New 90mm system can achieve 0.5 W/m²K
30th May 2017

LINIAR used the FIT show to unveil EnergyPlus 90, a nine-chamber, 90mm window system said to be capable of 0.7 W/m²K, with WER up to A+40 for triple glazing and as low as 0.5 W/m²K with quadruple glazed windows.

Design & Development Director Adrian Redshaw, explained the thinking behind the new system: “With more and more developments being built on recycled brownfield land, often near busy transport links, architects are tagging acoustic criteria in addition to thermal and security specification.”

The system, which has gained Passive House certification, has also surpassed 3000Pa (155mph) during safety tests of a full-sized EnergyPlus 90 window.

Adrian continued: “The strict conditions of PAS24:2016 have also been met, making the EnergyPlus 90 window fully compliant with Part Q building regulations and, as a result, achieving Secured by Design accreditation.

“EnergyPlus 90 provides an exceptional option for commercial developers with an Rw of 42 – more than double the audible sound reduction of a standard double-glazed unit.
“Because the sight lines, frame cover and clearances are similar to the existing EnergyPlus system, the 90mm system looks and operates the same as a 70mm system, maintaining the attractive appearance and ease of use.”
Liniar also used the show to mark the 10th anniversary of the sale of its first length of its profile and launched its new 234-page Specification Guide.
