The replacement of our existing windows with the Astellite uPVC double glazed windows have transformed our house both aesthetically and environmentally. The German engineering and locking systems are first class. They keep out noise, heat and the cold and look fantastic. In addition the costs were reasonable and the customer service in particular from Damian has been absolutely outstanding and any issue has been responded with quickly and efficiently. All in all a very positive experience.
