outside air temperatures drop below freezing and dramatically reduces the level of outside noise entering the house from the garage.

Large sheets of drywall (sheet rock) were delivered to the house because drywall installation will begin right after the insulation of the exterior walls, space between the floors, interior walls, and vaulted ceilings.
