Questions & Answers Ask a Product Question
Q:

Does the aluminum side need to face the heat source to be effective? I'm wanting to reduce the heat on the floor caused by the transmission and exhaust. I would like to use it under the carpet.

Asked by LAWRENCE on February 15, 2018

A:

Thank you for your question. The Summit 879020 Ultra Heat Barrier/Sound Deadening Mats do not have to be installed with the aluminum side facing the heat source. Please refer to our second and third product photos on our website, which show this product installed as you are wanting to do. We suggest using a wood roller such as Summit 879041 Sound Deadener Installation tool in order to get the mat completely flat for best results.

This is a great summit product. I have use this product before with great results. I am using it this time in a pick up cab. It provides noise reduction as well as an insulation value. I would recommend this product to any body who wants to quiet the inside of their ride. It is a good price and easy to install.

Great Value.

I did the entire interior of a classic car. It was easy to cut and install. The roller tool was needed and useful. This product makes a HUGE difference in sound levels. I installed it on the underside of the roof (example) and the roof panel went from a "boing" to a dull "thump" when I tap it with my knuckles. I don't know about how well it insulates as the car is not finished hasn't been outside yet. A lot less expensive than recognized name brands. ...read more

These mats were of a high quality and appear to be very durable. They were much less expensive than other comparable product. Installation was quite easy after I got the hang of it. I will be buying more in the very near future.
