We construct sustainable, all-natural built-out wall systems with no out-gassing or chemicals. Our built-out walls have R-Values that meet or exceed stresskin panel R-Values. A built-out wall is a wall attached to the exterior of a timber frame and insulated with rigid styrofoam, fiberglass or mineral wool.

Strawbale Enclosures are an alternative enclosure that works. Bales of straw are stacked up on top of each other and enclosed with wood framing. If you think you would like to use this insulation method, you must decide during the design process, as the roof will be designed with longer overhangs to keep water from getting into the straw. Strawbale will also affect wall thickness, windows and doors.
