When describing the shapes of the UPVC window profile extrusions that we stock and work with, we use the following terms that are different depending on the window profile extruder but all mean the same thing.

• Flat, Chamfered, Bevelled are all ways to describe a profile with simple flat angled edges to it
• Sculptured, Ogee, Contoured, Featured, Ovolo are all ways of describing a profile the has curved decorative edges to it
