Radiant Barrier Insulation Flat Roof

Prevents corrosion and surface deterioration.

Radiant barrier insulation flat roof. It is meant to supplement insulation not replace it. Sunshield radiant barrier for roofs and exteriors is excellent for roof and outdoor wall applications. 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. During cold weather a radiant barrier on top of the insulation could cause water vapor to condense on the barrier s underside.

A radiant barrier is designed to increase the effectiveness of your thermal envelope. Roof systems on commercial buildings or flat roofed residences are usually quite different from most residential roofs. April 19 2019 posted in. Installing a radiant barrier underneath the roof will cause the roof temperature to increase by a few degrees usually 2 10º.

A radiant barrier works best when it is perpendicular to the radiant energy striking it. Radiant barriers are utilized to reduce summer heat gain in attics. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor. Increasing summer energy consumption and cooling costs.

Radiantguard radiant barrier foil insulation installed in an attics can reduce attic temperatures by up to 30 degrees when stapled with a staple gun to the underside of roof rafters by reflecting up to 97 of the radiant heat that strikes its surface thereby reducing heat transfer from the attic to living spaces resulting in lower utility bills. 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. This method also reduces the heat subject to attic mounted ac duct work thereby allowing them to work more efficiently. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.

The temperature of the attic space increases and that heat is transferred to the building below. 1 the existing insulation could become wet and lose some of its insulating value 2 water spots could appear on the ceiling and 3 under severe conditions the ceiling framing could rot. Condensation of large amounts of water could lead to the following problems. Radiant barrier foil insulation systems block radiant heat energy instead of absorbing it like fiberglass insulation.
