High Temperature Resistant Expanded Fiberglass Fabric
Lightweight Fireproof Insulation Fabric
Expanded fiberglass fabric rated for continuous operation at 650 °C. The open-mesh structure provides thermal insulation with thermal conductivity of 0.038 W/m·K. The fabric weighs 170–195 g/m² and achieves a limiting oxygen index of 38%. The fireproof formulation is integrated during expansion, eliminating the need for topical coatings that may degrade over time.
Fireproof
LOI 38%, self-extinguishing, no melt-drip. Forms insulating char layer under flame.
High Temp
650 °C continuous, 800 °C peak. Retains flexibility after thermal cycling.
Lightweight
170–195 g/m² areal weight. 50% lighter than woven roving materials.
Flexible
Conforms to pipes, ducts, and curved surfaces without cracking or delamination.
Product Specifications
Application Fields
Also used in aerospace, marine, and power generation equipment where fire resistance and low thermal conductivity are required.
Frequently Asked Questions
Handling & Installation Guidelines
- Cut with standard shears or abrasive wheel. Edges remain stable without fraying.
- Overlap seams by 25–50 mm to maintain continuous insulation coverage.
- Secure with stainless steel wire or high-temperature tape rated above 650 °C.
- Avoid sharp creases that may reduce insulation effectiveness.
- For curved surfaces, use multiple narrower strips rather than forcing wide sections.
