Q: How does your product compare to other insulations?

A: Our goal is to give the best possible service while offering a quality product at a reasonable price. We keep the price low on our product by not spending megabucks on advertising. We are letting our customers do our advertising for us by telling others about how our product performs.

A lot of people have asked us how our products compare with others. The most obvious difference is the price. For a fraction of the cost of others, you can completely cover the inside of the vehicle. The heat insulating qualities of our product meet or exceed those of all of the other products available. Other sound deadening products are designed to be placed in strategic locations within the vehicle. The price of these products makes covering the entire interior of the vehicle prohibitive to the budget of the average builder. Our insulation may not have as much sound deadening qualities per square inch as others, but since you can afford to cover more area for less money you will get as much sound deadening benefits.

Our insulation is constructed from a closed cell polyethylene microfoam core with a 99% pure aluminum facing on each side. The microfoam core is made up of tiny individual bubbles unlike interconnected bubbles of a sponge. That means that any liquids that come into contact with the foam core will not soak into the product. If any of the bubbles are popped, the air in those bubbles simply is combined with the space in the bubble next to it therefore retaining the closed cell structure and shape of the product.

In addition to the heat and sound deadening properties, another benefit of our product is its resistance to mold, mildew and moisture retention. Cotton or jute backed products will absorb and retain moisture which will cause expensive body panels to rust. The biggest problem while restoring an older vehicle is usually rusted out floor pans. This is caused by moisture getting trapped in the absorbent material that the factories use as heat and sound insulation under carpet.

Last but not least, our product is very lightweight. A 4'x10' roll weighs less than 2 lbs. It takes about 2 rolls for a regular cab pickup, 3 for sedans, and 4 for most wagons and vans. That means you will add less than 8 lbs when installing it in the largest vehicle.

Q: Do you ship Internationally?

A: Yes we ship to most countries with a few exceptions. To find out what the shipping to you country will be you can add the product to the shopping cart then on the right side of the shopping car window about half way down, click on "Ship outside the US". Click on your country in the drop down box and click on "Update".


Q: How thick is this insulation?

A: This insulation is approximately 3/16" thick.

Q: What is the R Value?

A: Down = 13  Horizontal = 9.6  Up = 8.1 This is better than 2" of fiberglass insulation.

Q: What is the best adhesive to use with this product?

A: The best product I have found to attach it is 3M general trim adhesive, Part #08088.

Q: What is the temperature rating for this product?

A:  Low-E brand insulation is effective up to 450 degrees.

Q: What are the sound deadening properties of the insulation?

A: Low-E has had this product tested for noise reduction using the ASTM E90-90 method. At 125 HZ the noise reduction is 23 DB. At 400 HZ the reduction is 42 DB.

Q: Will doubling up the insulation increase the insulating and sound deadening qualities?

A: Doubling the insulation does not double its effectiveness. One layer will block 98% of the radiant heat, so the second layer will not have that heat to block. Two layers will block almost all of the heat coming into the car. You will get more sound deadening benefits, however. I would suggest putting two layers on the floor and firewall where most of the heat and sound come through.

Q: You say that this is not like bubble wrap, but I can easily pop it with my fingers. Won't this product be rendered useless once the bubbles are popped?

A: The pressure per square inch you are exerting with your fingers is greater than what it would be subjected to if you were standing on it. Of course, the carpet and carpet pads on top of this will help the situation. I have had this product installed in my own 1938 Chevy Coupe for 6 years.  I have been a Long Hauler on 2 Hot Rod Power Tours and drove 3300 miles on the 2001 Power Tour. We go to other local rod runs also so this car gets plenty of use and shows no signs of compression.

Q: Do I have to place my order online?

Q: Do I have to have a PayPal account to order?

A: No. You can pay safely and securely with your credit or debit card through PayPal without having to sign up for a PayPal account.

Q: What is the best way to install this insulation?

A: Installation is fairly simple. Remove carpet or other interior pieces where the insulation  is to be installed. Make sure areas are clean. In the concave areas, such as the footwells on the floorboard, cut a piece larger that  the area to be covered. Form it into the well and make some cuts in the corners to help the insulation conform to the shape of the well.

Spray both the insulation and the floorboard with 3M general trim adhesive. Before the adhesive gets real tacky go ahead and form the material down into the footwell and continue to smooth it out as the glue dries. Putting it in a little wet will give you a chance to reposition it if you don't get it just right the first time. After the adhesive has bonded, take a sharp knife and cut off the overlapping material in the corners.

On a convex surface installation is a little simpler as the material will easily bend around these surfaces. It is usually necessary to use several small pieces on irregular shaped surfaces like the floorboard instead of trying to use one large piece. If a small area fails to get covered simply cut a small piece of the insulation to fit, and glue it in place.

If covering a large area, such as above the headliner, a large enough piece can be used to cover the entire area. It helps to have a friend handy to help hold one half of a large piece in place while you fold the other half back, apply the adhesive and attach the insulation. Once that half is bonded the other half can be done in the same manner.

Each installation is a little different due to the different shapes to be covered in each vehicle but the same basic techniques apply to all. If time and care are taken, the finished installation can be easily covered with the factory carpet or other interior materials.
