I have Anglain Windows providing my Doors. The doors are supposed to be fully Disability Act complaint and the threshold should be minimal. Anglain say that their product (the Threshold Cill) will only sit on a stone cill. I have to source these urgently, preferabbly locally. Can anyone advise if "standard" stone cills are available (preferably local to Leicester)? And where I can get details of these. Any guidance please. I do have drawings/specification of these thresholds if required.
