Thermal bridging of I-joist walls
Has anyone seen any efficiency modeling data that shows the thermal performance differences due to thermal bridging in a I-joist, wall versus either a double wall or a Larsen truss? I am leaning towards building with I-joists over site built wall trusses due to simplicity of construction but I can’t seem to find any data that shows what the impact of having a full thin web in an I-joist will have on thermal bridging. In my case I’m considering building a standard 2×4 wall with Rockwool, then adding 11 7/8 I-joists to the exterior with dense pack cellulose in climate zone 6.
