Image
Proper flashing around windows is especially important when the rigid foam serves as the drainage plane in the wall
Image
Image
Image
Provide flashing and sealing integrated with the air and water control layers for vents and other roof penetrations
Image
Pull the insulation and outer liner of the flex duct over the collar to come in full contact with the liner and insulation of the trunk line or fitting and tape in place
Image
R-5 XPS rigid foam exterior sheathing provides an air seal, moisture barrier, and additional insulation value.
Image
Raised ceiling duct chase installation technique
Image
Raised heel energy trusses extend past the exterior wall and are deeper at the wall allowing room for full insulation coverage over the top plate of the exterior walls.
Image
Raised heel or energy trusses allow even the corners of the attic to be well insulated; this helps to prevent ice dams in winter and keeps rooms cooler in summer.
