Reflective insulation is a type of material that reduces radiant heat transfer. Unlike traditional insulation that primarily resists conductive heat flow, reflective insulation reflects radiant heat instead of absorbing it.
When it comes to the material composition, reflective insulation typically consists of a thin layer of reflective material, such as aluminum foil, applied to a substrate material like plastic film, cardboard, or polyethylene bubbles. The reflective surface faces an air gap, which enhances its effectiveness. Reflecting radiant heat away from its surface is effective in spaces where there is a large temperature difference between the inside and outside environments.
Reflective insulation is commonly used in:
- Attics
- Walls
- Ducts
- Radiant Floor Heating
