Radiant Loss In Attic

A radiant barrier in the attic helps prevent the electromagnetic transfer of heat such as from the photons in sunlight.

Radiant loss in attic.

Install radiant barriers in your attic to improve heating and cooling efficiency. Heat gain through thermal radiation can be reduced with the help of reflective insulation products like radiant. Radiant heat must be reflected with a radiant barrier. A good example of how it works is when the sun heats your home s roof and the roof radiates the heat into your attic.

Radiant barriers are utilized to reduce summer heat gain in attics and help to improve the efficiency of green building envelopes. An attic radiant barrier is made of a highly reflective material mounted on one or both sides of a substrate. There can only be one. A radiant barrier is designed to increase the effectiveness of your thermal envelope.

It is meant to supplement insulation not replace it. Installing radiant barrier under the roof decking is the preferred method versus on top of the insulation because it gives an air gap for the heat to escape to the ridge vent without creating a potential moisture problem between the radiant barrier and the attic floor. Even the insulation in your attic gives off radiant heat to the cold attic space in the winter and to the living space in the summer. Regular insulation won t stop radiant heat loss.

Thermal loss is a term used to describe how much heat exactly escapes your house. By minimizing airflow within the insulation and minimizing radiant heat loss gain from your attic radiant barrier will make your home more comfortable and more efficient creating a green energy barrier in your attic. A third type of heat transfer called thermal radiation however does not require a medium to carry the heat. Radiant barrier should always be installed to work with the soffit and ridge.

The radiant barrier for the roof you can find a wide variety of these materials that range in size color density and price however they have one thing in common and that is their high level of thermal loss. The type of radiant barrier that is laid on an attic floor will lose reflectivity quickly in arizona because of heavy dust over time. Watch the video below to learn why you need to do this to fix the biggest energy waster in your home. An attic radiant barrier system is commonly used to reduce summer heat gain and winter heat loss in new building construction or retrofit in order to improve comfort lower conditioning and heating costs and prolong the life of hvac systems.

All objects and bodies give off radiant heat. 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.
