On a scorching summer afternoon, I noticed my aluminium window frame felt a bit loose. At first, I thought I hadn’t closed it properly, but when I pushed against it, there was a slight wobble. Last winter, it was snug and firm, so this sudden change puzzled me. Could the intense heat be affecting the metal? I ran my fingers along the edges, checking for gaps or shifts. A faint creaking sound echoed when I pressed the frame. Concerned, I wondered if this was normal or if I needed repairs before it got worse. What was causing this issue?
