Walls built and raised.

First prototype wall erected.

Exterior wall installed, with thermal break Foamular spacers attached with 8” screws. Note wall studs lap onto ICF foundation 6” down covering well below rim joist level, and tamarack (weatherproof) exterior shoe board.

Mock-up of wall system designed by Tom, including drain plane airspace and window flashing.

Attaching the wall raising jig to preconstructed prone wall.  

Floating partition receiver allowing for complete insulating behind.

Open 2 stud corner allowing for complete insulating.

Front wall supported by adjustable braces.

Exterior wall studs ready to be attached to OSB sheathing, note 22.5 degree angle on top.

Studs attached to wall exterior.

Exterior wall stud system being extended below main floor on top of ICFs with additional EPS foam. Note Typar sheathing which covers EPS foam. This will prevent deterioration of underneath EPS from the exterior foaming process.

Lower section of extended stud walls are attached to ICF foundation ribs with cleats screwed into the ICF ribs.  Will be bonded in place forever by the foaming process.
