Roof Radiant Heat Barrier

The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor.

Roof radiant heat barrier. Reflectix insulation has over 20 energy saving applications for reflectix insulation has over 20 energy saving applications for around the home. Increasing summer energy consumption and cooling costs. Radiant barriers are utilized to reduce summer heat gain in attics. The temperature of the attic space increases and that heat is transferred to the building below.

This means radiant barrier can increase the life of the roof shingles. This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. Radiant barrier foil insulation systems block radiant heat energy instead of absorbing it like fiberglass insulation.

Your radiant barrier makes the roof deck sheathing invisible from the attic. Radiant barrier is a highly reflective material typically made of aluminum which blocks the transfer of radiant heat by reflecting it away from its surface offering a permanent way to reduce your monthly utility costs.

But on the bright side. Our product is easy to handle and install. The list of uses includes crawl space radiant floor attic and walls. 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 works best when it is perpendicular to the radiant energy striking it. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. 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. Underneath roofing materials or in the attic this keeps the attic airspace cooler during the summer.

Installing a radiant barrier underneath the roof will cause the roof temperature to increase by a few degrees usually 2 10º.
