Market-leading PVCu systems house Liniar is once again paving the way for sustainable construction with the latest addition to its pioneering PVCu Thermal Reinforcements range.

Design and Fabrication Director, Daryl Fradley (Daz), explains, “The decision to enhance the range follows impressive market uptake since its initial rollout and underscores Liniar’s ongoing commitment to delivering high-performance, future-ready solutions for fabricators, installers and specifiers alike.” 

A sustainable steel alternative

Designed as a sustainable and cost-effective alternative to traditional steel reinforcements, Liniar’s advanced PVCu Thermal Reinforcements are playing a key role in supporting the shift towards more environmentally responsible construction methods.

Daz continues, “We developed the range with performance, sustainability and practicality in mind. Our PVCu Thermal Reinforcements are manufactured using recycled materials and are themselves fully recyclable at the end of their lifespan. The system can be used to reinforce both window and door frames - including transoms – and achieves the same reinforcement requirements as steel.”

From the range’s inception, the real challenge lay in replicating the strength and resilience of steel using a polymer-based product. That goal has been emphatically achieved - the PVCu reinforcements have undergone rigorous third-party testing by UKAS-accredited bodies and have been certified to BSI standards BS 6375 parts 1, 2 and 3, as well as PAS 24. The result is a product that matches steel for performance in critical areas such as structural integrity, screw retention and security while offering a host of additional benefits.

Enhanced thermal performance and efficiencies

“It’s not just about matching steel it’s about improving on it. Liniar’s PVCu solution offers enhanced thermal performance, delivering tangible energy-efficiency gains in final installations. Fabricators also benefit from considerable cost savings and a cleaner, more streamlined manufacturing process. Unlike steel, the PVCu reinforcements don’t require specialist cutting equipment and result in less wear and tear on consumables,” explains Daz.

“Manufacturing operatives will also appreciate the ease of handling, without sharp or burred edges, the risk of injury during fabrication is greatly reduced. While installers will find the finished frames much easier to drill as PVCu requires less force than steel.”

Investing in future development

Liniar’s continued investment in its reinforcement range reflects the brand’s broader strategy to provide efficient, and sustainable solutions that don’t compromise on quality, performance or regulatory compliance. 

With a proven track record of in-the-field performance over the past two years, and growing demand across the sector, Liniar’s PVCu Thermal reinforcements range is set to further bolster the company’s position at the forefront of the PVCu systems market.
