RBoard and Energy Shield insulating sheathing is recommended for hidden installations protected by a 15-minute thermal barrier: indoor and outdoor walls, ceilings, slab-on-ground, roof decks, outdoor siding, cavity walls and firewalls with at least one-hour resistance.


RBoard rigid foam boards contain polyiso, which includes a fibrous surface and is coated on both sides. It can be used beneath wood, brick, vinyl, aluminum and hard fiber panels.

Energy Shield

Energy Shield rigid foam insulating panels are made of polyiso with a fibrous surface (metal sheet, Kraft paper, metal sheet) on the top layer and a metal sheet surface on a bottom unprinted layer.
