Radiant Barrier Roof Decking Saves Energy

A radiant barrier can reduce energy loads by up to 10 in winter based on independent studies.

Radiant barrier roof decking saves energy.

As mentioned above a radiant barrier can improve home energy efficiency. It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat. In southern climates where summers are warmer your cost savings would be closer to the 10 mark. Remember this study looked at homes in houston texas no stranger to heat.

A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. By reducing heat transfer from the living space into an unconditioned attic a properly installed radaint barrier can complement the energy saving efforts of traditional insulation. Placing a radiant barrier directly under the roof decking as illustrated above raises the attic temperature and energy consumption between 2pm and 8pm. Radiant barrier roof sheathing appears to reduce summer cooling loads by about 0 09 kwh ft of sheathing which equals about 180 kwh yr per home or 3 percent of summer cooling loads.

A radiant barrier works best when it is perpendicular to the radiant energy striking it. This means your a c bill could reduce by about 5 10. The osb techshield radiant barrier osb is engineered to improve energy efficiency. Radiant barrier roof sheathing helps to improve comfort in the building interior during the warm summer months and reduces energy costs.

Because heat always moves from hot areas to cold areas radiant barrier sheathing also prevents heat transfer from the warm interior during the cooler winter months. Here s what they found. Radiant barrier technology give your customers more energy efficiency lower cooling costs and assurance of the 20 year transferable limited warranty with the original 1 brand of radiant barrier sheathing. This reflection insulation also has high mechanical properties making it perfect for load bearing applications in construction.

In fact according to energy gov the radiant barrier can improve energy efficiency of about 5 10. Lp techshield panels patented technology blocks up to 97 of the radiant heat. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor. The reason is simple when the inside roof deck surface emissivityis lowered from 95 bare wood to a lower value the result is a hotter substrate hence the logic behind the radiant barrier.
