Frequently Asked Questions

QWhat is the operating temperature range for this insulation?

This insulation material is engineered to perform reliably across a temperature range of -50°C to 110°C, tested in compliance with the GB/T 17794-1999 standard.

QWhat thicknesses and roll sizes are available?

The insulation is available in various thicknesses ranging from 1/4" (6mm) to 2" (50mm). Roll widths come in standard 1m, 1.2m, and 1.5m configurations, with lengths tailored to optimize total area coverage per roll.

QHow does the thermal conductivity vary with temperature?

Thermal conductivity remains exceptionally low to prevent heat transfer: ≤0.030 W/(m.k) at -20°C, ≤0.032 W/(m.k) at 0°C, and ≤0.036 W/(m.k) at 40°C, measured using the ASTM C 518 standard.

QWhat fire safety standards does this material meet?

The material achieves a Class 0 & Class 1 fire rating (BS 476 Part 6 & 7). Additionally, it complies with the ASTM E 84 standard with a Flame Spread / Smoke Developed Index of 25/50, and has an Oxygen Index of ≥36.

QDoes the material resist moisture and weathering?

Yes, it features excellent resistance to water vapor (permeability ≤0.91×10⁻¹³ Kg/(m.s.pa), μ ≥10000) and displays high resilience to environmental factors including fungi (ASTM 21), ozone (GB/T 7762-1987), and UV/weather exposure (ASTM G23).
