Thermal insulation with improved technical properties

A new, improved formulation of Armaflex has therefore been developed to meet these obligatory European fire performance, thermal conductivity and water vapour diffusion resistance values. The new formula AF/Armaflex Class O range, manufactured in the UK, has a Euroclass Fire Rating of Bs3-d0 (the European equivalent to a Class O rating) and improved thermal conductivity performance. The water vapour diffusion resistance performance is also improved. The product is free from medium chain chlorinated paraffins (MCCP), which construction product agencies in Sweden and Norway have ruled against because of the threat they have been found to pose to marine wildlife. The new formulation is also used to manufacture the Armaflex Tuffcoat range of products, which are the AF/Armaflex Class O material laminated with a tough white or black PVC covering to protect against UV, weathering and impact damage when installed outdoors. From 2014, the Tuffcoat range includes additional pipe diameter sizes up to 89mm OD, with tube and sheet wall thicknesses of 25mm and continuous sheet rolls and self-adhesive continuous sheet options also available.

applications. The products replace the previous Class O Armaflex range, with the new AF/Armaflex Class O tube and sheet product codes now prefixed with AF-CO for ease of identification. The Construction Products Regulation introduced in 2013 means it is mandatory for Armaflex and other thermal insulation products to carry a CE Mark. The legislation sets out a harmonised European standard (hEN) for declaring the technical values of flexible elastomeric foams and new testing procedures to determine the stated performance. The obligatory technical values, as set out in the harmonised standard, must be stated by the manufacturer in a Declaration of Performance (DoP) certificate.

The new AF/Armaflex Class O brand thermal insulation, incorporating a full range of elastomeric tubes, self seal tubes, coils, tape, flat sheet, self- adhesive sheets, continuous sheet (rolls) and pre-insulated pipe supports, is now available with all the products providing the same technical values for the first time. The new range from technical insulation manufacturer Armacell is suitable for refrigeration and air conditioning, chilled water, process lines and heating and ventilation pipe and ductwork
