Acoustic Insulation

Keeping noise levels low inside the vehicle is key to achieving higher levels of passenger comfort. The SikaBaffle® and SikaSeal® family of products help improve vehicle acoustic performance by effectively sealing the car body and reducing noise transmission.

Noise Reduction from the Source

SikaBaffle® and SikaSeal® products are applied during the assembly of the body structure to later expand in the electro-deposition (E-Coat) oven to tightly seal the body cavity.



Improved Body Sealing

SikaBaffle® and SikaSeal® are also an ideal solution for preventing dust, moisture and water from getting into the passenger compartment.
