Roof Radiant Heat Barrier

A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.

Roof radiant heat barrier.

But on the bright side. Radiant barrier foil insulation systems block radiant heat energy instead of absorbing it like fiberglass insulation. The list of uses includes crawl space radiant floor attic and walls. This in turn prevents your house from heating up as much during the colder months this material will help prevent your home s heating from escaping through the attic and out the roof.

This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern. Underneath roofing materials or in the attic this keeps the attic airspace cooler during the summer. This means radiant barrier can increase the life of the roof shingles. Benefits of radiant barrier roof underlayment.

The temperature of the attic space increases and that heat is transferred to the building below. Increasing summer energy consumption and cooling costs. 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. Our product is easy to handle and install.

Your radiant barrier makes the roof deck sheathing invisible from the attic. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor. 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. Radiant barriers are utilized to reduce summer heat gain in attics.

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. 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.
