Formaflex is a flexible closed cell thermal insulation material for condensation control in airconditioning, refrigeration and chilled water installations. It is also suitable for reducing thermal
losses in heating and plumbing systems. The combination of its technical properties – a low thermal
conductivity and a high resistance to water vapour transmission – and its competitive price makes it
a cost-effective energy-saving solution. The Formaflex range covers the majority of pipe sizes used
in these types of installations.
Low thermal Conductivity
®
FORMAFLEX has a unique closed cell structure, which offers the material a very good
and stable thermal performance through a low Lambda (λ) value.
High Water Vapour Diffusion Resistance
®
FORMAFLEX is compounded to achieve a high water vapour diffusion resistance
through its closed cell structure and outer dense skin. This helps maintaining a steady
thermal performance and a long service life.
Fire Resistance
®
FORMAFLEX is rated Group 2 under Section C3 of the NZBC; meeting the new NZBC
C/VM2 Protection from Fire requirements. It does not melt, nor drip when burning,
therefore does not cause fire transfer. Low smoke density makes it a safer option.
Environment Friendly
®
FORMAFLEX is CFC & HCFC free, fibre free, dust free and resistant to mould and fungi
growth. It has very low ODP (Ozone Depletion Potential) and GWP (Global Warming
Potential).
Ease Of installation
®
FORMAFLEX is quick and easy to install due to its high flexibility, dimensional stability
and smooth surface skin. It can be applied on pipes, ducts and tanks
