Roof Attic Radiant Barrier

Unlike traditional thick layers of insulation radiant barrier is a thin reflective material.

Roof attic radiant barrier.

A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. The roof still is gaining and loosing heat. The list of uses includes crawl space radiant floor attic and walls. To understand this better consider a room with one light source in the form of an unshaded light bulb hanging in the middle of the room.

Watch this youtube video for an excellent explanation of the importance of an air gap. We take a look at how radiant barriers work the different types of radiant barriers and some of the. The radiant barrier is basically just directing the same amount of heat away from the attic and the attic insulation. A radiant barrier works best when it is perpendicular to the radiant energy striking it.

A larger air space between the radiant barrier and the attic roof essentially increases the effectiveness of the radiant barrier s efforts at reducing heat transfer. If you re searching for does attic radiant barrier work or is radiant barrier worth it this article will help. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in 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.

If the radiant barrier was not there the sun would heat the roofing materials and the heat transfer would occur into the air of the attic. Ultimately a hotter attic means more work that your attic insulation and ductwork needs to put in. A radiant barrier can lower heat transfer from attics to the building below keep the attic space cooler and lower cooling costs by up to 17 in warmer climates. This video will also help you to understand the concepts of convection conduction and.

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. Our product is easy to handle and install. A stapler tape measure utility knife straight edge and safety glasses. Radiant barriers are utilized to reduce summer heat gain in attics and help to improve the efficiency of green building envelopes.

Some studies show that radiant barriers can reduce cooling costs 5 to 10 when used in a warm sunny climate. Since our insulation is fiber free no protective garments or respirators are required. Reflectix requires only basic tools.
