Frequently Asked Questions
Q1: What are the fire safety ratings of this rubber foam insulation?

The product has achieved Class 0 and Class 1 fire ratings according to BS 476 Part 6 & Part 7. It also holds certifications for UL94 and ASTM E 84, ensuring top-tier safety and performance globally.

Q2: How does the closed cell structure benefit the insulation system?

The closed cell structure creates an effective barrier against water and moisture permeability. This prevents heat transfer issues and ensures long-term thermal stability while resisting mold and fungi growth.

Q3: What thickness options are available for project customization?

We offer nominal wall thicknesses ranging from 1/4” up to 2” (6mm to 50mm) in standard lengths of either 6ft (1.83m) or 6.2ft (2m) to suit various HVAC and piping applications.

Q4: Can this insulation product be used in low-temperature environments?

Yes, the product operates efficiently in a wide temperature range from -50°C to 110°C, making it suitable for both cold piping systems and hot water lines.

Q5: Does this rubber foam insulation provide acoustic properties?

Yes, thanks to its dense structure and micro-foaming properties, it serves as an excellent acoustic insulator by damping sound vibrations and reducing structural noise transmitting through piping.

Q6: How does the material perform against weather and UV exposure?

The insulation exhibits good resistance to ozone, UV rays, and general weathering under ASTM G23 standards, maintaining its structural integrity without significant deformation.
