The New Fully Compliant Timber Window System

Owen Dare, a founder partner of The Joinery Network and Managing Director at OT Dare Joinery Consultants, talks about how window companies can now offer fully certified timber windows and doors.
Since The Joinery Network’s launch at the FIT Show last year, we have developed Lignum™, a UK-design, PAS 24 tested window system. While some timber window systems have accreditations, they are often European in design, with ultra-modern styling and chunky outerframes, commonly used with tilt-and-turn mechanisms. Having a UK design of the window was key for us as most UK homes require slimmer frames and more traditional multi-pane openings.  
As well as having a suite of UK style window and door designs, Lignum ticks all the boxes for easy manufacturing. The founder members of the Joinery Network clubbed together to fund the development of the system, and pay for product testing, to create a complete range of timber windows and doors. 
The reason for doing this is because we shared the frustration that timber windows had become a niche product rather than a popular, natural choice for UK homes. Eight leading companies are behind The Joinery Network. The first task was to bring a consistent supply of timber windows, manufactured to all the regulations new build homes require, the same standards that PVCu and aluminium installers expect. This means we will create a network of manufacturers for installers to get hold of the products they want, when they want them. 
The Joinery Network consists of eight founder partners: BJ Waller, Balls2 Marketing, CalWin, Close Brothers, DJH Group Ltd, Fiscale, Leitz Tooling UK, and OT Dare Joinery Consultants. Together, we offer a complete range of specialisation for window fabrication. Alongside my 30 years’ experience in manufacturing timber windows, we also have tooling, hardware, finance, tax credits, joinery software and marketing. 
Lignum, by The Joinery Network, includes a comprehensive range of every product fabricators need to offer a suited range of certified windows and doors. It includes top & side swing flush casement, vertical sliding box sash windows, vertical sliding spiral balance, and storm-proof windows. For doors, there are entrance doors, (including low thresholds), French doors, single doors, (including in & out opening), and bifold doors.
We’ve invested in testing Lignum to PAS 24:2016 for security – this is the latest standard required for SBD and Document Q; and BS 6375: 1 for weathertightness and energy efficiency; as well as Document M for accessibility. This means all products in the range are tested to the most up to date Building Regulations. 
With testing now complete, we offer licences for fabricators and joinery manufacturers on individual windows and doors, so that companies can choose the products they want. They can have just one licence, the whole range – or anything between. This means that fabricators can now manufacture a certified timber window at a fraction of the cost of designing and certifying their own product. 
The Joinery Network partners have already provided expertise to support joinery companies to set up efficient timber window and door lines and are already seeing Lignum windows and doors being manufactured and installed into new build and refurbishment projects. 
The Joinery Network is committed to building a network of independent timber window and door manufacturers. There’s lots of information on the website and we run regular events. These hands-on workshops offer visitors the opportunity to see the finished products, as well as the machinery and tooling. The new Lignum branding and marketing support will also be available. There’s also an opportunity to talk with all the founder partners and affiliates. 
The next event is on 14 May and it’s hosted by one of our affiliate members Teknos, the window and door coatings specialist. Teknos is based in Launton, near Bicester in Oxfordshire.
