Rubber mats — vapourproof insulation for air conditioning and refrigeration

Rubber mats are flexible insulation from closed cell foam (FEF). The built-in vapour-tight barrier prevents the condensation of water vapour on cold surfaces, making the material suitable for freon, ice water, air conditioning ducts and cold water pipes. The offer includes mats in rolls – self-adhesive and glue-free, black and aluminium cladding.

Technical parameters

• heat conduction factor: approx. 0,033–0.036 W/(m·K) at 0 °C,
• Water vapour diffusion resistance μ: ≥ 5,000
• operating temperature range: approx. −50 °C to +105 °C,
• reaction to fire: BL-s3,d0 / CL-s3,d0 according to EN 13501-1,
• thicknesses available: 6, 9, 13, 19, 25, 32 and 50 mm,
• closed cell structure – lack of saturation, high flexibility.

Application

Refrigeration and Freon installations, ice water pipelines, ventilation and air conditioning ducts, cold water ducts exposed to condensation, acoustic insulation of channels and tanks. Larger thickness mats are also used on warm installations up to +105 °C.

How to Choose Thickness

The thickness for cold installations is selected from the non-condensing condition – the factor temperature, temperature and relative humidity of the environment determine. In practice: freon pipes split and multisplit 9–13 mm, ice water 19–32 mm, high humidity rooms and external routes – larger thicknesses. In warm installations, minimum thicknesses are defined by the WT Regulation.

Edit

• the surface must be clean, dry and defatted after a leak test,
• all front and longitudinal joints with rubber contact adhesive – also in adhesive mats,
• do not squeeze the material under the covers; use insulating support,
• outside the building protect UV insulation: paint coating, sheet coat or aluminium lining version.
