rFOIL Reflective Insulation has been a leading manufacturer of thermal insulation for the metal building and metal roofing markets for more than 35 years. Manufactured by Covertech Inc., rFOIL has earned a reputation for quality, performance, and durability. 

rFOIL is excited to introduce rFOIL Max-NT, a new insulation product for the post-frame industry. Max-NT is the first reflective bubble insulation made with a woven scrim mesh. This provides outstanding tear-resistance, helping the insulation stay in place when stapled to wood purlins. rFOIL Max-NT is available in 4’ and 6’ widths, white/foil or foil/foil facings, and various edge tab options. 

The use of rFOIL Reflective Insulation has grown in metal buildings and metal roofing systems across North America, for its ability to control heat transfer and prevent interior condensation. 

Metal building and metal roofing systems are challenging to insulate. In the summer, heat radiates from the hot, sun-heated metal into the structure, easily raising the interior temperatures well above ambient outside air temperatures. In cold seasons, containing interior heat is a challenge as well. 

The key to rFOIL’s thermal performance is the reflective aluminum surface. Metalized aluminum film has outstanding thermal properties and reflects up to 96% of the heat that is radiating inward from the hot metal, dramatically reducing interior heat gain. Conventional mass insulations do virtually nothing to stop radiant heat gain. In cold seasons, rFOIL reduces heat loss due to its low-emittance properties, which makes it difficult for heat to radiate away from its reflective surface, thereby helping keep heat inside.

rFOIL Reflective insulation is composed of one or two highly reflective aluminum surfaces and an inner core of high-strength bubble. The bubble core reduces interior condensation by providing a thermal break between the exterior metal and the building interior. A white interior facing is also a popular option.
