Liniar’s latest launch has seen them join an elite band of window systems able to comply with the exacting Passive House standards – EnergyPlus90.
The new 90mm system is unique in that its 9-chamber profile has been designed to meet the triple challenges of thermal efficiency, noise reduction and security, while still maintaining the appearance and operation of a 70mm system.
EnergyPlus90 achieves U-values as low as 0.7 W/m²K, with Windows Energy Ratings up to A+40 for triple glazing and as low as 0.5 W/m²K with quadruple glazed windows.
Weather testing results have been particularly impressive, with a full-sized EnergyPlus90 window surpassing 3000Pa (155mph) during safety tests.
The strict conditions of PAS24:2016 have also been met, making the EnergyPlus90 window fully compliant with Part Q building regulations and achieving Secured by Design accreditation.
EnergyPlus90 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.
