Fire walls were made of metal or concrete, and heat-resistant walls were just thicker than others. Heat reflection entered the market as a result. Some of the incident light will be reflected, some will be absorbed by the material and some will be transmitted. Say Foylon which has the ability of reflectivity. The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it. They don't, however, reduce heat conduction like thermal.
About a third of the unwanted heat that builds up in your home comes in through the roof. This is hard to control with traditional roofing materials. For example. Solar power can be used to heat homes, particularly in cooler climates. In warmer A variety of materials absorb or reflect solar energy. Dark materials are good collectors of heat energy from sunlight. Materials have three basic optical properties: they absorb light, reflect it and transmit it.
Heat Reflection. Reflection is the opposite of absorption. Instead of being absorbed, some of the heat energy is bounced, or reflected off in the opposite direction. Textile Technologies offer a range of aluminised polyester laminated woven fabrics or felt which are used for a variety of radiant heat reflection applications. Radiant barrier is a shiny, reflective building material used to reflect heat radiation. A radiant barrier is a type of building product that reflects thermal radiation and reduces heat. A light-reflecting material as thin as aluminum foil could be used to passively cool buildings, with no electricity input.
