Liniar's Barrier & Wind Load Calculator

As regulatory scrutiny increases and project timelines tighten, window and door fabricators are under more pressure than ever to demonstrate compliance while maintaining efficiency. Structural performance, barrier and wind load calculations are complex, but fundamental to safe, compliant manufacture. Yet for many businesses, accessing accurate data quickly remains a challenge.

Making Calculations Accessible

Following the recent release of its Energy Performance Calculator, Quanex brand Liniar continues to invest in developing tools that help customers simplify complex processes. Its upcoming Barrier and Wind Load Calculator will greatly simplify Building Regulations Part K and BS 6180 compliance – and crucially it has been underwritten by a structural engineer.

As Liniar Design Manager, Tom MacKenzie-Roberts explains, “We’re committed to raising awareness of how important it is to make barrier and wind load calculations before manufacturing. Getting this right upfront ensures regulatory compliance, avoids potential for costly remedial work and even legal ramifications in event of structural failure. Safe buildings mean peace-of-mind across the board.”

User-friendly, Practical Accuracy

Designed with user-friendliness in mind, “The calculator’s interface is very intuitive, while delivering impressive functionality” says Tom. “Fabricators can calculate stiffness and deflection values for a member being assessed in a window or door. It includes integrated peak velocity pressure by post code, for greater performance accuracy in any location across the UK,” he adds.

For fabricators, this means faster decision-making and greater confidence in specifications. Being able to make calculations quickly and accurately also has the benefit of reducing the time it takes to prepare quotations, ultimately shortening lead times - a great competitive advantage!

Compliance Starts with the Right Components

Of course, calculations are only part of the picture. There’s a wide variety of components available on the market of varying quality - choosing only those that have been fully tested and certified is crucial to achieving finished products that deliver on performance reliably. 

Tom continues, “At Liniar we adhere to stringent testing processes in developing regulatory compliant products. Our PVCu Thermal Reinforcements range, for example, has been tested in vital areas such as screw retention, barrier loading and security.

“By following strict testing practices for all our products, both in-house and through independent 3rd parties, we have complete confidence when advising our customers on which components will deliver to the required specifications under a wide range of conditions.”

Supporting Safer Construction

Liniar’s Barrier and Wind Load calculator will be available to its customers free and will be supported by training during the initial roll-out phase scheduled to commence at the beginning of March. Tom concludes, “By giving fabricators the tools they need to work accurately, compliantly and efficiently, we’re supporting safer construction and stronger businesses.”
