The design, construction, and operation of equipment to investigate the response of coloured, open, uPVC profiles to solar gain

Laminated and dark coloured uPVC profiles, when exposed to sunlightduring normal use, may occasionallysuffer deformation. To gain a greater understanding of this phenomenon, a number of test rigs were developed to recreate the temperature increase, through the use of infrared heating elements, to simulate varying intensities of solar radiation.
