As a company service was excellent , I got good friendly help on the phone, and a good delivery service . A great company to buy from and deal with . The door I ordered is the cheapest and it shows , the horizontal panels are open at the sides they light and rain in at the edges water pools ot base of door in bad weather Fitting instructions were poor , if your a diy person you would struggle in use the Novatherm Merlin canopy door is sprung heavily at closing point to allow enough tension to open properly , with a poor latch system operation , the door doesn’t open fully horizontal , it has stops in the runners about 100mm before it’s fully open and level , worst of all the horizontal panels have huge gaps where they meet the frame sides , it lets light and draught in and in windy weather the rain is also forced in , see photo I wouldn’t recomend this door at all My 30 plus year old Garador mk3 in my another garage is much better .
