Definition

radiant barriers are types of thermal and heat insulations which are made to inhibit heat transfer by thermal radiation. Thermal energy may also be transferred through transfer which include conduction or convection, however, and radiant barriers do not necessarily protect against heat transfer via conduction or convection but just heat through radiation.

Applications

radiant barriers are used in space exploration to protect spacecraft, equipment and astronauts from thermal radiation and to retain heat in extreme temperature changes in space. radiant barriers are also used in textiles to prevent cold weather injuries and hypothermia, they are used in making reflective metalized films used to control and regulate temperatures especially in very cold scenarios. radiant barriers are also used in window treatments, window glass are coated to achieve emissivity, they use laminate polyester film where at least one layer has been metalized using sputtering.Radiant Barrier Team does sputtering which involves vaporizing aluminum and passing polyester through it is regulated to control the amount of metal that ultimately coats the surface of the film.

Radiant barriers as energy savers

Radiant Barrier Team is encouraging most home owners to use radiant barriers in order to save energy and cost of minimizing heat in their homes. Homes with air-conditioning work in the attic in the hottest climate zones, could benefit the most from radiant barrier interventions, with annual utility bill savings up to 70% of the energy bills whereas homes in milder climates, could save up to 50% of the energy used if they install radiant barriers in their houses.

When radiant solar energy strikes a roof, heating the shingles, felt paper and roof sheathing by conduction, it causes the underside of the sheathing and the roof framing to radiate heat downward through the attic toward the attic floor. When a radiant barrier is placed between the roofing material and the insulation on the attic floor, much of the heat radiated from the hot roof is reflected back toward the roof and the low emissivity of the underside of the radiant barrier means that very little radiant heat is emitted downwards. This makes the top surface of the insulation cooler than it would have been without a radiant barrier and thus reduces the amount of heat that moves through the insulation into the rooms below.

The most common use for radiation barrier is as a facing for attics. For indigenous shingle roof, radiant barriers may be applied over the rafters or trusses and under the roof decking. This application method has the radiant barrier sheets draped over the trusses of rafters, creating a small air space above with the radiant barrier facing into the entire interior attic space below. radiant barriers are also installed in an existing attic by stapling another barrier to the underside of the roof rafter

To apply radiant barrier in an existing attic, a radiant barrier may be stapled to the underside of the roof rafters. In this installation it is essential that the vents be allowed to remain open to prevent moisture from being trapped in the attic. In general, a radiant barrier applied to the underside of the roof with an air space facing down to prevent the accumulation of dust, preventing the radiant barrier from conducting is usually more preferred due to the ease of installation. radiant barriers are finally installed by laying the barrier on the attic floor, this method is done during cold seasons, and this method is not highly effective since it allows some dust to accumulate over the top surface of the radiant barrier reducing its efficiency.
