Most buyers reach for the 3m length first and order enough to cover the run, which is the right call on a long, uninterrupted parapet. But on a short return wall, a box dormer front face, a small outbuilding parapet, or the final infill section of a longer run that does not divide neatly into 3m, the 1m length is the practical choice. Ordering a 3m length for a 1.2m wall run and cutting 1.8m of waste is not economical and it does not produce a better result.

Rain soaks in, frost cycles open up mortar joints, and water works its way down through the wall construction. Coping caps the top of the wall and directs water clear of the wall face and the flat roof waterproofing layer below. Sloping coping does this with a built-in slope across the top surface, tilting toward the external face so rainwater runs off the front of the wall rather than sitting on the coping or draining back toward the roof membrane. On a domestic rear extension, a box dormer, a boundary wall, or any parapet where positive surface drainage is preferred, sloping coping is the right choice.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe 2mm gauge with a 100mm external leg is the standard domestic specification for sloping coping.

On a parapet that measures 7.4m, for example, ordering two 3m lengths and one 1m length with a short cut gives you three joints and minimal waste. Ordering three 3m lengths and cutting 1.6m of waste from the last section costs more in material and produces no installation advantage.

This must match the overall width of your parapet wall construction. For a 2mm sloping coping with a 100mm external leg and 75mm internal leg with standard 10mm returns, the formula is: wall width + 195mm = the size to order.
