PVC-U is one of the most widely used plastics materials for building components. This Digest describes the weathering qualities of self-coloured PVC-U used externally. White is by far the most common colour for most applications, having the advantage over dark colours of remaining much cooler in strong sunshine.
The principal cause of degradation of PVC-U used externally on buildings is the action of UV light, which is present in direct sunlight and, at lesser intensities, in daylight scattered from the sky and clouds. The effect of weathering on appearance and on the mechanical properties is discussed. The Digest then describes artificial weathering tests and relevant standards for PVC-U products.
