Radiant Barrier Roof Life

Radiant barriers are utilized to reduce summer heat gain in attics.

Radiant barrier roof life.

Your radiant barrier makes the roof deck sheathing invisible from the attic. Increasing summer energy consumption and cooling costs. Installing a radiant barrier underneath the roof will cause the roof temperature to increase by a few degrees usually 2 10º. This means radiant barrier can increase the life of the roof shingles.

Multiple studies have confirmed that a radiant barrier is a worthy addition to a home s thermal envelope. 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. April 19 2019 posted in. The temperature of the attic space increases and that heat is transferred to the building below.

A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. Radiant barrier has been shown to decrease ceiling heat gains by up to 42 in certain tests. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. But on the bright side.

A radiant barrier works best when it is perpendicular to the radiant energy striking 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. Lowering the temperatures above living space ceilings provides a significant benefit by reducing air conditioning loads and energy usage. 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.

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