Radiant Barrier Roof Decking And Insulation

This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.

Radiant barrier roof decking and insulation.

Your radiant barrier makes the roof deck sheathing invisible from the attic. Radiant barriers and reflective insulation systems work by reducing radiant heat gain. 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. Installed in over 1 5 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f.

To be effective the reflective surface must face an air space. Starting at one end of your attic install our ultima foil breathable radiant barrier over across attic floor joists plywood decking or existing insulation. 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. The osb techshield radiant barrier osb is engineered to improve energy efficiency.

Dust accumulation on the reflective surface will reduce its reflective capability. Unlike insulation like fiberglass or foam neither radiant barriers nor the roofing materials hold radiant heat. Radiant barriers are utilized to reduce summer heat gain in attics. It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat.

Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. The radiant barrier should be installed in a manner to minimize dust accumulation on the reflective surface. 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. A radiant barrier is designed to increase the effectiveness of your thermal envelope.

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. 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.
