Insulation Application

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

Rubber Foam Insulation Sheet Roll is used for all applications that cannot be accomplished by Tube Insulation. It is particularly adaptable for insulating large surfaces and complex shapes.

Frequently Asked Questions
What are the main benefits of the Rubber Foam Insulation Sheet Roll?

It offers excellent thermal and acoustic insulation, low thermal conductivity, high moisture and fire resistance, a durable closed-cell structure, and resists deformation under physical stress.

What is the thermal conductivity of this insulation material?

The material features low thermal conductivity measuring ≤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, certified under ASTM C 518 standards.

What standards and certifications does the product comply with?

The insulation sheet is certified under BS476 (Class 0 & Class 1 fire rating), UL94, CE, DIN5510, ASTM E 84, REACh, ROHS, and GB specifications.

In what sizes and dimensions is the sheet roll available?

It is available in standard flat sheets with a width of 40” (1m) and continuous rolls with widths ranging from 40” to 59” (1m to 1.5m). Nominal thicknesses range from 1/8″ up to 2″ (3mm to 50mm).

Where is the Rubber Foam Insulation Sheet Roll typically applied?
