This 1900 sq. ft. prefabricated timber frame and SIPs (Structurally Insulated Panels) home is being built in Maple Ridge BC. This included a 900 sq. ft. mezzanine level and a garage which added another 600 sq. ft.
After the foundation was in place, Tamlin’s timber trusses were re-assembled on site, and hoisted into place. The solid Douglas fir “glulaminated” timber trusses were designed with engineered steel connections which were pre-fit at the factory. The SIPs components included pre-insulated R30 wall panels, and premade R40 roof panels. These components were assembled over the timber frame structure quickly and smoothly to substantially speed up construction on site. Within about 2-3 weeks, the “shell” of the building was up, and given that this was a very custom build, with considerable structural engineering, this construction was a real success.
The owner wanted a higher energy efficient system so the house is being built with upgraded GPS (Graphite Enhanced Expandable Polystyrene) foam SIPS walls and a SIPS roof.
