Roof Sheathing With Radiant Foil Backing

This reduction can lower attic temperatures by up to 30 degrees and decrease an a c system s work load by up to 20.

Roof sheathing with radiant foil backing.

Suitable applications include sheathing in walls flooring and roof decking. Oriented strand board osb with a thin layer of low emitting aluminum foil attached to one side is a common type of thermal radiant barrier sheathing. This reflection insulation also has high mechanical properties making it perfect for load bearing applications in construction. Radiant barrier sheathing is installed on your house during the construction phase with the foil side facing down towards the living space your attic.

As an added plus weyerhaeuser rbs can even help keep non air conditioned uninsulated rooms like garages workshops and porches cooler increasing a home s usable space. The goal of a foil backed osb is to cool the air within the top layer of insulation in the attic or wall by emitting the radiant heat absorbed through the roof or exterior walls which reduces the delta t and lessens the overall energy use in a building. Can i use thermostat radiant barrier sheathing on vaulted ceilings or metal roofs. Answer yes thermostat radiant barrier sheathing can be used in both types of construction as long as you maintain a minimum 3 4 airspace for the foil surface.

However it is also used in wall systems. Foil backed osb is applied mostly in attics. It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat. Rbs radiant barrier sheathing weyerhaeuser radiant barrier sheathing rbs comes pre fabricated with a reflective foil layer that reflects up to 97 of the sun s radiant energy minimizing heat transfer through the roof and insulation to interior living spaces.
