Top Service, Friendly Staff I can highly recommend Cor-Line Systems, Harrison is great to deal with and makes things happen in a timely and professional manner. We are a high end builder specialising in oak framed buildings and source all of our bifolds from Cor-Line, the technical department were happy to work with us to develop a way of installation that gives the forgiveness needed when fitting in to oak frames.

We ordered 3 sets of Cor-Line windows, Graham was very helpful, quick to turn round quotes and the windows actually arrived earlier than expected. Stunning product and happily recommend
