Liniar launches Zero 90 system
Liniar has unveiled Zero 90, a new, highly energy efficient 90mm system that can achieve U values as low as 0.66W/m2k with triple glazing.
An evolution of the 90mm, Passivhaus certified casement launched by Liniar in 2017, Zero 90 is the result of additional, extensive in-house development and includes options for a casement, rebated casement, mock horn and tilt n turn windows, as well as residential and French doors.
It has been designed specifically for the UK market, with Future Homes Standard regulations in mind, and as a solution for stricter Part L values that will be introduced in 2025. For new build homes these are expected to be as low as 0.8 W/m2k – according to Liniar, most existing 70mm PVC-U system will not be able to achieve this target.
The new build sector will be a key market for Zero 90 as national housebuilders look for solutions that will comply with future regulations, but Liniar has also developed a version for the retrofit market, called Zero 90R.
This features a rebated frame that can be installed into typical UK window reveals without the need to remove existing plaster work or internal finishes such as tiles. This makes it suitable for the replacement market as well as attractive to local authorities who are responsible for upgrading existing social housing stock.
Liniar adds that it has also developed suitable hardware to manage the additional weight of triple glazing as well as engineering an innovative trickle vent solution.
The casement and tilt and turn options are also officially certified as Passivhaus components, further extending the Zero 90’s appeal as a next generation PVC-U system.
The new system also delivers excellent noise reduction – Liniar claims it can reduce noise levels by as much as 42 decibels, halving the sound transmission of a standard PVC-U window – and it is also highly sustainable.
Zero 90 is a co-extruded system, which means its core is made of recycled material.
Liniar is currently offering four colour options from stock; white, black/brown, anthracite grey and rosewood, with 34 made to order foiled options also available.
There is currently no option for a flush casement, but Liniar adds that there is the potential to develop one in the future if demand is strong enough.
Liniar’s 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.
“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.”
Martin Thurley, Liniar’s group managing director, commented: “As a business we have a commitment to innovate products that will both help create energy efficient buildings and work towards our nation’s Net Zero target. We also have our own target of becoming a Net Zero manufacturer and are well on our journey towards this.
“Our aim is to provide Liniar customers with the means to stay ahead of current legislation, and the Zero 90 system will help them do just that. Even if the proposed Part L amendments are reduced, Liniar fabricators and installers will have the assurance that they can offer something better ahead of their competitors – and that’s what we always strive to achieve.”
