Radiant Barrier Roof Decking And Insulation

Radiant barriers and reflective insulation systems work by reducing radiant heat gain.

Radiant barrier roof decking and insulation.

By reducing the amount of radiant heat reaching the insulation in your attic the insulation remains cooler and is able to keep your home more comfortable. Use a stick 1 4 furring strip with nail in the end works well to help push the barrier into the tight spaces of your attic. To be effective the reflective surface must face an air space. Installed in over 1 5 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f.

As the original 1 brand of radiant barrier sheathing lp techshield panels vaporvents technology prevents moisture buildup during and after construction while blocking up to 97 of radiant heat in roof panels. The osb techshield radiant barrier osb is engineered to improve energy efficiency. But on the bright side. This reflection insulation also has high mechanical properties making it perfect for load bearing applications in construction.

Radiant barrier under metal and tile roofs the radiant barrier acts as your first line of defense against radiant heat and the foam closed attic acts as the second line of defense against conductive heat flow. The radiant barrier reflects 95 of the radiant heat back to the roofing materials which then emits over 90 of the heat out the roof almost instantly. Unlike insulation like fiberglass or foam neither radiant barriers nor the roofing materials hold radiant heat. Myths busted and facts explained.

Dust accumulation on the reflective surface will reduce its reflective capability. Your radiant barrier makes the roof deck sheathing invisible from the attic. Radiant barriers are utilized to reduce summer heat gain in attics. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits.

It is meant to supplement insulation not replace it. Attics heat up when the sun s radiant energy heats the shingles and the heat is transferred to the interior attic space through the roofing materials via conduction. Starting at one end of your attic install our ultima foil breathable radiant barrier over across attic floor joists plywood decking or existing insulation.
