What is the definition of coefficient of thermal expansion? How do building materials change in dimension in response to temperature changes, sun, shade, ice, snow? How do the dimensions of different buidling materials vary with temperature, heat, cold? Table of Coefficient of Expansion of Building Materials Questions..
Based on an expansion coefficient of 0.040 mm per 1 C per 1 m length. We recommend applying the same values for the UPM ProFi Alu Rail. Unlike conventional wpc and timber decks, UPM ProFi Deck is virtually lignin free, and will therefore not suffer from the usual greying. Instead, over the years, the colours will fade
