An Inset Shear Panel constructed with 2x4 dimensional lumber installed into a 2x6 stud bay

Image

Lay out the rigid foam sheathing joints so they do not align with the window and door edges

Image

Rigid foam insulated sheathing placed exterior to house wrap, interior to house wrap, or take the place of the house wrap

Image

Proper flashing around windows is especially important when the rigid foam serves as the drainage plane in the wall

Case Study

Case study describing research about spray foam roof insulation and moisture management.

Retrofit an existing roof by installing rigid foam, new moisture and air control layers, new sheathing, and new cladding plus cavity insulation in the roof rafters to create an unvented attic

Image

With a quality installation, tape can last a long time

Sloped roof with cavity spray foam insulation sprayed on underside of roof deck and covered with sprayed-on thermal or ignition barrier coating.

Image

To reduce the risk of condensation on the interior of the roof sheathing in cold weather, the ratio of exterior (above-deck) insulation must be increased as a percent of total attic insulation as outside temperature decreases

Image

Wrong – Either this tape was not pressed down firmly or the surface was wet or dirty so the tape is not sticking properly even during construction.
