Armacell India Pvt Ltd, a company of the Armacell Group, introduces Armaflex Alu E – a flexible, fibre-free insulation material laminated with an embossed silver-colour foil. It is used for the insulation of HVAC ducts in process industries, especially clean room environments. In addition to enhanced aesthetics and fire safety performance, end-users can have greater confidence in the authenticity of the product and appreciate the reliability Armaflex Alu E offers in the long-term toward ductwork hygiene.The Heating, Ventilation and Air-conditioning (HVAC) system plays a key role in process industries, especially for cleanroom environments. This is because a well-designed HVAC system performs two key functions: •    Control of airborne particles, dust and micro-organisms, and•    Maintenance of room pressure (delta P), space moisture (relative humidity) as well as space temperature. Hence, the HVAC system is a significant energy burden as it must operate continuously with minimal, if any at all, down-time. Furthermore, the ductwork is often left exposed in an open ceiling to facilitate maintenance as cleanliness and condensation control are of utmost importance. Insulation helps to optimise the energy performance of the HVAC system. However, the wrong material could compromise indoor air quality and risk severe spread of flames in case of fire. Insulation with superior fire performance    Armaflex Alu E has been tested to meet the fire classification of Class 1 per BS476 Part 7 for the surface spread of flame as well as Class 0 per BS476 Part 6. Unlike conventional, rigid insulation material, Armaflex Alu E is also self-extinguishing and does not drip or spread flames.High performance insulation with aesthetic covering Armaflex Alu E is embossed with a uniquely designed surface pattern. This provides added mechanical protection for the insulation as well as assurance to end-users about the authenticity of the product. The aluminium foil significantly improves water vapour diffusion resistance with Armaflex Alu E offering µ = 60,000 as compared to standard Class 0 Armaflex with µ = 7,000. End-users could be even more confident about the reliable performance of the insulation product on HVAC systems, especially for pharmaceutical industries and cleanroom environments, in the control of condensation. The insulated surface can also be easily wiped clean during routine maintenance.As a flexible, fibre-free foam material, Armaflex Alu E is easy to install and will not leak fibre, ensuring that there is no compromise to the indoor air quality, even in the long-term.
