Reflective Double Foil Thermal Sound Insulation is perfect to insulation Cars , Vehicles, Boats , ect. 

Our insulation is the lightest and most effective thermal sound deadening insulation in the world! It is an EXTREMELY light-weight sound deadener & thermal barrier that creates a quiet, comfortable, and efficient interior for any vehicle. It will keep you cool by reflecting summer heat and unwanted engine, header, exhaust, but it will also keep you warm in the winter! Insulation is very flexible and easy to cut, handle, and install. It is used by professional race teams, restoration shops, car manufacturers, & many customers around the world. This insulation can be used in Any Vehicle in the entire interior including: floor pans, doors, under your carpet/seats, headliner/roof, trunk, trunk lids, firewall (interior side), & under your hood as a hood liner. Our insulation is excellent choice for use it in  SUVs, vans, RVs, limousines, campers, boats, motor homes, buses, ect.  The average four door vehicle uses 12-15sqm to do an entire install (doors, headliner, trunk, floor pan, etc.)

We have product in different sizes and thickness, so you can choose right model and use it anywhere even if there is no space for insulation.

  • Reduces unwanted sound & most vibrations
  • Effectively blocks 96% of radiant heat transfer
  • Keeps your interior cooler in the summer and warmer in the winter
  • Extremely light-weight, flexible, & crush resistant
  • Creates a mold & mildew resistant vapor barrier
  • Non-toxic & fragrance free (will not smell)
  • Non conductive for electricity (will not cause short circuit)
  • Very easy to cut, handle and install.
  • Nominal Thickness: from 2 to 6mm
  • Core Material: Polyethylene closed cell foam core
  • Minimum Installed R-Value: 1+ (Varies depending on installation & vehicle)
  • Outer Material: aluminum metallized layer covered with PET reinforced facing (non corrosive)
  • Double Sided - Aluminum on both sides
  • Mildew & Mold Resistant
  • Water resistant
  • Non-toxic
  • Non conductive for electricity

The biggest advantage to this  insulation is that it is very lightweight. For example if compare with butyl sound deadener the same are of insulation weight is 20 to 25 time higher.  That is a huge difference in weight! It will affect car performance and fuel consumption. Also our thermal sound deadener is much more effective at controlling heat compared to a butyl based product. This car insulation will help reduce your interior temperature in the summer, keep you warm in the winter, reduce engine/tunnel/console heat, reduce exhaust drone, reduce most vibrations and quiet down your interior. It will improve your vehicle by allowing your audio installation to perform more efficiently with less road noise competition and allow your climate control to work faster and more efficient while reducing your use of A/C and increase your fuel savings! If you have aftermarket headers installed then you'll most likely notice the increase in heat that is transferred into your interior and this will help eliminate that problem.

Installation Instructions for Cars: 

There is no adhesive on our car insulation but you have many options when it comes to installing it including double bounded tape, spray adhesive, foil tape, or even hook and loop fasteners. Car insulation can be double layered in areas if needed. Insulation is flexible so it is very easy to install and easily molds to different contours. Spray adhesive or double bounded tape and foil tape in combination with each other has worked best for insulation installations. Make sure your surface is clean before installation. Cut your piece to match the area you want to install it on and then spray the area with spray adhesive or use double sided adhesive tape and lay your piece down and press lightly with your hands. Continue doing this until you have the entire area you want covered. Working across your vehicle from side to side makes installation easier. Foil tape is optional to use with spray adhesive but it helps you achieve the best thermal results.

What is Reflective Insulation?

Reflective Foil Thermal Sound Insulation Provides Multiple Benefits

Insulation products consist of  Barrier Foam material laminated between layers of metalized film to provide excellent thermal resistance. The foam has many small bubble which contains an air.

Insulation is used to either contain heat for maintaining warmth, or to resist heat for maintaining cold. In many applications, radiation is the dominant mode of heat transfer.  Our reflective insulation foam is considerably more effective than conventional insulations in reducing radiant heat transfer.

Reflective foil foam reflects up to 97% of radiant energy in addition to resisting other types of heat transfer thus providing effective insulation.

High-Efficiency Performance

Thin, lightweight material provides resistance against the three types of heat flow: conduction, convection and radiation. It forms an effective barrier against moisture, air currents and vapors, while resisting fungus, insects and nesting rodents. 

Easy to Use

It’s lightweight, compact , flexible, resistant to cracking. Conforms easily to fit complex shapes. Installation is quick and simple.

Outstanding Safety, Health and Environmental Benefits

Clean, non-toxic, fire-retardant (Class A/Class 1). No special clothing or protective equipment is necessary for handling or installation.

Cost-Effective and Versatile

An economical solution for a wide range of industrial, manufacturing and consumer applications.

Typical Applications for AluFlex Reflective Insulation

  • Original equipment manufacturers (OEM)
  • Commercial and residential building
  • Insulation for food and drug shipping
  • Automotive/transportation
  • Retail/do-it-yourself
