Aluminium Cladding Nitrile Rubber Insulation

ArmaFlex^® Alu E

Aluminium cladding Highly flexible, fibre-free nitrile rubber insulation laminated with an embossed silver-colour foil for enhanced aesthetics and mechanical protection. The closed-cell insulation material with superior performance in fire safety and maintenance is used for the protection of HVAC ducts, especially in the cleanroom conditions of pharmaceuticals industries.

High-Performance Insulation with Aesthetic covering

The traditional Aluminium-clad insulation products have always faced an ever-existing problem of ugly dents, wrinkles and pockets. Thanks to the unique surface pattern, the ArmaFlex® Alu E cleverly disguises most of the imperfections that may occur during installation. The cladding is embossed with ArmaFlex® brand to avoid any counterfeiting which also lends an overall premium feel to the cladding. It’s a highly flexible nature further aids fast and easy installation in technical sections.

Water vapour and humidity are one of the biggest hindrances in enabling thermal insulation. With water vapour diffusion resistance (µ) of 60000, ArmaFlex® Alu E ensures that the insulating properties are retained in the most adverse conditions. Moreover, the surface can be wiped clean effortlessly which helps in keeping the fungi and microbes at bay, another prerequisite of a cleanroom application.

Insulation with Superior Fire performance         

In the unfortunate event of a fire breakout, the last thing anybody would want is the propagation of the fire to the other sections of the building. Insulation materials are mostly at the forefront and exposed to fire in its early stage. The responsibility to arrest fire propagation naturally comes to insulation.

With compliance to strict norms laid down by Building Regulations, ArmaFlex® Alu E has a big ace up its sleeve. It passes all the requirements of Class 1 as per BS476 Part 7 for surface spread of flame and Class 0 as per BS476 Part 6 and meets Fire category as per 1991 Building Regulations (England & Wales) and the Building Standards (Scotland) Regulations 1990. ArmaFlex® Alu E is a non-fibrous, non-itchy, easy-to-clean product. Hence, there is no probability of air contamination due to degradation of the insulation material over a period of time.

Clean Room Application in Demand!

Clean rooms are one of the most demanding applications in the Pharmaceuticals industry when it comes to insulation. Hygiene becomes the most important aspect of cleanroom application. The ducts and pipes are visible and hence should be easy to clean and aesthetically appealing. They should not retain any moisture and prohibit any possibility of microbial growth, and of course, conserve energy with minimum heat loss/gain. with the same idea in focus, Armacell has developed their 3 innovative products - ArmaFlex® Alu with simple aluminium cladding, ArmaFlex® Alu E with premium aluminium embossed cladding and Arma-Chek® GC with Glass cloth cladding
