Roof Protect Chemical Services Radiant heat from the sun hits the outside of the roof and walls and is absorbed, heating the building surface. The absorbed heat radiates through the insulation and increases the temperature of a building. Even conventional glass fiber or blown – the insulation can radiate heat to varying degrees from building surfaces, including roofs and ceilings.
The radiation barrier is a building material that reflects heat radiation and reduces heat transfer. Since heat conduction and convection also transfer heat energy, radiation barriers can supplement the thermal insulation, which slows down heat transfer by conduction or convection. The installation of a radiation barrier is necessary, to combat the most important forms of heat transfer (radiation) that are not currently controlled by conventional insulation.
