Armacell supplies to the Mars plant in Pune, India

Mars India, a wholly-owned subsidiary of the leading global confectionery and food manufacturer Mars, invested €150 million in a greenfield plant to manufacture chocolates in the Indian state of Maharashtra. Armacell supplied thermal insulation and acoustic comfort solutions for the entire plant. Mars wanted its Pune plant to be completely eco-friendly and LEED Gold® certified. Suppliers had to fulfil stringent requirements. For example, the insulation material had to be rated Class 0 in terms of fire performance, offer low thermal conductivity and provide high water vapour diffusion resistance.


The insulated system’s aesthetics and mechanical protection were also important factors as the facility has open ceilings and many exposed areas. As they fulfil the necessary requirements, ArmaFlex® Class 0, Arma-Chek® Silver 350 and ArmaSound® were selected, contributing towards earning points needed for a LEED certification.

Supplied Armacell solutions to Mars plant

ArmaFlex Class 0 was installed on all chilled and hot water pipes. This high-tech material with its insulating closed-cell structure ensures low thermal conductivity and the FM-approved insulation material forms a seamless insulation barrier, reducing the risk of corrosion under insulation. The product is also highly flexible, which makes installation over complex-shaped piping fast and easy.


Arma-Chek Silver 350 was installed over various junctures of the ArmaFlex insulated pipes for mechanical protection and aesthetic appeal. As a complete covering system, the Arma-Chek range includes sheets, prefabricated elbows, tees and bends, as well as rivets and tape. Upon installation, the overall system looks modern and the insulated system is protected against mechanical stress and UV. ArmaSound was installed to reduce sound carriage through the ducting systems.
