Design Engineering 050130 Boom Mat 32" x 54" x .75" Under-Hood Thermal Acoustic Lining (12 sq. feet)

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.

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

Perfectly worked took off turbo sound

You can configure this to any shape you have a template for.It is thick dense foam with a foil cover. I was concerned that it might not stick adequately. Not to worry .. adheres well to clean surface. I used it for under hood of an MGB. Took off 1 star as difficult to cut cleanly.... Seems to do the job though.

The Design Engineering under hood insulation mat is easy to cut, fit & install. Make paper patterns first as the mat will stick to everything trying to fit it if you don't have it cut to fit first. My hood had cross members that I had to go under with the mat so it was a little more difficult to install. But it turned out real nice. I got the silver colored mat, didn't know there was a black mat that I could have got at the time. Silver should reflect the engine heat better than the black would. I would recommend this product to anyone thinking about replacing the hood insulation on their car.

Good stuff for the price. Used this on my 2002 Sequoia to dampen the engine noise just a bit. The product is exactly as pictured. Stick on one side and foil mesh on the other. My engine doesn't have a foam insulated cover like it's fancier Land Cruiser and Lexus cousins, so there is a bit of noise transmitted into the cab. This muffled it a bit which is exactly what I was after. More on the firewall might help too. Things to know. Edges are exposed foam, so a heat resistant tape is a good idea. I bought a roll that was suggested by amazon. This prevents the foam from soaking up water like a sponge. Initially I was disappointed that they didn't seal the edges of this boom mat, but I got past that. After all, you probably will have to cut and trim it anyway to fit your particular hood. For what it's worth though, it fit perfectly under the hood of a 2002 Toyota Sequoia. No trimming required.

Ordered this to finish a job lining a boat I/O engine compartment with FatMat as FatMat was out of stock. Received with approximately 5-6 inches of the backing paper torn off two corners exposing the adhesive. Adhesive was not as good as FatMat. Material is not as flexible as FatMat. Product was acceptable but overall preferred the FatMat product.

I ordered the mat, tape and roller. Tape and roller delivered, the mat took a while. I used the mat on an RV engine cover with Gorilla Glue spray adhesive. Seems to hold OK. The reduction in engine noise and heat is substantial.
