Insulation Application Scene

Main Applications

Rubber Foam Insulation Sheet Roll is widely used to retard heat gain and control condensation drip from chilled water and refrigeration systems. It also efficiently reduces heat flow on hot systems.

It is designed for all applications that cannot be accomplished by standard Tube Insulation. It is particularly adaptable for insulating large surfaces, pipelines, and complex shapes.

Frequently Asked Questions

What are the primary applications of the Rubber Foam Insulation Sheet Roll?
It is primarily used to control condensation and prevent heat gain in chilled water systems, refrigeration pipelines, and HVAC systems. Additionally, it helps reduce heat loss in hot water and heating systems.
How does the closed-cell structure benefit insulation?
The closed-cell structure acts as a built-in vapor barrier, offering high resistance to water absorption and moisture ingress, ensuring stable thermal performance over time.
What temperature range can this insulation sheet roll withstand?
According to the technical testing, the operating temperature range spans safely from -50°C up to 110°C, making it suitable for both cooling and heating equipment.
Is this insulation sheet fire-resistant?
Yes. The material meets Class 0 & Class 1 fire ratings according to BS 476 standards and holds multiple fire safety certifications including UL94 and ASTM parameters.
In what dimensions and thicknesses is the insulation supplied?
It is supplied in flat sheets and continuous rolls with widths ranging from 1m to 1.5m, and standard thicknesses ranging from 1/8" (3mm) to 2" (50mm).
Does this insulation provide soundproofing?
Yes, thanks to its dense elastomeric composition, it provides great acoustic insulation, effectively dampening structure-borne vibration and reducing sound transmission.
