Design Engineering Under Hood Thermal Acoustic Lining - 32" X 54" - 12 Sq Ft - Boom Mat Retail

Needed to insulate the engine compartment of my boat. Great adhesion and formed well to the shape. Reduced the noise to a more acceptable level.

Great product. I used this material to replace old insulation on the engine cover of my class A RV. It appears the original insulation was this same stuff, except it was 12 years old. After installing this insulation we traveled about 3000 miles and noted two major improvements First, the road noise was dramatically reduced, and second, the engine cover had no heat rise that we could feel. A small area that I could not reach to install the new material had a noticeable heat rise. When you install this stuff make sure the surface is clean and grease free, if you do this place it correctly the first time because it will not come off. As a side note, I covered the edges with metal tape to reduce wear on the foam. I purchased tape with the insulation, and it did not stick worth a hoot, but I used Home Depot heater duct tape and it worked great. This product is the real thing.

Used for quite truck engine, very easy to apply and did it the job.

Great product - easy install - once in place it really sticks so I hope it holds up under the heat. Here's what worked for me - I cut out a paper template for each section (My under hood has 3 sections - V12 Jag XJS) then transferred to the Pad and cut out the pad. Then I removed about a 2" strip of the paper backing covering the sticky side down the center. Once I got the pad in positioned I stuck it in place using only the 2" center part. - then I could re-position it as needed to fit the top and sides, reached underneath and pulled the sticky paper cover off from the center toward the edges and smoothed it out as I went. Before that I took the cut out pads to my upholsterer and had him sew an edging on each pad in a color that matches my car. Needed two orders for the whole hood - but I probably would need only one for my other cars. Good Luck

Does the job but small amount for very expensive price. Pictures shows the small quantity supplied. And the small engine cowling of my inboard jet boat. Not enough to do entire small engine cover I was forced to buy a second roll to complete the project. Expensive but works perfectly and has substantially made the motor noise quieter so 4 stars for me. If they supplied larger quantity or was less expensive I would have easily gave 5 stars.
