Glazing
As well as upgrading your windows, you’ll also need to think about the type of glazing for them. Our uPVC and aluminium windows come with EcoMAX Glass™, one of the most sustainable and eco-friendly glass units on the market, as standard. You can also choose Comfort Glass for higher levels of thermal efficiency, security and noise reduction, or decorative glazing, such as stained glass, floral patterned, or modern etched glass.
Frame Options
We have a number of distinctive styles of frame to choose from. The chamfered option is a contemporary, straight-edged style while the ovolo option provides a more traditional, decorative finish. Our flush option sees sashes that finish flush with the external face of the window.
