Radiant Barrier Insulation in Your Residential Attic
The most common application in a residence is in the attic. The attic is where you loose most heat in the winter, and often the most economical way to add insulation.
Radiant Barriers
Radiant barriers are installed in homes—most commonly in attics—to reduce summer heat gain and winter heat loss, which helps lower heating and cooling costs.
Radiant Barrier: Aluminum foil installed over the air conditioned living area of the home between the interior ceiling and the roof of the home. It is typically stapled to the undersides of the sloped roof trusses. Each piece is taped and sealed.
Radiant Barrier System - A Radiant Barrier System (RBS) is a building section that includes a radiant barrier facing an air space.
Radiant barriers: A reflective insulation system that reflects radiant heat energy instead of trying to absorb it. Examples, Foil batts, aluminum paint.
Radiant barrier insulation is a reflective foil sheet installed under the roof deck like regular roof sheathing.

Air & Vapor Barriers....What Are they
Heating ...
what about radiant barrier foil spread out over attic insulation? Many companies selling it claim it can save enough money in cooling and heating cost to pay for itself if a few short years.
Reflectix is a radiant barrier wrap designed to insulate against heat loss. Unlike traditional fiberglass insulation, Reflectix is made up of foil faces on the outside that hold bubble pack between layers of polyethylene for stability.
10: Overlays and Radiant Barriers
Using an umbrella or a wide-brimmed straw hat on a hot day at the beach helps keep the sun at bay. Technology is bringing cover-ups to roofing as well.
Radiant barrier Radiant barriers are thin sheets of highly reflective material, like aluminum, which reduce heat transfer from thermal radiation across the air space between the roof and the attic floor.
If installed correctly, the reflective foil can also act as a radiant barrier that adds greater resistance to the insulating assembly. The low emissivity facings improve the thermal performance when positioned next to an un-ventilateded airspace.
It doubles as a thermal break and radiant barrier. And it's inexpensive. Rigid foam, like foil-faced technifoam or blueboard, also works. Around here, the ground under a slab remains at a constant 58 degrees F.
