Our most efficient Profiles

Our popular uPVC casement windows are multi-chambered, using double and triple glazing for enhanced thermal efficiency allowing you to rely less on central heating with expertly made, A-energy rated windows.

Making the Switch

We are committed to reducing our carbon emissions by switching to renewable and more sustainable energy sources. To achieve this, we manufacture with sustainability in mind and produce products that are energy efficient.

Beyond lowering energy usage, we’re invested in products like solar panels, which have already contributed to a 101,105kg carbon offset. Our partners share our commitment to the sustainable fabrication of windows and doors. We are united on all fronts to make the switch.

When our premium quality products reach the end of their long product life, we ensure that they can enjoy life anew through recycling post consumer waste. We support our customers by recovering uPVC, aluminium and steel materials. This way, little to no material ends up in a landfill.

We are doing our bit to lower our carbon footprint through recycling and manufacturing using sustainable materials. New generations of products like ours contribute to a circular economy. Try out our energy saving calculator to see the difference our products make.
