By default your door is supplied with a full PVCu frame. If you select the low threshold option then the bottom section of the door will be substituted for the Clearview 15mm low threshold.

Both threshold options will sit on top of either the 85mm or 150mm sills. The door will be manufactured to the sizes given previously whilst incorporating whichever sill and threshold combination is selected.

For example if the height entered was 2100mm and a PVCu sill is selected (which is 30mm high) then the door will be manufactured to 2070mm high so that 2100mm is achieved with the sill.

If no sill or low threshold is chosen then you have the option to select your drainage position. In the absence of a sill or low threshold or indicated otherwise we will default to face drainage.
