SikaBarrier®

Sika understands that reducing noise in vehicles depends on many factors. Not only are baffles and dampers important, any small holes in the body can be a source of noise. With or without trim panels to cover the hole, a hole in the sheet metal allows for a significant amount of noise to enter the passenger compartment. Our SikaBarrier® products have higher densities to approximate the performance of the metal without the hole. The high density affords the highest noise reduction values with thinner parts to be applied under the trim panels with no interference.

SikaBarrier® products are either mastic pressure sensitive adhesives or specifically designed thermoplastic parts. The mastic products can be applied in any area of vehicle assembly, body, paint or trim shops; to block airborne noise from propagating through body apertures. Quickly and easily installed in trim shop, our thermoplastic products can withstand service temperatures up to 250°F.
