The coloured acrylic layer is twice as hard as the PVC surface of white windows. It is highly scratch-resistant and is largely resistant to the effects of weather. The semi-matt, smooth and non-porous surface is insensitive to accumulations of dust and dirt. There is no spalling or chipping and no need for laborious repainting.
