Does Reflective Insulation Work

Radiant barriers and reflective insulation systems work by reducing radiant heat gain.

Does reflective insulation work. To understand how insulation works it helps to understand the basics of heat flow which involves three basic mechanisms conduction convection and radiation. Dust accumulation on the reflective surface will reduce its reflective capability. Radiant barriers and reflective insulation systems work by reducing radiant heat gain. The primary function of reflective insulation is to reduce radiant heat transfer across open spaces.

This type of insulation is designed to reduce radiant heat gain. This type of insulation is designed to reduce radiant heat gain. Most common thermal insulation materials like fiberglass work by slowing conductive heat flow but reflective insulation works a little differently. How does reflective insulation work.

The layer of still air itself gives it a degree of extra insulation provided it is still otherwise it will be taking heat away through convection. How houses lose heat. Most common thermal insulation materials like fiberglass work by slowing conductive heat flow but reflective insulation works a little differently. How does reflective insulation work.

Reflective insulation reflects radiant heat and works best with a still air layer of at least 25mm 1 inch. When the sun heats a roof it s primarily the sun s radiant energy that makes the roof hot. It is most effective when kept clean and dust free. For foil insulation to be most effective the reflective surface should face an air space.

The radiant barrier should be installed in a manner to minimize dust accumulation on the reflective surface.
