1/ Check to see what is used for the windows. Is it glass, which does not rattle, or styrene or perspex? If it is perspex or styrene then this is susceptible to scratches and will lose its clarity within a few short years. Is it toughened glass for safety?
2/ Glass is normally at least 3mm thick. On many of the cheap sheds available they use perspex or styrene, which normally is ½ (1.5m) the thickness of glass. This means that as it is so thin it moves when the wind blows it. It can also be noisy. It is used is because it is cheaper than glass
3/ Do any windows open as standard, or if there an option to have an opening window, which would allow air to circulate in your garden shed. Do the windows have window ledges and are they sealed properly?
All our garden sheds, with the exception of children's playhouses, have proper glass windows which are 3mm thick (minimum). These remains clear and do not rattle when the wind blows. On the Diamond and Platinum garden buildings they have toughened glass as standard - no extra charge - how good is that? We can also offer Toughened, Laminated or Wired glass if you would like safety glass. Most of our buildings have opening windows as standard, or as an option. Also, on most of our garden buildings direct from us, they have proper window ledges and sealed.
