    1.3 THERMAL EXPANSION Marley uPVC systems expand and contract at a linear thermal expansion coefficient of 0.7mm /m /10ºC. Marley spouting systems allow for the thermal expansion of uPVC using expansion outlets and Expansion joiner (MT17) expansion joiners, creating relief points Expansion outlet (MT8.80)
