Exterior sheathing is sustainably harvested white pine selected for durability, moisture tolerance, environmental friendliness, and non-toxic qualities.

Vapor-barrier flanges are caulked to door and window jambs then taped to wall vapor-barrier after insulating.

Here is a typical strapped-wall with the window and band joist vapor barrier flanges visible.

New-generation sprayed cellulose insulation is sprayed in wall cavities, then scrubbed flush with the studs. Excess fill is vacuumed back into the machine and recycled.
