A radiant barrier is a reflective building material that reduces radiant heat transfer. It is commonly installed in attics to reflect heat away from living spaces in summer and help reduce heat loss in winter. Radiant barriers improve energy efficiency, especially in hot climates.

How does a radiant barrier work?
It reflects radiant heat away from living spaces, reducing heat gain.

Reflective surfaces reduce radiant heat transfer.
Homes in hot climates add radiant barriers in attics to cut cooling loads and reduce air conditioning costs.
Install radiant barriers facing an open air space for maximum effectiveness.
“Install radiant barriers facing an open air space for maximum effectiveness.”
Radiant barriers reflect heat but do not reduce conductive heat flow like insulation.
Do radiant barriers replace insulation?
No. They work best as a supplement to traditional insulation.
Are radiant barriers effective in cold climates?
They help, but benefits are smaller compared to hot climates.
How long do radiant barriers last?
They can last many years if kept clean and properly installed.
