Diesel heater exhaust insulation lagging plays a vital role in modern mobile and stationary heating systems. Whether used in RVs, boats, trucks, or off-grid heating applications, diesel heaters generate significant exhaust heat that, if left unprotected, can lead to safety risks, component damage, and thermal inefficiency.

At BSTFLEX, we specialize in manufacturing a complete range of diesel heater exhaust insulation lagging solutions using high-performance materials and construction methods tailored to real-world demands. Our product line includes braided fiberglass, knitted fiberglass, sewn fiberglass, and silicone-coated fiberglass lagging, each designed to withstand high temperatures while maintaining flexibility and ease of installation.

Why Diesel Heater Exhaust Insulation Lagging Matters

Without proper exhaust insulation, the metal surfaces of diesel heater exhaust pipes can reach extremely high temperatures, posing a danger to nearby wires, hoses, fuel lines, or sensitive components. Insulation lagging acts as a thermal barrier, minimizing heat radiation, improving heater efficiency, and enhancing operator safety.

Multiple Construction Methods to Suit Every Application

• Braided Fiberglass Lagging: Offers tight coverage, excellent abrasion resistance, and high flexibility, ideal for curved or moving sections of exhaust pipes.

• Knitted Fiberglass Lagging: Softer and more elastic, this version conforms easily to irregular surfaces, making it great for custom installations.

• Sewn Fiberglass Lagging: Designed with a tailored fit and stitched seams, it ensures easy wrapping around larger diameter exhaust pipes or bends.

• Silicone Coated Fiberglass Lagging: Adds moisture, oil, and chemical resistance for environments exposed to dirt, road grime, or engine oil mist.
