The Langley passive house is a raft slab foundation with rigid insulation throughout. This wraps up the exterior foundation wall and becomes semi-rigid mineral wool.

The roof is insulated with blown in batt insulation. The house has a continuous blanket of insulation around it keeping it cozy and warm while reducing energy use by 90% over conventional construction.

 

Cold bridges are eliminated and minimized through special techniques so each path for energy transfer through the house is reduced. The rigid insulation at the slab is installed in two layers so the joints can be staggered.

Similarly the exterior mineral wool has two staggered layers and is only penetrated at points by special screws that are angled upwards to prevent sagging of the strapping and siding. Additional care is taken at the window and door to prevent air leakage.
