I had to chase the delivery date, then told if I had not called I would have received a text that night for the next day's delivery! Too short notice for people who work. Delivery not complete, missing item. Also, the boards have to be stored flat 2.4x1.0mtr stored flat, very difficult to store. Fitted this weekend. All went well until a piece of panel dropped from 20cm onto the sealing strip and cracked it. Seems very brittle. The panels look good but I need to know to cover the sealing strip with another sealing strip. Would buy again, as the price is very competitive.
