Frequently Asked Questions
Q:
What are the benefits of the self-adhesive design on this insulation sheet?
The self-adhesive feature enables faster and more reliable sealing. It simplifies the installation process, reduces manual errors, and ensures a consistent vapor barrier.
Q:
What are the standard sizes and thicknesses available?
The sheets are ideally manufactured in widths of 100cm and 120cm, with a choice of 7 different thickness options ranging from 1/4" (6mm) to 2" (50mm) to match various duct requirements.
Q:
How does the insulation material perform in fire safety tests?
It exhibits high-grade fire performance with Class 0 & Class 1 fire ratings according to BS 476 Part 6 & 7, a flame spread/smoke index of 25/50 under ASTM E 84, and a low toxicity index for enhanced safety.
Q:
Does this insulation prevent pipe corrosion?
Yes, its unique closed-cell structure serves as a robust vapor barrier (μ ≥10000) that protects pipes against environmental moisture and elements, preventing corrosion.
Q:
What is the thermal conductivity performance of this material?
It features low thermal conductivity values: ≤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, tested in compliance with ASTM C 518.
Q:
Is the insulation material resistant to environmental degradation like UV or mold?
Yes, technical tests indicate good resistance against fungi (ASTM 21), ozone (GB/T 7762-1987), as well as UV rays and general weathering (ASTM G23).
