New 90mm system

Liniar’s latest launch at the FIT Show saw the company join an elite band of window systems that are able to comply with the exacting Passivhaus standards – EnergyPlus 90.

The new 90mm system’s nine-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.

Liniar’s design and development director Adrian Redshaw said: “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.

“Tests have resulted in EnergyPlus 90 being awarded Passivhaus certification, achieving U-values as low as 0.7W/m²K, with Windows Energy Ratings up to A+40 for triple glazing and as low as 0.5W/m²K with quadruple glazed windows.

“The results from weather testing have been particularly impressive, with a full-sized EnergyPlus 90 window surpassing 3,000Pa (155mph) during recent safety tests.”

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