Rigid Insulation Exterior Wall Detail

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.

Rigid insulation exterior wall detail.

The perfect wall the perfect wall is an environmental separator it keeps the outside out and the inside in. Thermal bridging affects whole wall r value. Exterior insulated masonry walls are walls that have insulation on the exterior side of the thermal mass. It s also virtually impervious to moisture preventing loss of r value due to moisture penetration.

This places the thermal mass inside the insulation layer. In these walls continuous exterior insulation envelopes the masonry minimizing the effect of thermal bridges. 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. Simplifies installation of continuous air and water barriers.

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. Tape the seams in the osb with flashing tape to establish the primary air barrier. 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. The wall assembly can control rain air vapor and heat.

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. Add house wrap according to manufacturer s specifications and then install the first layer of foam to the walls. Foamular 150 rigid foam xps insulation for exterior walls contains hundreds of millions of densely packed air cells to provide excellent thermal performance.
