Thermo-Guard FR offers the best in head and sound insulation. This lightweight, durable shield does everything: reduces sound, absorbs vibration, protects from radiant heat and provides an extra layer of insulating padding. The product features 100% synthetic 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 – 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 synthetic felt material is also available without foil. May be applied with Thermo-Tec’s new Heavy Duty Spray Adhesive.
