Features display
1. Good Fire Performance

FM approved for entire range of insulation thickness. Certified to conform to safety, reliability and performance standards of various local fire safety bodies.

2. Closed-Cell Structure

Minimises moisture penetration to ensure long-term protection against corrosion under insulation. Removes the need for an additional water vapour barrier.

3. Energy Efficient

Low thermal conductivity minimizes energy losses to give long term energy savings.

Microban Protection

When microbes come into contact with the insulation surface, Microban penetrates the cell wall of the microorganism, disabling its ability to function, grow and reproduce.

4. Safer Indoor Air Quality

Fibre-free, free of formaldehyde and GREENGUARD Gold certified for low emissions of volatile organic compounds.

5. Easy-to-Install

Highly flexible elastomeric foam that can be installed quickly on irregular shapes and installations in tight spaces.

Frequently Asked Questions

Q1: What is the operating temperature range for this insulation material?

A1: This material has an operating temperature range of -50°C to 110°C, tested in compliance with the GB/T 17794-1999 standard.

Q2: How does the closed-cell structure benefit the insulation performance?

A2: The closed-cell structure minimizes moisture penetration to ensure long-term protection against corrosion under the insulation (CUI). This feature also eliminates the need for installing an additional water vapor barrier.

Q3: What are the fire safety ratings of this product?

A3: The insulation achieves Class 0 & Class 1 fire ratings (tested under BS 476 Part 6 & 7) and maintains a Flame Spread and Smoke Developed Index of 25/50 according to ASTM E 84 standards.

Q4: Does the material provide protection against mold and microbes?

A4: Yes. It features Microban protection, which disables the growth, function, and reproduction of microorganisms on the insulation surface. It also shows good fungi resistance under ASTM 21 standards.

Q5: Is this insulation product safe for indoor air quality?

A5: Absolutely. It is completely fiber-free, formaldehyde-free, and is GREENGUARD Gold certified for low emissions of volatile organic compounds (VOCs).

Q6: What is the thermal conductivity of this insulation material?

A6: According to ASTM C 518 testing, the thermal conductivity values are ≤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, ensuring high energy efficiency.
