Frequently asked

What makes microporous and aerogel insulation special? +

Microporous and aerogel insulation achieve the lowest thermal conductivity of any commercially available insulation material (as low as 0.020 W/m·K). They provide 3-5× better insulation than conventional materials at the same thickness, making them ideal for space-constrained applications where maximum thermal performance is critical.

Where is nano insulation board typically used? +

Nano and microporous insulation boards are commonly used in cement rotary kilns, steel ladles, continuous casting equipment, backup insulation behind refractory linings, battery pack thermal barriers, and aerospace applications. Their ultra-thin profile allows for significant space savings while maintaining superior thermal performance.

How durable are microporous insulation boards? +

Microporous boards require careful handling during installation due to their microporous structure. Once installed behind a protective facing or within an enclosed system, they provide decades of stable thermal performance with no degradation or settling. We provide encapsulation options for demanding industrial environments.
