What is TimberWeld® ?

Timberweld® technology, a patented method of jointing that achieves an unparalleled butt-joint effect on both the exterior and interior of windows. This exclusive flush sash welded system delivers an authentic traditional timber appearance and superior technical performance


Timberweld® technology represents a significant advancement in the joining of uPVC corners, creating an authentic timber butt joint effect that is visible from both inside and outside. Traditional wood foiled, butt-jointed windows have long been sought after for their aesthetic appeal. However, the conventional designs often falter, leaving windows susceptible to rainwater penetration, draughts, and infestations. Timberweld’s patented technology ensures the preservation of traditional wooden charm, free from these inherent vulnerabilities

The Aesthetic and Practical Advantages of Timberweld®

Achieving the classic look of traditional timber windows, Timberweld® excels in both aesthetic and practical terms. This patented jointing method offers more than just visual appeal—it delivers perfectly sealed butt-joints, enhancing the overall window structure

"Timberweld® enables us to meet the aesthetic expectations of homeowners who cherish the timeless elegance of wood, while enjoying the benefits of modern materials. Our dedication to innovation places us at the forefront of window fabrication, offering unparalleled quality and versatility"

Timberweld® seamlessly addresses the challenge of blending traditional aesthetics with modern performance. Windows crafted using this technology feature fully sealed edges, echoing the design of classic wooden frames, yet boasting superior durability and ease of maintenance. The outcome is a product that not only enriches the visual appeal of homes but also contributes to enhanced energy efficiency and security
