Replacement Conservatory with new Glass Roof: Would have been perfect but for one wedge 3 pane glass piece coming from factory at wrong size. Temporary filler made but took 4 weeks for replacement correct size to be obtained from factory plus 2 pieces of trim were overlooked but corrected as soon as requested. Otherwise a first class job at best price obtained from 3 possible suppliers. This supplier was only one who explained the limitations of loads area in the new roof with self cleaning glass roof rather than previous plastic type. This enabled improved option to be chosen on configuration of roof against competitors intention with muntin bars.
