Frequently Asked Questions (FAQ)
What are the primary thermal benefits of using this Rubber Insulation Sheet?
The insulation sheet features extremely low thermal conductivity (≤0.030 at -20°C), which provides excellent energy efficiency. Its closed-cell structure locks in temperature, prevents heat loss or gain, and protects pipes and ducts from thermal fluctuations.
Does this insulation sheet resist moisture and water vapor?
Yes, the material has a closed-cell structural design and exhibits high resistance to water vapor permeability (≤0.91×10 ﹣¹³ Kg/(m.s.pa)), which effectively blocks moisture ingress and prevents the risk of corrosion under insulation.
What are the safety and environmental benefits of this material?
This rubber insulation sheet is environmentally friendly, formaldehyde-free, fiber-free, dust-free, and contains low VOCs. It is also formulated to resist mold, mildew, and fungi growth, ensuring safer indoor air quality.
What is the fire performance rating of the insulation sheet?
It achieves a Class 0 and Class 1 fire rating in compliance with BS 476 Part 6 & Part 7, and meets a 25/50 Flame Spread and Smoke Developed Index per ASTM E 84, ensuring reliable structural safety and flame retardancy.
What is the operational temperature range?
This material functions efficiently within a broad temperature scope of -50°C to 110°C, making it suitable for hot water piping, chilled systems, air ducts, and industrial refrigeration lines.
