Sound deadening insulation


Koolmat is a high temperature composite sounds deadening insulation, consisting of densified silicone shaped into a fiberglass mat. No adhesive is used meaning that it will not separate, tear and is difficult to puncture. We stock several sound deadening kits cut and shaped specifically for British cars.

In addition to the thermal performance Koolmat can reduce noise by as much as 23 decibels. For British cars especially, you will notice a significant reduction in road and engine noise.
