Key Features & Advantages

Why Choose Our Insulation Material

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.

Closed-Cell Structure

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

Energy Efficient

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

Safer Indoor Air Quality

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

Easy to Install

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

🛡️

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.

Frequently Asked Questions

Common Queries Answered

What are the fire safety ratings of this insulation material?

The insulation features a Class 0 and Class 1 fire rating according to BS 476 Part 6 and 7 standards. It is FM approved across all thicknesses and achieves a 25/50 Flame Spread and Smoke Developed Index under ASTM E 84.

Does this insulation require an additional water vapor barrier?

No, the closed-cell design inherently minimizes moisture penetration, eliminating the need for an external water vapor barrier and preventing corrosion under the insulation.

What is the thermal conductivity range of this product?

The material provides excellent thermal performance with a thermal conductivity of ≤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 under ASTM C 518.

How does Microban protection work within the insulation?

Microban technology is integrated directly into the material. When microbes land on the surface, it penetrates their cell walls to disable growth and reproduction, enhancing product hygiene.

Is this product safe for indoor environments?

Yes, it is GREENGUARD Gold certified for low chemical emissions, completely fiber-free, and contains no formaldehyde, ensuring cleaner and safer indoor air quality.

What standard dimensions are available for these rolls?

Rolls are available in thicknesses from 1/4" (6mm) to 2" (50mm). Standard widths include 1m, 1.2m, and 1.5m, with varying lengths up to 30m per roll depending on thickness.
