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.

★

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.

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.

Frequently Asked Questions

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

This elastomeric insulation performs reliably within a temperature range of -50°C to 110°C, making it highly versatile for hot and cold systems.

Q2: Why does the closed-cell structure eliminate the need for a water vapor barrier?

The closed-cell structure restricts moisture penetration, protecting the material itself and the underlying system from corrosion under insulation (CUI) without extra barriers.

Q3: How does Microban protection enhance the insulation's performance?

Microban technology targets microorganisms directly, breaking through their cell walls to inhibit growth, replication, and overall activity, ensuring cleaner surface hygiene.

Q4: Is this insulation material safe for residential indoor spaces?

Yes, it is entirely fiber-free and formaldehyde-free. It has earned GREENGUARD Gold certification, indicating extremely low VOC emissions for safer indoor environments.

Q5: What fire safety ratings does this insulation hold?

The insulation is FM approved across all thicknesses and achieves Class 0 & Class 1 fire ratings under BS 476 testing protocols.
