VARA FLUID Spray product system test resulted in an air permeability value of 0.00 m³/(hm²) (±0.003) standardised for a test pressure of 50 Pa. This ready-to-use phA component is a smart fluid applied membrane that can be sprayed, providing advanced protection, allowing vapour to escape and dry the wall assembly during the whole year.
The baseline requirement for phA – the highest level of certification – is ≤0.10 @50 Pa [m3/(hm2)]. Both Partel airtight systems exceeded this significantly with a permeability result that demonstrated their unmatched effectiveness, qualified as components with the highest performance on the market in their categories of liquid-applied and self-adhesive systems.
The highest phA Class ensures designers, construction companies and building owners the best energy efficiency standard for their sustainable projects, and an increased level of certainty for the successful development of passive energy construction.
“Our ongoing commitment to reducing energy consumption in buildings and increasing building fabric durability is now sustained by the new PHI and fire certifications. Both EXOPERM MONO SA 250 and VARA FLUID Spray components have already been successfully installed in residential projects around Europe and the USA, demonstrating their real efficiency in use,” concludes Hugh Whiriskey, Director at Partel.
The two recent certifications are in addition to the certification Partel already obtained for the IZOPERM PLUS internal product system.
EXOPERM MONO SA and VARA FLUID membranes are currently available in Ireland, the UK, mainland Europe and North America.
