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.
Attic radiant heat barrier.
When installed properly radiant barriers can reflect up to 95 of the radiant heat off the attic.
Radiant barrier is a home insulation type that is focused on reducing summer heat gain.
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.
A cooler attic space means less heat moving to the cooler space below the attic.
The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it.
They don t however reduce heat conduction like thermal insulation materials.
It is meant to supplement insulation not replace it.
Radiant barriers are made of aluminum and designed to reflect radiant heat from the sun.
A radiant barrier is designed to increase the effectiveness of your thermal envelope.
Unlike traditional thick layers of insulation radiant barrier is a thin reflective material.
The best way i have seen to describe this effect is it s like putting your home or office under a shade tree.
This thin reflective material is designed to bounce the sun s heat away from your home instead of allowing your attic to absorb the heat and pass it into your home.
