I am very pleased with my installation! It has turned my conservatory, which was hot in the summer and freezing cold into a room I can use all year round. Combined with underfloor heating it is now the most pleasant room in the house. The installers were clean, polite and worked hard all day. I had looked at other systems ( strips in the polycarbon roof) but quite frankly, they are a waste of money. I am very happy to recommend Sun-Room to anyone who seeks these benefits.
