Japanese timber frame home extension: Enclosing the frame using larsen trusses and hand tools.

Moving forward with the home extension, we added a subfloor of green pine 1.5" thick. This gave us support all around the frame to rest our Larsen trusses. These trusses are used to enclose the frame with insulation and siding while giving a useful space for things like extra insulation and utilities. On the outside of the trusses a layer of Mineral wool board insulation gives us a thermal break and can also be used as the first line against drafts. Outside this 2x2 vertical pieces are attached for a vent space, then a 1x4 layer horizontally to attach the wooden siding against. The siding will be burned white pine board and batten. A mini timber framed covered breezeway is also added in this video, which will give us insulated and covered access between the two buildings.
