Our Rubber Foam Insulation could be used in schools, hospitals, government institutions and commercial spaces of all types value the long-term performance. Its moisture-resistant characteristics make it especially valuable on chilled-water and refrigeration piping where condensation might otherwise soak through fibrous types of insulations, significantly degrading their thermal performance, leaving them susceptible to fungal growth and ultimately shortening their life cycle. Moisture-resistant insulation, however, maintains its physical and thermal integrity -- for the life of the mechanical system!

Frequently Asked Questions (FAQ)

What are the primary applications for this rubber foam insulation?

It is highly recommended for schools, hospitals, government buildings, and commercial environments, particularly for protecting chilled-water lines, refrigeration piping, and HVAC/R systems where condensation control is critical.

How does the closed-cell structure benefit thermal efficiency?

The closed-cell configuration forms a built-in barrier that blocks moisture penetration and minimizes energy loss. This ensures the insulation retains its thermal integrity without needing additional external vapor barriers.

What fire and smoke performance standards does the product meet?

The insulation holds Class 0 and Class 1 fire ratings according to BS 476 Part 6 & 7. Additionally, it achieves a Flame Spread and Smoke Developed Index of 25/50 under ASTM E 84, alongside an oxygen index score of ≥36.

Does this insulation offer resistance to outdoor weather and environmental factors?

Yes. The material is formulated to resist ultraviolet (UV) radiation (tested under ASTM G23), ozone degradation (tested under GB/T 7762-1987), and biological fungal growth (tested under ASTM 21).

What dimensions and thicknesses are available?

It is manufactured in nominal thicknesses from 1/4” up to 2” (6mm to 50mm) and supplied in standard lengths of either 6ft (1.83m) or 6.2ft (2m).

Why is this foam insulation superior to traditional fibrous insulation on cold pipelines?

Fibrous insulation can soak up condensed moisture, drastically reducing its thermal insulation capacity and allowing mold to develop. Our moisture-resistant rubber foam insulation prevents moisture absorption, ensuring long-term physical stability and insulation performance.
