Frequently Asked Questions
Q: What is the temperature range of the insulation material?
A: The insulation material is designed to operate safely and effectively within a temperature range of -50°C to 110°C, conforming to GB/T 17794-1999 standards.
Q: What fire rating certifications do these products carry?
A: The products are rated Class 0 & Class 1 under BS 476 Part 6 & 7. They also achieve a 25/50 Flame Spread and Smoke Developed Index (ASTM E 84) and an Oxygen Index of ≥36 (ISO 4589).
Q: Are these insulation sheets resistant to environmental factors?
A: Yes, they offer excellent resistance to ozone, fungi, and UV/weather conditions, verified by standardized tests like ASTM 21, GB/T 7762-1987, and ASTM G23.
Q: What standard dimensions and thicknesses are available?
A: Thicknesses range from 1/4" (6mm) up to 2" (50mm). Standard roll widths are available in 1m, 1.2m, and 1.5m to suit different installation requirements.
Q: How does the closed-cell structure benefit thermal performance?
A: The close and even bubble structure ensures low thermal conductivity (ranging from ≤0.030 W/(m.k) at -20°C to ≤0.036 W/(m.k) at 40°C) and prevents water vapor transmission, ensuring consistent thermal barrier efficiency.
Q: Is the material safe for indoor use and environmentally friendly?
A: Absolutely. The insulation is manufactured without formaldehyde, produces no harmful emissions, and holds REACH and RoHS compliance certificates.
