Cellular PVC - weathering performance -Fascias, Soffits and Cladding

All white Swish cellular PVC extrusions are manufactured using a unique formulation, designed to provide top quality weathering performance and avoid discolouration problems. Research continues into the discolouration phenomenon known as “pinking”. Two schools of thought seem to exist, with significantly different views as to the cause of the problem. Two performance tests have been proposed - The Sun test and the ACT test. Swish has tested its own material, along with multiple samples of competitors products purchased from UK stockists.
