At UTFL, we are proud to introduce : a cutting-edge fabrication method that sets a new benchmark for the Residence Collection of PVC-U windows and doors. By combining traditional aesthetics with state-of-the-art precision CNC milling, we achieve levels of accuracy, consistency and finish that set HeritageWeld® apart in this type of joint.
A New Standard in timber-effect fabrication
The demand for traditional, handcrafted aesthetics in modern materials continues to grow. Historically, replicating that look has involved compromises — most notably glass-bonded sashes.
HeritageWeld® was developed to move beyond those constraints, delivering a with enhanced durability and precision — and crucially removing the need for glass bonding, saving time and money on every installation.
Our helps ensure the joint is produced with a high level of repeatability, retaining the authentic charm associated with classic timber windows while maximising the benefits of modern engineering.
Unrivalled Precision & Authentic joint detailing
Unlike earlier approaches — including conventional welding, or the use of a mechanical corner cleat combined with glass bonding — HeritageWeld® incorporates high-precision CNC milling to refine and enhance every joint.
This ensures:
Innovation backed by investment
Mechanical fabrication methods were a step forward for the industry — and HeritageWeld® builds on that progress. By investing in the latest , we have elevated control and precision so that every HeritageWeld® joint meets uncompromising standards.
The outcome is a joint that is not only visually superior, but also stronger and more durable than previous methods allowed.
Confidence you can specify
Quality isn’t just something we talk about — we back it. That’s why we introduced our market-first If It’s Faulty It’s Free guarantee.
If we manufacture and deliver a product that cannot be installed due to a proven manufacturing fault, we’ll replace it and issue a credit for the full value of the faulty item against your next order (subject to the full terms, conditions and exclusions).
Industry recognition
UTFL was named a 2025 , reflecting our focus on customer-led innovation and consistently high standards across our portfolio.
