When installing aluminum siding, how should you space joints around windows and doors?

When installing aluminum siding around windows and doors, it's essential to maintain a 1/4 inch space at the joints. This spacing is crucial because it allows for expansion and contraction of the aluminum siding due to temperature changes. Metal siding materials, like aluminum, can expand significantly when exposed to heat and contract in cooler temperatures. If the joints are installed too snugly or tightly, there is a risk of warping, buckling, or tearing, which can lead to damage over time. The 1/4 inch spacing provides the necessary room for this natural movement while also ensuring that there is no restriction that could negatively affect the siding's integrity. Additionally, this space aids in effective water drainage, helping to prevent moisture issues that could arise if water collects in the seams.
