Profile: CR Windows offers windows, doors & conservatories, whilst providing options and designs in a variety of colors & finishes. Our windows are available with two distinctive styles of frame and beading. The chamfered option is a contemporary, straight-edged style, while ovolo sculptured beading gives a more traditional, decorative finish to window. Both options are available across our entire range of windows. All of our installers & our surveyor are certified and audited by the british standards Institute.
