Combining Products

For the best results, we recommend adding two layers of insulation material inside your camper, as each product helps to tackle different noise ranges and provide different insulation properties.

You can combine the following materials to achieve the highest quality soundproofing in your vehicle:

1. Sound deadening mats:

For the first layer, you can apply this product to the vehicle’s metal body elements. The mats dampen the vibrations and low frequency noise created by these parts.

2. Closed cell foam insulation such as ST-mats:

For the second layer, you can add the ST-mat on top of the sound deadening mats. This product provides both sound and thermal insulation, and also helps to block the passage of medium and high frequency road noise inside the vehicle. In addition, this product is moisture proof which makes it an ideal finishing layer in campers as it helps to prevent condensation.
