For window and door fabricators, balancing the demands of verifying regulatory compliance, energy efficiency, and customer expectations is no small feat.
As part of Quanex, the team at Liniar understand those pressures first-hand and have been working hard to automate and refresh their existing calculator with a brand-new Energy Performance Calculator.
On Tuesday 22nd and Wednesday 23rd of July Liniar customers are invited to an exclusive demo and Q&A session as part of our online launch event.
Speed Meets Accuracy

Daryl Fradley
Daryl Fradley, Liniar’s Design & Fabrication Director, led the complete overhaul of Liniar’s Energy Performance Calculator, which was one of the UK’s first online energy efficiency tools. This latest project has seen Liniar’s in-house Design and IT teams collaborating to deliver a fully bespoke piece of software.
“We’ve designed the all-new Energy Performance Calculator for accuracy, speed, and total transparency,” he explains. This next-generation tool is accessible to Liniar customers through Liniar Connect and delivers real-time U-values and BFRC-approved energy performance reports in under a minute, giving users in-depth insights with just a few clicks.”
He continues, “We’re excited to host our online event and demonstrate this fantastic tool to our customers – it’s genuinely going to make their lives so much easier.
“Whether you’re preparing quotes, supporting building control documentation, or educating homeowners, the calculator removes any guesswork and standardises reporting – all with dynamic data that adjusts automatically as you input different glazing, spacer bars, or frame configurations and much more.
“That flexibility isn’t just a nice-to-have. In a marketplace where every decimal in thermal performance can impact customer decisions, reliable simulations are vital. The tool lets users build and save a library of configurations, making it easy to reference or repeat simulations with consistency. Each report includes a breakdown of thermal performance, a frame summary, detailed cross-sectional drawings, and in-depth sim values – so it’s not just data, it’s valuable insight.
Selling with Confidence
As the fenestration industry evolves, it’s crucial that the tools to support it keep pace, something the team at Liniar have recognised and invested in providing.
Daryl concludes, “We firmly believe when it comes to energy performance, accuracy and transparency are more than regulatory checkboxes, they’re a key differentiator – you’re not just selling a product, you’re selling confidence along the entire supply chain.
Invites to the EPC launch webinar will be landing in inboxes soon – if you’re a Liniar customer, keep an eye out and save the date! For more information on Liniar’s full product range, visit www.liniar.co.uk
