Frequently Asked Questions

Insights from Our Technical Experts

Will the exhaust insulation jacket age after long-term use?

Yes, exhaust insulation jackets can age due to prolonged exposure to high temperatures, moisture, and vibration. However, our basalt and fiberglass materials are engineered for long service life, typically lasting 5+ years under normal conditions.

How much can a muffler heat shield reduce surface temperature?

A properly installed heat shield can reduce surface temperature by 30% to 60%, depending on material, design, and ambient conditions. Our multi-layer shields achieve up to 200°C reduction.

What parameters should I consider when purchasing a muffler insulation jacket?

Key factors include operating temperature, thickness, density, fire rating, noise reduction level (NRR), and compatibility with installation space and environment.

Does basalt fiber insulation tape also have sound insulation properties?

Yes, basalt fiber has excellent sound absorption characteristics in addition to its thermal insulation performance, making it ideal for combined noise and heat control.

Can you customize heat shields for specific engine models?

Absolutely. We offer full customization — from CAD design to prototyping and mass production — for OEMs and aftermarket clients.
