Always stylish, always in demand

At our company, we take immense pride in the quality of our products, which is why we have invested in the most advanced tooling and extrusion technology available. Our commitment to excellence is reflected in the impeccable standard of our profiles, each one carefully crafted to ensure that every dimension is precise and every detail perfect. This level of quality not only enhances the reputation of our company but also ensures that our customers receive products that are trouble-free during installation and for many years to come.

One of the key features of our products is the Bubblex gaskets, which offer consistent compression and sealing that prevent air leakage and ensure that windows are energy efficient. Additionally, our deeper drainage channels are designed to clear water away from the frames and sealed units, preventing damage and prolonging the life of the window. The central Eurogroove on the sash and strategic wall thickening provide reliable hardware fixing, and the clip-in beads make glazing quick and easy without the need for security glazing clips to meet PAS24 standards. We also use recycled thermal inserts to the outer frame and sash to improve window energy ratings without resorting to the most expensive gas-filled units, thus providing our customers with cost-effective and environmentally friendly solutions.
