SHT 01 — Radiant barrier for metal roofs
Insulation built for metal roofs.
Low-E ThermaSheet reflects Florida heat before it reaches your living space. It also helps control the condensation drip that bare metal panels create.

SHT 02 — Why it goes under a metal roof
Metal roof insulation does two jobs in Florida.
01
It reflects radiant heat.
The foil face turns summer heat back at the panel instead of letting it soak into your attic.
02
It helps control condensation drip.
Metal panels sweat when Florida nights cool down. ThermaSheet helps keep that moisture off your deck and framing.

SHT 04 — Where the savings come from
A cooler attic is a cheaper attic to cool.
Reflecting radiant heat before it reaches the attic can help your air conditioning run less through a Florida summer. We include the full spec sheet with every quote.

SHT 05 — Questions we get every week
Metal roof insulation questions.
Does a metal roof need insulation underneath?
In Florida it can earn its keep twice. Installed with an air space next to the foil, it reflects radiant heat and helps control the condensation that forms under metal panels.
Does ThermaSheet replace my underlayment?
No. RPS supplies ThermaSheet as a radiant barrier. Your roof still needs the underlayment that its permit requires.
How does ThermaSheet fit into my roof?
It works as a radiant barrier under your metal panels. Our team will walk you through where it goes in your specific roof assembly.
How much can ThermaSheet lower my cooling costs?
Savings depend on your roof, attic and air conditioning, so we do not publish a single number. A properly installed radiant barrier, with an air space next to the foil, may reduce cooling demand. Savings vary.
