WALL SYSTEM
Insulated Wall System
In order to meet the energy efficiency requirements for dwelling structures by the National and British Columbia Building Code, the exterior walls need to have additional insulation.
British Columbia has several climate zones (website: what is my climate zone). Each climate zone has different energy efficiency requirements.
Reference: BC Building Code, Part 9: housing and small buildings, Section 9.36:energy efficiency.
How It’s Done
The insulated wall’s thickness is determined by the climate zone where the building site is located, and the requirements of the local building authority.
Once the cabin is at lock up 2×4, 2×6 or 2×8 studs are fastened to the exterior log walls, spaced at 24″ with 4″ log screws or larger. Batt insulation is added between the studs, then the wall in covered with vapor barrier for damp proofing. The wall finish is with 1×6-1/4″ tongue & groove (T&G) spruce boards to match the log wall. The interior walls remain as the single 3-1/8″ x 6-1/4″ milled log wall.
