A radiant barrier is a reflective foil layer installed in the attic, usually under the roof rafters or decking. Instead of slowing heat like traditional insulation, it reflects the sun’s radiant heat back toward the roof before it can warm the attic. Stuff and Puff Insulation Experts installs radiant barriers for homeowners, builders and contractors, in both retrofit and new construction projects.
Why Radiant Barriers Work in Miami
- Made for hot, sunny climates. The U.S. Department of Energy notes radiant barriers are most effective in hot, sunny climates like South Florida’s.
- Cooler attic. Less heat radiating down from the roof means a cooler attic and less load on your air conditioner.
- Protects ductwork. Many Miami homes run AC ducts through the attic, where a cooler space helps keep conditioned air cool.
- Works with insulation. A radiant barrier complements attic insulation rather than replacing it.
Homes and Commercial Buildings
We install radiant barriers in existing homes and commercial buildings, and work alongside builders and contractors on new construction.
Frequently Asked Questions
Do I still need insulation if I have a radiant barrier?
Yes. A radiant barrier reflects radiant heat, while insulation slows heat moving through materials. They work best together.
Where is a radiant barrier installed?
Usually on the underside of the roof deck or rafters, with the reflective side facing an air space.
Can a radiant barrier be added to an existing home?
Yes. Radiant barriers are commonly added to existing attics as a retrofit.
Want to add insulation at the same time? See blown-in fiberglass and spray foam.
