Would adding some sort of window or vent in an aluminium shed be a good idea?

Question

too prevent mold or mildew from forming on stored items

Answer 1

It is really not necessary. It may reduce condensation inside the shed, but that won't hurt aluminum. It may be beneficial for what you store in the shed.

Answer 2

Most of these answers are correct, trickle vents will help but are not really the answer. My advice as a window fitter of many years is to sort out the humidity first then call a professional to fit the trickle vents, if your windows are of good quality they will almost certainly be reinforced making fitting the vents yourself very difficult. Another point a Fensa ticket is no guarantee of quality either in product or installer efficiency its basically a register for the industry, contact your local council they should be able to intervein with your contractor if they feel the work or products are unsatisfactory

Answer 3

I would defenitly help anything that was to be stored in the shed, especially if its stuff that you don't use very often.
