Radiant Barrier Roof Decking And Insulation

The osb techshield radiant barrier osb is engineered to improve energy efficiency.

Radiant barrier roof decking and insulation.

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. Radiant barriers and reflective insulation systems work by reducing radiant heat gain. Unlike insulation like fiberglass or foam neither radiant barriers nor the roofing materials hold radiant heat. It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat.

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. 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. 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. 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.

Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. Starting at one end of your attic install our ultima foil breathable radiant barrier over across attic floor joists plywood decking or existing insulation. It is meant to supplement insulation not replace it. This reflection insulation also has high mechanical properties making it perfect for load bearing applications in construction.

To be effective the reflective surface must face an air space. Myths busted and facts explained. Dust accumulation on the reflective surface will reduce its reflective capability. Radiant barriers are utilized to reduce summer heat gain in attics.

Your radiant barrier makes the roof deck sheathing invisible from the attic. But on the bright side. Installed in over 1 5 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f. A radiant barrier is designed to increase the effectiveness of your thermal envelope.
