Does Reflective Attic Insulation Work

Dust accumulation on the reflective surface will reduce its reflective capability.

Does reflective attic insulation work.

To be effective the reflective surface must face an air space. A cooler attic space means less heat moving to the cooler space below the attic. With new types of technology and approaches to keep homes comfortable it s natural to wonder if attic radiant barrier works. Reflective insulation installed in the attic ceiling helps reflect sunlight and reduce the radiant heat transfer from the underside of the roof to the other surfaces in the attic.

Air ducts in the attic. The hotter it gets the better radiant barriers work. Reflective insulation installed in the attic ceiling reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. When utilizing osb radiant barrier sheathing you can reflect up to 97 of solar radiation which translates into an attic heat reduction of up to 30 f.

The idea is that this thin material can act as a type of insulation in tight spaces where you cannot put thick fiberglass insulation. This reflective foil insulation is really a radiant barrier. Air ducts in the attic. The radiant barrier should be installed in a manner to minimize dust accumulation on the reflective surface.

Through conduction the heat travels from the roofing material to the walls of an attic. Found in major outlets such as in home depot s insulation aisle reflectix comes in tightly spooled rolls of 25 by 2 feet of shiny reflective foil look bubble wrap texture insulation in plastic bags. Reflective insulation and radiant barriers work well in warm climates particularly in homes with. Work from the perimeter of the attic toward the door or hatch so that you don t trample all over the insulation you just put in.

The hot roof material then radiates that gained heat energy onto the cooler attic surfaces. This helps keep your home cooler and more comfortable. When the sun heats a roof its radiant energy makes the roof itself hot. This helps keep your home cooler and more comfortable.

Reflective insulation systems work by reducing radiant heat gain. Reflective insulation and radiant barriers work well in warm climates particularly in homes that have. It reflects a very high percentage of heat back to its source. Always cover the tops of the ceiling joists to make sure the insulation is deep enough to reach your target r value and to prevent thermal bridging the heat loss that occurs through the wood framing.
