Let it Rain!
Roof truss installation commenced today. The roof on this house is extremely simple because it is symmetric along both the longitudinal and transverse axes of the home.
In this design, the roof is resting on the external 2×6 wall, while the floors and the joists are resting strictly on the 2×4 inside walls. The intent of this design is to minimize, if not eliminate, any thermal bridging. Thermal bridging is created when materials that are poor thermal insulators come into contact, allowing heat to flow through the path of least thermal resistance. The roof and attic space in the case, was not part of the thermal envelop (livable space) and therefore was considered and treated as a “cold”, unconditioned space. For the purpose of minimizing thermal bridging, the roof trusses were designed to rest on the external 2×6 walls
An architectural tower element was added to provide the home with the sense of regalness and refinement that it merits. The roof overhangs are of 2.5 ft in length. They were primarily designed, based on the home’s orientation, to minimize the home’s solar heat gain on its southern exposure during the summer while allowing ample heat gain during the winter months.
Once the trusses in place, 1/2″ plywood was applied along with roof shingles.
