Fresh, white UPVC bay window and Chartwell Green Palladio door that lift the property and complement the traditional features. The design now allows more light in than the previous window and retains heat through its clever energy saving properties. The glass allows natural sunlight to heat the room but does not allow it to pass back through thanks to the Planitherm coating. The argon filled cavity and 5 chambered UPVC profile also help to keep valuable heat in and ultimately reduce energy bills. The windows and the door achieve the best of both worlds, keeping a traditional appearance but are energy efficient, secure and functional.
