I have a 4.5mtr wide by 3.5mtr deep edwardian dwarf wall conservatory with polycarbonate roof and am looking to replace the roof so we can use it in the winter, its on a north wall so summer overheating is not a problem its just right.
Question is whats the rough price for replacing the roof with clear Argon filled glass or an insulated roof tile version and any suggestions and advice please?
