Frequently Asked Questions
What is the standard thickness range of the insulation materials?
The standard thickness ranges from 1/4" (6mm) up to 2" (50mm), providing varied insulation levels suitable for different requirements.
What are the available width options for the rolls?
The insulation sheets are available in three standard widths: 1m, 1.2m, and 1.5m, with total roll sizes adapted to optimize installation areas.
What is the thermal conductivity rating of the material?
The thermal conductivity is rated at ≤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, following ASTM C 518 standards.
Does the insulation material offer good fire performance?
Yes, it achieves a Class 0 & Class 1 fire rating according to BS 476 Part 6 & 7 tests, and conforms to ASTM E 84 with a flame spread and smoke developed index of 25/50.
Is the insulation material resistant to environmental factors like ozone and UV?
Yes, technical tests (ASTM G23 & GB/T 7762-1987) show that the material has good resistance to ozone, UV exposure, weathering, and fungi growth.
