Class 1 Armaflex
Class 1 Armaflex is a CFC & HCFC free (ozone depletion potential of zero), flexible, black closed cell. It is an elastomeric NBR/PVC based insulation, providing a highly efficient method of controlling condensation and insulation against both heat loss and heat gain.
Over 50 years of practical experience combined with intensive and ongoing research and development make Class 1 Armaflex the preferred choice for chilled water lines, air conditioning, ductwork and refrigerated pipework. It can also be used with heating systems and hot water services. Class 1 Armaflex is dust free, fiber free CFC and HCFC free and available in wide range of sizes.
Class 1 Armaflex According to the thermal conductivity (K-factor) of the still air is very low of 0.024 W/m.s. It can be the ideal insulator for condensation control in cold and hot system. The perfect closed cell of Armaflex which is inside contains still air in the cell. Therefore, the thermal conductivity (K-factor) is closed to the still air inside it.

• Ease of Installation
  Class 1 Armaflex is a highly flexible material, making it quick and easy.

• Low Thermal Conductivity (Low K-factor)
  Class 1 Armaflex design for condensation control, energy saving for cold and hot system.

• High Water Vapor Resistance (High m factor)
  Class 1 Armaflex has a closed cell structure, which is a “built-in” vapor barrier with a very high resistance to water vapor transmission. The high m factor enhances the product’s resistance to water vapor, enabling the insulation material to maintain a higher level of efficiency.

• Product Durability
  Durability of Class 1 Armaflex is a high flexible material, making it quick and easy to install, either by sleeving onto pipework or if it is not possible, pre-slit lengths are available which can be snapped onto finished pipework and sealed using Adhesive 520.

• Fire Performance
  Class 1 Armaflex has an excellent fire safety performance, achieving international standards in many region worldwide.
