Honey comb double cell, 3 blinds, 2 at about 850 wide and one 2.4M wide 2.4 M drop, Went on line, worked my way through the process (hint, screen copy your final order) then submit the order, they check back with you so double check you have everything right, fast turnaround, easy to install, ( hint make them 25 mm longer)
Very helpfull, I would use them again, bought the double cell, keeps the heat in and the cold out.
