Great product and service. Whenever I rang for advice, or with questions from the builder they were immediately answered on the phone. The doors arrived promptly with fantastic delivery men who helped get them inside and helped us inspect the packaging. We had no issues with the doors, very well packaged. The builders were able to assemble them extremely easily and quickly, we had no issues at all with the construction and installation. As you can see from the pictures, the extension is still a work in progress so you can't see them in all their glory, but they are beautiful, well priced for the quality and we're delighted to find them triple glaze with a U value of 1.0.
