What is an Attic Radiant Barrier?
Definition and Purpose
An attic radiant barrier is a type of insulation that is installed in the attic of a building to reduce the transfer of heat. Its primary purpose is to reflect radiant heat away from the living space, keeping the attic cooler and reducing the load on the HVAC system.
How Does it Work?
Attic radiant barriers work by reflecting radiant heat. Unlike traditional insulation, which primarily slows down heat transfer through conduction and convection, a radiant barrier prevents the majority of radiant heat from entering the attic in the first place.
Radiant heat is the form of heat that travels in waves and can move through empty space. It is emitted by hot surfaces such as the sun, the roof, or even the walls of a building. When radiant heat reaches the attic, it can pass through traditional insulation materials and warm up the living space below.
A radiant barrier consists of a material that is highly reflective, typically made of aluminum. It is installed on the underside of the roof rafters or on the attic floor, facing the roof. When radiant heat strikes the barrier, it is reflected back towards the roof, preventing it from entering the attic and warming up the living space.
By reducing the amount of heat that enters the attic, a radiant barrier can help to create a more comfortable living environment and reduce the strain on the HVAC system. This can lead to energy savings and lower utility bills, particularly in hot climates where cooling costs are high.
In addition to its cooling benefits, a radiant barrier can help prevent moisture buildup in the attic. By reflecting radiant heat away, it reduces the chances of condensation forming on the underside of the roof, which can contribute to mold and mildew growth.
