Coloured UPVC windows typically carry a 20% to 30% premium over white UPVC windows, so you could end up spending big on coloured windows.
You may also notice a price disparity between UPVC brands. This is because some coloured UPVC windows have 100% colour permeation, while others only have surface colour. Most of the time, solid colours cost more.
In any case, coloured UPVC costs more than white because the manufacturing process is more complex. Depending on the brand of UPVC windows, coloured UPVC windows are made in one of two ways:
Pigmentation: this creates a solid colour with 100% permeation. Pigments are added to the plastic mix during the manufacturing process. A lot of development and experimentation goes into this process. It isn’t just a case of throwing pigments into a mix and hoping for the best. UPVC manufacturers produce plastic in big quantities, so they have to get the product perfect.
Coloured foil: this creates surface colour and/ or texture. Foils are baked onto the UPVC surface at the factory under intense light or in an oven. The foil melts into the plastic and forms a permanent bond with the plastic. Although this finish is only a surface colour, it is designed to last. The UPVC is still white underneath but the foil is unlikely to scratch off due to the strong bond.
Changing the colour of UPVC windows WITHOUT replacement
If you want coloured windows but you can’t justify the extra cost, you can get your existing windows spray painted professionally instead.
We have specialised in spray painting UPVC for over a decade. The finish lasts and we stamp our work with a 10-year guarantee.
Importantly, the finish is extremely convincing. Once we have sprayed your windows, it will be impossible to tell they have been painted at all. They will appear to have been installed in the new colour. Check out our gallery and see for yourself.
