Fiber reinforced Aluminum foil backing bonded to synthetic base with temperature resistant adhesive. This is not your basic non-woven fabric! Advanced needle punched interlocked manufacturing process makes this material flexible, dimensionally stable, with a tensile strength of 65 lbs. Will not stretch, "feather out", or curl on the corners. 100% synthetic construction means this material will not create odors or support the growth of mold and mildew.

Easy to install; flexible and drapes well to conform to curves and contours.

In addition to automotive & sound system use, this material is an excellent choice for thickening, stiffening and insulating fabric panels of luggage, packs and pouches. Unlike rubber foam, this material has no hard-to-get-rid-of solvent odors that may affect those with sensitivity to volatile organic compounds. This material is also much more flexible than foam, and will not "spring" back into shape, it has a tendency to stay in whatever shape it was last handled.

Made in America. Cut to order in One Yard increments. No refunds after order is cut. One Yard = 48 inches wide X 36 inches long (Approximately).
