Attic & Roof Insulation

Radiant barrier that reflects summer sun back off the roof before it heats the attic

A reflective foil layer on the underside of the roof rafters turns back radiant heat, which helps hot Tennessee attics stay cooler.

Radiant Barrier

A large share of summer attic heat comes from the sun heating the roof and radiating down. A radiant barrier is a bright metallic foil stapled to the rafters or applied as a coating, and it reflects that heat instead of letting it pass into the insulation and the ducts.

We install radiant barrier on homes across Nashville and Middle Tennessee, alone or alongside attic insulation. It works well in hot climates with ducts in the attic, and we show you how it fits with your existing ventilation and insulation.

FAQ

Common questions about radiant barrier

Does a radiant barrier replace insulation?

No. It reflects radiant heat, while insulation slows conducted heat. They work as a pair.

Does dust hurt it?

Dust on the reflective surface can reduce performance, which is why we install it facing down on the rafters.

Is it good for Tennessee winters?

Its main benefit is in summer. It does not hurt winter performance.
