Rafter thermal bridge
WebA rafter is one of a series of sloped structural members such as wooden beams that extend from the ridge or hip to the wall plate, downslope perimeter or eave, and that are designed … WebAn alternative option is to insulate the rafter bays with a less expensive insulation like fiberglass or cellulose and to control the temperature of the roof sheathing with rigid foam onthe exterior. This approach works well in nearly any assembly, but especially on cathedral ceilings. The approach also remedies thermal-bridging issues.

WebMar 20, 2024 · Thermal bridging is categorized as either “linear,” relating to a unit of length such as a roof rafter, shelf angle, or a wall stud, or as “point,” referring to a single or repeated localized penetration of the building envelope. WebMinimize thermal bridging and reduce heat loss through the foundation Protect the damp-proof coating from damage during backfilling Provide some protection against moisture intrusion Make the foundation part of the thermal mass of the conditioned space, thereby reducing interior temperature swings
WebA thermal bridge allows heat to “short circuit” insulation. Typically, this occurs when a material of high thermal conductivity, such as steel framing or concrete, penetrates or interrupts a layer of low thermal conductivity … WebAug 1, 2006 · We installed this angle-shaped I-beam at the end of the ridge where the king-common rafters would normally go, and had a plate site-welded onto it to catch the one …
