Thermo-Guard FR offers the best in heat and sound insulation. This lightweight, durable shield does everything: reduces sound, absorbs vibration, protects from radiant heat and provides an extra layer of insulated padding. The product features 100% polyester fiber felt that provides sound and comfort control and a high-tech foil heat barrier that blocks more than 90% of radiant heat. Thermo-Guard FR is very easy to apply and it can be trimmed to fit anywhere. Great for use in trucks, RVs, buses, cars, aircraft and homes. Available in two sizes with one or two foil sides; the polyester felt material is also available without foil. May be applied with Thermo-Tec's new Heavy-Duty Spray Adhesive.
