Class 1 Armaflex: Higher resistance to water vapour Transmission

Class 1 Armaflex is a CFC&HCFC free (ozone depletion potential of zero), flexible, black, closed cell, elastomeric nitrile rubber insulation providing a highly efficient method of controlling condensation and insulating against both heat loss and heat gain. Over 50 years practical experience combined with intensive and ongoing research and development make Class 1 Armaflex the preferred choice. Class 1 Armaflex is particularly suitable for insulating pipework for condensation control. It can be used on chilled water lines, air conditioning ductwork and refrigerated pipework and can also be used with heating systems and hot and cold water services. Class 1 Armaflex is dust free, fibrefree, CFC and HCFC free (ozone depletion potential of zero ). It is available in a wide range of sizes.

Fire Performance: Class 1 Armaflex has an excellent fire safety performance achieving Class 1 to BS476 Part 7 1997. Water Vapour Resistance Factor: Class 1 Armaflex has closed cell structure, which is a 'built-in' vapour barrier with a very high resistance to water vapour transmission. The high µ Factor enhances the product's resistance to water vapour, enabling the insulation material tom aintaina higher level of efficiency. Engineered Wall Thickness: The engineered wall concept provides a constant surface temperature for a nominal wall thickness under a given set of environmental and service conditions. In practice this means that the actual wall thickness of Class 1 Armaflex is increased as the pipe size increases. A wall thickness requirement for a range of pipe sizes operating with the same line temperature in the same environment can therefore be determined by carrying out just one calculation. Ease of installation: Class 1 ARMAFLEX is a highly flexible material, making it quick and easy to install either by sleeving onto pipework as the job progresses or, if this is not possible, pre-slit lengths are available which can be snapped on to finished pipework and sealed using Armaflex 520 adhesive
