Do installation considerations like expansion joints for wood apply?

A: No, it is not necessary. This is one of its major advantages over real wood. ACP has a very low thermal expansion coefficient and stable properties. Its installation system is identical to regular ACP curtain walls – standard metal panel joint design suffices (typically 4-8mm gaps for drainage and thermal movement). Wide expansion joints like those for wood are not needed. This simplifies design and ensures a neat, clean facade appearance.
