Rigid Insulation Exterior Wall Detail

In its guide to insulating sheathing bsc describes the use of exterior rigid insulation board in the enclosure assembly to act not only as insulation but also as the primary sheathing and in certain areas as the drainage plane and vapor control layer for the wall assembly see exterior sheathing profiles diagram.
Rigid insulation exterior wall detail. Thermal bridging affects whole wall r value. Foamular 150 rigid foam xps insulation for exterior walls contains hundreds of millions of densely packed air cells to provide excellent thermal performance. Exterior wall basement insulation our exterior wall basement insulation can be a solution for basement wall assemblies combining continuous rigid insulation and friction fit batt insulation between the studs. In these walls continuous exterior insulation envelopes the masonry minimizing the effect of thermal bridges.
Concrete block with interior rigid insulation and stucco applicability all hygro thermal regions bsi 001. Add house wrap according to manufacturer s specifications and then install the first layer of foam to the walls. By creating continuous insulation the air and water barrier can also be installed in the exterior wall cavity with minimal interruption. This places the thermal mass inside the insulation layer.
In its guide to insulating sheathing bsc describes the use of exterior rigid insulation board in the enclosure assembly to act not only as insulation but also as the primary sheathing and in certain areas as the drainage plane and vapor control layer for the wall assembly. Simplifies installation of continuous air and water barriers. Thermalwall ph rigid eps insulation board for insulating the exterior walls of homes the advantages are plenty here panels are between 4 5 inches and 8 inches thick the exterior insulation is continuous and they can be attached with 6 inch 10 screws from 4 to 6 inches long. The top leg is taped to the wall sheathing with contractor tape.
The perfect wall the perfect wall is an environmental separator it keeps the outside out and the inside in. Industry trend to using exterior rigid insulation increased thermal value condensation resistance increased air tightness possibly increased rainwater management possibly need to develop a means to attach cladding over thick layers of exterior insulation that can meet the following requirements. Tape the seams in the osb with flashing tape to establish the primary air barrier.
