When installing vinyl siding, what factor must be accounted for to allow for proper installation?

When installing vinyl siding, temperature is a crucial factor to consider because vinyl expands and contracts with changes in temperature. If the siding is installed during extreme heat or cold without accounting for this expansion and contraction, it can lead to issues such as warping, buckling, or gaps appearing in the siding. Proper installation guidelines recommend leaving space for the siding to move as temperatures fluctuate; this is often particularly emphasized in environments with a range of seasonal temperatures. Ensuring that the siding is installed in accordance with temperature recommendations helps to maintain its durability and visual appeal over time.
