Properties & Advantages

Near-still-air thermal conductivity
Very thin sections for the same performance
Rigid, easy to cut and laminate
Low heat storage, fast thermal response
Non-combustible microporous core

Typical Applications

Kiln and furnace linings
Equipment where thickness is limited
Backing behind refractory hot face
High-value, space-constrained insulation

Installation & Handling

Cut with a fine-tooth blade, laminate behind the hot face and avoid compressing the core, which would raise conductivity. Seal edges where moisture exposure is possible.

silica aerogel blanket insulation — Worth the premium when space, weight or access rules out a thicker build-up — otherwise a cheaper material will do the same job.

high temperature tape insulation — Chemically stable and low conductivity, it is the quick fix for cable fire protection and short sections of hot line.

medium temperature insulation board — Lightweight, easy to work and stable across its rated range, which keeps material cost down on equipment that never approaches refractory temperatures.

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.
