Very good advice, very good installation. The windows and doors are of a good quality. We had a very warm summer and, although half a side of the house is glazed to the south, it was pleasantly cool in the house, so little heat loss. Furthermore, as the builder, I was made aware of things that I did not have in mind. The order for the doors was placed in May, the final completion in October, which is due to the current situation (Corona, Russian war).
