Dynamat Dynaliner Thermal Insulator & Sound Deadening Damping 1/4" Thick 32x54"

Dynaliner is a durable, crush and tear resistant material that has the highest heat blocking properties available in a single layer material. Dynaliner isn't affected by oil and does not absorb water. Dynaliner provides acoustic isolation and excellent thermal insulation for roof, firewall, floor, quarter panels, doors and even under your hood. For best results, install Dynaliner over Dynamat.

Dynaliner is an ultra-lightweight closed cell high performance insulation. Dark gray in color, Dynaliner is available in 1/8", 1/4" and 1/2" thicknesses. Dynaliner is self-adhesive with a high-temperature acrylic adhesive. Dynaliner is optimized for temperatures from -30ºF to 200ºF (-34ºC to 94ºC) and meets both UL and FMVSS flame resistance.
