BXI Insulation Foam Roll vs Armacell AP Self-Adhesive Sheet Insulation

Buy the Armacell sheet for thermal jobs: ductwork, walls, pipes and HVAC lines. Its closed-cell nitrile/PVC foam gives an R-4.2 rating and a wide temperature range, and one sheet covers 12 square feet. Buy the BXI roll for sound: the egg-crate surface and 50 kg/m³ foam knock down reverb and echo in a home studio or office. The BXI is thin and small, so it is a sound treatment, not real thermal insulation. The Armacell is not a sound absorber and is not UV resistant, so keep it indoors or covered.

• Choose the BXI roll if you want to cut echo and reflections in a small room, booth or office and want peel-and-stick panels.
• Choose the Armacell sheet if you need thermal insulation for ducts, walls or equipment and want a rated R-value with a wide temperature range.
