Soundproofing mat for sump guard
Customer query: Sound-damping mat for sump guard
A customer approached us with the following problem:
"I am looking for a sound-damping mat for my motorcycle's sump guard. Around 4500 rpm, my engine makes a screeching sound that seems to come from the sump guard. This sound wasn't present before the sump guard was installed. Since the sump guard covers both the engine block and the exhaust, the mat needs to be quite heat-resistant. It would be helpful if the mat were self-adhesive, and as the inside of the sump guard is visible, the mat should also look a bit neat (see photos).
What is the best mat to line the inside of the sump guard with?"


The solution:
Given the circumstances, we recommend an insulation material without foam, as foam can act like a sponge in humid environments, which is not ideal. Therefore, we are looking for a compact, self-adhesive mat that offers both sound damping and heat protection.
The ideal choice is the DEI heat-resistant fiberglass mat with strong aluminum layer up to 950 °C. This mat is exactly what you need to reduce sound while keeping heat out.
Product features
- Fiberglass composite resistant to 375°C direct heat
- Adhesive layer resistant to 170°C direct heat
- Aluminum top layer for extra rigidity, resistant to 950°C
- 3 mm thick fiberglass composite layer for excellent insulation
- 4 mm total thickness – ideal for confined spaces
- Easy to form and suitable for many surfaces, including metal, aluminum, carbon fiber, and plastic
This mat is not only heat-resistant but also dampens sound due to its uneven surface, significantly reducing resonance and reflected sound.
