Passivhaus 90mm Window System

EnergyPlus90 is a Passivhaus certified system, developed by Liniar and launched in 2017. A 90mm lead-free uPVC window and door system, EnergyPlus90 looks and acts as a 70mm system and is ideal for the commercial market.  With triple benefits of Passive House thermal efficiency, PAS24 security and fantastic noise reduction capability (acoustic values as high as 42 decibels), EnergyPlus 90 UPVC windows and doors are available from Liniar fabricators all over the UK.

Thermal Efficiency

EnergyPlus90 from Liniar now joins an elite band of window systems able to comply with the exacting PassivHaus standards.

Many other systems feature messy and time-consuming foam-filled cavities to meet the requirements.

EnergyPlus90 is unique in that its 9-chamber profile – 3 more chambers than Liniar EnergyPlus – has been designed to meet the triple challenges of thermal efficiency, noise reduction and security, achieving U-values as low as 0.5!

Weather Testing

Weather testing carried out on a full-sized EnergyPlus90 window has surpassed BS6375 requirements and achieved the highest results possible.

Water class E1050 (91mph) 1050Pa

Deflection load – 2000Pa (126mph)

Safety load – 3000Pa (155mph)

Acoustic Testing

With acoustic values as high as 42 decibels, EnergyPlus90 offers a unique proposition for commercial developers. Note that a standard Liniar double glazed unit achieves noise reduction of 33 decibels.

Glazing Options

Most uPVC window systems are limited to 40mm glazing options – however EnergyPlus90 offers triple glazing as standard, in a choice of 48mm or 56mm units.

There are almost endless combinations of glazing available for EnergyPlus90, to suit every type of  installation. Triple glazed units can incorporate Pilkingtons Optiphon or Saint Gobain Stadip Silence acoustic glass if high acoustic values are important to your customer.
