As a non-glazier I would presume that standard white uPVC frames have the cheapest cost, whereas the same frames in another colour would be more expensive.
If only the outside section of the uPVC frames have a colour and the inside section of the frames remain white (if this is possible), is this cheaper than having both the external and also the internal portions of the uPVC frames in a non-white colour?
What sort of percentages added to all-white frames might we be talking for non-white on external only or alternatively non-white on both external/internal sides?
Generally speaking, are non-white colours selected from the RAL chart?
Thanks.
