Frequently Asked Questions
What is the temperature range for this rubber foam insulation sheet?
This rubber foam insulation sheet works efficiently within a temperature range of -50°C to 110°C, making it suitable for both cold and hot thermal insulation applications.
What are the fire safety ratings of the insulation sheet?
It meets Class 0 and Class 1 standards according to BS 476 Part 6 & 7 test methods, offering high-standard fire-blocking capabilities.
Is the insulation material resistant to environmental factors like UV?
Yes, it features excellent resistance to ozone, UV radiation, and general weathering, complying with ASTM G23 standards.
How does the material prevent moisture build-up?
Due to its closed-cell foaming structure, the material has a very low water vapor permeability (≤0.91×10 ﹣¹³ Kg/(m.s.pa)), providing an exceptional damp-proof barrier.
Does this insulation sheet support mold or fungi growth?
No. Under the ASTM 21 test, the insulation sheet demonstrates good resistance to fungi, preventing organic growth even in humid conditions.
