The background

In 2015, the UK Government announced major plans to build 200,000 starter homes by 2020 – with close to a million homes overall within the same period. These homes are likely to be built on brownfield land in urban areas, often near busy roads and rail lines.

A study of roads in November 2016 showed that British roads are the most congested in Europe.

In addition, the building of a new high speed rail network (HS2) combined with a proposed new third runway at the already busy London Heathrow Airport are anticipated to add to the already high noise levels in urban areas throughout the UK.

Architects, developers and consumers are already asking for greater acoustic values in their window systems to help combat these increasing levels – but not at the expense of thermal efficiency or security.

PAS24:2016 and Secured by Design

A full sized whole window was fully tested to the stringent security requirements of PAS24:2016 and passed with flying colours. This means the EnergyPlus90 window is also fully compliant with Part Q building regulations – critical for the commercial and new build sectors. As a result, EnergyPlus90 has also achieved Secured by Design accreditation.

Colour options

EnergyPlus90 is available in a range of stocked colours specifically chosen for the commercial sector:

Why Choose Liniar Passivehaus Windows?

Thermally Efficient Windows

Thermal efficiency

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

Rain

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 PVCu 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.

Passivhaus

Passivehaus Logo

Early testing has resulted in Liniar EnergyPlus90 joining the ranks of a select few window products to claim Passive House certification.

Triple glazed whole window U-values for argon-filled triple glazed units are as low as 0.7 W/m²K with Window Energy Ratings up to A+40, even with laminate included.

Quadruple glazed whole window U-values are as low as 0.5 W/m²K

Passive House Doors

Resi Door

EnergyPlus90 can be used with a 68mm composite door blank and featuring a thermally broken low threshold can achieve U-values as low as 0.89 W/m2K.

EnergyPlus90 UPVC doors will be available in a range of styles, and will include composite entrance doors and French doors.
