Radiant Barrier Roof Life

Your radiant barrier makes the roof deck sheathing invisible from the attic.

Radiant barrier roof life.

This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern. Installing a radiant barrier underneath the roof will cause the roof temperature to increase by a few degrees usually 2 10º. This may seem unbelievable since radiant barriers are sold on the fact that they will reflect 97 of radiant energy away from their 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.

The temperature of the attic space increases and that heat is transferred to the building below. Benefits of radiant barrier roof underlayment when you add a radiant material to your roof or attic you will help your home retain its conditioned air during both hot and cold seasons. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. The heat that would normally be absorbed by the insulation is now being bounced back to the roof deck and causing the roof to emit more heat upward rather than both upward and downward.

The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor. Tests have shown that installing a radiant barrier in attics generally only cause the roof and shingles to increase about 2 10 fahrenheit. Increasing summer energy consumption and cooling costs. As a result your home s interior temperature will stabilize creating improved comfort for you and your family.

Radiant barriers are utilized to reduce summer heat gain in attics. Radiantguard radiant barriers reflect block 95 97 of the radiant heat transfer and when installed in an attic space they can result in a reduction of attic temperature below the radiant barrier of up to 30 degrees.

Lowering the temperatures above living space ceilings provides a significant benefit by reducing air conditioning loads and energy usage. Roofs with radiant barrier have the potential to lower the temp at night because the radiant barrier prevented the heat loss that would typically occur from the traditional mass insulation on the attic floor rising to heat the roof. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits.
