How radiant barrier sheathing works.

Radient barrier roof sheathing.

How traditional roof sheathing works. The most effective radiant barrier sheathing is a structural roof sheathing panel which consists of an osb panel with heat reflecting foil laminated to one side. It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat. However radiant barriers can also be installed in other ways such as having it infused with your roof decking or underneath tiles.

A radiant barrier is typically stapled to the bottom truss chords against the deck sheathing. With no barrier to restrict the heat it radiates through the insulation into living spaces causing room temperatures to rise. More energy is needed to cool the house and that means higher energy costs for. Other kinds of radiant barriers combine reflective materials usually aluminium foil with materials like plastic films cardboard and kraft paper.

A radiant barrier works best when it is perpendicular to the radiant energy striking it. Radiant energy transferred through standard roof sheathing creates heat build up in the attic. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor. Upgrading the insulation to a higher r value insulating the ductwork installinga cool roof sealing any of the penetrations in the ceiling as well as.

This improved energy efficiency makes thermostat radiant barrier the ideal choice for new homes additions and renovations in warm to hot climates. Thermostat radiant barrier sheathing reflects up to 97 of the sun s radiant heat from a home s attic and can help lower attic temperatures by up to 30 f. This reflection insulation also has high mechanical properties making it perfect for load bearing applications in construction.

A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. As radiant barrier sheathing is only one component of the roof and attic space you mightconsider also. The osb techshield radiant barrier osb is engineered to improve energy efficiency. Radiant barrier applied either under the roof rafters or under the roof sheathing is probably the most common application of a radiant barrier but many homeowners shy away from it because they don t fully understand what radiant barrier is or how it works.
