Image
Quiet ENERGY STAR-rated exhaust fans provide spot ventilation and are integrated with the home’s fresh air ventilation system.
Image
R-5 XPS rigid foam exterior sheathing provides an air seal, moisture barrier, and additional insulation value.
Image
R-6 flexible duct has 2 inches of insulation around the inner liner so a 12-inch duct requires a 16x16-inch chase
Image
Radiant barrier sheeting can be stapled to the underside of the rafters or along the inside edge of the rafters
Image
Radiant heat energy from fires decreases with distance from the flames but is intense enough at close range to cause ignition.
Image
Radiant heat from wildfires can crack windows by heating the exterior surface (#1) causing it to expand and crack when exposed to wildfire.
Image
Radiation is heat transferred through space by rays, like rays of sun that warm your skin if the rays are not blocked by a building or tree.

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.
