Fully premixed condensing boilers operate at complex temperature gradients, with alternating high heat and condensed moisture inside the combustion chamber.
Choosing stable, reliable thermal insulation & refractory components is critical for boiler efficiency, service life and safety.
Our vermiculite boards are widely adopted as insulation liners, flame baffles, combustion chamber insulation blocks and heat shields for fully premixed condensing gas boilers.
✅ A1 non-combustible grade, excellent high-temperature resistance
✅ Low thermal conductivity, minimising heat loss and helping maintain stable combustion efficiency
✅ Outstanding thermal shock resistance: handles frequent heating-cooling cycles without cracking
✅ Resistant to condensation and weak acid corrosion from flue condensate
✅ Inorganic mineral material, no harmful emissions under operating temperature
✅ Highly machinable via CNC: grooving, drilling, cutouts, curved & special non-standard profiles
✅ Adjustable thickness and density to match different boiler design requirements
✅ Low high-temperature shrinkage, consistent performance over long runtime
We support custom processing according to your drawings or samples. Whether you need small batch prototype parts or mass OEM refractory insulation components for condensing boilers, we provide one-stop thermal insulation solutions.
