This kit gives you 93 sq ft of Autoply automotive insulation cut into assorted strips, 6-in to 20-in wide by 60-in long, sized for smaller panels, pillars, doors, and trim pieces where a full 28 x 60 in sheet would be wasteful. Choose the material and thickness right on the product page - 0.5-in FiberPly, 1.0-in FiberPly, or 1.0-in DiamondPly.

FiberPly (0.5-in and 1.0-in)

FiberPly is a PET/polyester copolymer staple and bicomponent fiber insulation built for thermal and acoustic control without the itch and mess of fiberglass. It is odorless, chemical and allergen free, mildew and bacteria resistant, and fully recyclable. Every strip ships with a low-VOC acrylic, solvent-free adhesive backing under a glassine paper release liner, rated for a -40F to 250F bond range. The 0.5-in thickness carries an R2 value and the 1.0-in thickness carries an R4 value.

DiamondPly (1.0-in)

DiamondPly starts with the same proven non-woven polyester fiber core used in FiberPly, then adds a durable polypropylene spun protective layer with a diamond-pattern surface, creating a tough interior liner that resists punctures, wear, and tearing. It installs directly to vehicle walls and ceilings, eliminating the need for traditional interior paneling while still allowing access to the structure behind it, and stays flexible enough to conform to tight trim areas.

Manufacturer specifications state that Autoply FiberPly and DiamondPly materials meet Federal Motor Vehicle Safety Standard No. 302 (FMVSS 302) and Canada Motor Vehicle Safety Standards (CMVSS) for flammability, and that the material is manufactured in the USA and Buy America compliant.
