COMPLETE VEHICLE CUSTOM INSULATION KIT POLYMER BLACK BACKING SILVER

The Hushmat Complete Vehicle Insulation Kit 61714 is a comprehensive solution designed to insulate 100% of your vehicle's firewall, floor, doors, roof, and trunk. It effectively reduces aftermarket engine, exhaust drone, road noise, and vibration, while also mitigating heat transfer from the engine, headers, exhaust, and catalytic converter into the vehicle's interior. This single, lightweight, USA-made material (HushMat Ultra) enhances comfort by making the interior significantly cooler in summer and warmer in winter, improving the efficiency of the HVAC system by over 40% (independent study). It also reduces noise levels by up to 15 decibels, creating a quieter cabin for conversations and music. HushMat is known for its ease of installation, featuring a super flexible peel-and-stick application that requires no surface preparation, even in harsh climates. It is specifically packaged for each vehicle to provide complete coverage without the need for cutting or puzzle-piecing. HushMat Ultra is self-extinguishing and meets FMVSS 302 standards.

**Technical Specs & Materials:** The Hushmat Ultra material is 1.5mm thick, with a polymer (black) and backing (silver) color. It has an R-Value of 7 and can withstand a bake of 1 hour at 240 degrees C with no deformation, sag, or flow. It exhibits cold flexibility, bending around a 25 mm mandrel at -30 degrees C without cracking or loss of adhesion. The material has a specific gravity of 1.47 (approx. 0.47 pounds per square foot). It meets FMVSS 302 standards for flammability, being self-extinguishing. Peel strength is tested in a 90-degree peel at a crosshead speed of 300mm per minute on a 25 mm wide test specimen.

**Installation Considerations:** The peel-and-stick application makes for easy installation, requiring no surface preparation. However, due to the comprehensive coverage of the entire vehicle (firewall, floor, doors, roof, and trunk), installation can be time-consuming, typically taking 4-8 hours. Gloves are recommended during installation to avoid cuts from the foil backing.

**Compatibility Nuances:** This kit is specifically designed for Cadillac Series 72 (1940) and Cadillac Series 75 (1938-1940) models, providing complete vehicle coverage without the need for cutting or puzzle-piecing. It is not a universal fit product and is tailored for these classic Cadillac vehicles to ensure optimal performance and ease of installation.

**Performance Context:** By reducing noise and heat, the Hushmat kit significantly improves ride comfort and can enhance the efficiency of your vehicle's HVAC system by over 40%. It also helps preserve the originality and value of classic vehicles by protecting the interior from temperature extremes and vibrations.
