![]() ![]() This is laminated to one or both sides of material such as craft paper, oriented strand. In this way, radiation is the most powerful cause of heat gain and loss in any building. Radiant foil barriers consist of a highly reflective aluminium foil. Attic radiant heat barriers work by blocking or reflecting UV heat that would otherwise cause temperatures to rise in the bounded open-air space(s) in the attic. Nearly 87% of the total building heat is transferred through this radiation and is then balanced by conduction and convection. The Radiant Barrier Foil Insulation Guru helps you make your home more comfortable and efficient by showing you how to install radiant barrier foil. These invisible infrared radiant heat rays can penetrate roofs, ceilings, walls, doors, floors, and other materials. This occurrence radiates heat into the building. Arctic Shield is ideal radiant barrier to supplement the insulation already in your attic. Adding Arctic Shield in your attic helps to keep your house cooler in the summer. Your pieces will be 28 x 48 pieces that will go up and down, on top of each other. This high reflectivity and low emissivity surface will reflect out mostly 97% of radiant heat from penetrating your home/building/property - One of the most Energy Efficiency (Energy Saving) Green Building Materials, a Sustainable & Affordable Product. Radiant Barrier Foil Attic Applications Much of the heat entering your home comes through the roof. Now cut your AtticFoil to fit the rafter bays: 27-28 inches wide to go on 24 on-center rafters. One of our main products Platinum Radiant Barrier® " is Thermal Insulation/Thermal Heat Insulation that was made from the layer of 97% Pure Aluminum foil and Aluminized Metalized Film (The technology was developed by NASA, USA) to function best as under deck or roof insulation widely used in Building Construction Industries. Since thermal energy is also transferred via conduction and convection, radiant barriers are often supplemented with thermal insulation products that retard heat transfer via conduction or convection. Also, many radiant barriers are also vapor retarders because they are made of foil or Mylar so they can trap moisture rising from living spaces beneath them. Over time the dust can reduce its reflective properties. Since they work against heat and sun in warmer climates, if you live in a cooler climate you won’t get the same benefit. Surfaces that are highly reflective to long-wave (heat) energy are also low-emitting. That’s why you should never place a radiant barrier material flat, shiny side facing up on an attic floor. They’re durable: The radiant barrier is aluminum foil or another similar material so it is less likely to break down the way cellulose insulation would. Are they radiating or reflecting Both, actually. ![]() The Platinum radiant barrier is a type of building product that reflects thermal radiation and reduces heat transfer. Radiant barriers by definition have an emissivity of 0.1 or less, emitting 10 or less of the radiant energy striking them. ![]()
