It is widely anticipated that Part L Building Regulations will require windows installed in new homes from 2025 to achieve U-Values of 0.8 W / m ² K in order to meet the targets laid out in the Future Homes Standard . Most existing 70mm PVCu window systems will not be able to achieve this target .

With this in mind , Liniar has continued to invest £ millions in new product development during a time when the industry has struggled to keep up with demand for existing products . Despite external pressures , Liniar ’ s focus on innovation has resulted in the forward-thinking extrusion specialist designing a window and door system that will help fabricators and installers meet the proposed regulations with ease .

And Zero | 90 isn ’ t just for new builds . Mindful of the challenges faced by installers , Liniar ’ s 90mm system can also be retro-fitted into existing cavities without disturbing the internal finishings , thanks to an innovative rebate . The Zero | 90R window system is

ideal for every home including social housing - making it a first of its kind in the UK .

The Zero | 90 system Evolved from Liniar ’ s ground-breaking 70mm Energy- Plus system , Zero | 90 is the pinnacle of energy efficient windows and doors , boasting U-Values as low as 0.5 W / m ² K ( 0.7 with triple glazing ). The full suite of windows and doors comprises casement , tilt & turn , mock sash , French and bay window options , alongside a residential and French door , both with a choice of thresholds including Part M compliant .

The Zero | 90 system meets the triple objective of :

• Ultra-high energy efficiency

• Unparalleled sound reduction

• High sustainability credentials … all in one system .

Having designed and engineered Zero | 90 to a high environmental standard , Liniar has invested heavily in tooling and machinery to extrude its sashes with a recycled core , making the

system even more sustainable . Meeting the increasing demand for Passivhaus-capable fenestration products , Zero | 90 will help specifiers tackle the challenges of cutting carbon emissions , reducing energy consumption , and advancing sustainable construction methods using renewable and recyclable materials .

Design and Development Director Chris Armes explains , “ By significantly enhancing a building ’ s energy performance and therefore reducing its carbon footprint , Liniar ’ s latest window and door system will help developers and homeowners transition towards Net Zero living . Our calculations show that replacing standard double-glazed windows with Zero | 90 can save a UK household over £ 15,000 during the products ’ lifespan .”

He continues , “ Not only will Zero | 90 lower energy consumption and the costs associated with running heating and cooling systems , it also provides superb sound reduction , ensuring occupants enjoy all the well-being benefits that come with living in

a comfortable , quiet home . With more and more developments being built in urban areas , cutting noise is high on the list for many specifiers and Zero | 90 can reduce sound by up to 42 decibels . This means that in real terms , Zero | 90 windows actually halve noise transmission , compared to a standard double-glazed window .”

Zero | 90R for 70mm cavities

Uniquely , the Zero | 90R casement window features a clever rebated frame that can be easily retrofitted into typical UK window reveals without the need to remove existing plaster work or internal finishings such as tiles – whilst delivering all the benefits of the standard Zero | 90 window .

Not only does this reduce installation time and cost , it also makes Zero | 90R ideal for Local Authorities responsible for ensuring their existing social housing stock meets the requirements of the Government ’ s Future Homes Standard initiative .

The future of ultrahigh energy efficient windows and doors

Whether specified for a new build or a renovation project , both Zero | 90 and Zero | 90R offer environmental , economic , and well-being benefits :

• Energy savings of up to £ 15,000 * for a typical home over a normal lifespan of 35 years

• Reduced household carbon footprint , equivalent to planting over 700 trees **

• Superb noise reduction to 42 decibels – double that of a standard window – delivering a peaceful environment and improved sleep health .

Every product in the Zero | 90 range contains recycled material and is 100 % recyclable at the end of its useful lifespan .
