Steel shed ventilation
 

We have a sheet steel garden shed, and with any sun at all it gets
unbearably hot inside.

We put up polystryene slabs under the roof, but that was to stop the
condensation dripping down inside in the winter. It does not help with the
problem of the shed getting too hot.

Grateful for any suggestions as to best how to keep it cooler in this warm
weather, please.

Trying to cut out holes in that tin sheeting would I guess be a difficult
task, and I've no idea if it would be of much help? Thanks for any advice.

There is a limit to what you can do in a small space without any
airflow. Paradoxically your best bet might be to glue aluminium foil
onto the underside of the polystyrene slab. This slows down ingress of
solar heat by making it harder for the polystyrene to radiate energy.

The other trick is to make the exterior partially or entirely self
shading by having a second outer skin on battens. Ivy works pretty well
as it includes its own airconditioning and looks better than sheet steel.

Letting the hottest air out the top and allowing cooler air in at ground
level will help a bit. You want a vent that lets hot air out but doesn't
allow rain to get in.

Painting it white could be a good move, as could putting a secondary
roof above the first with an air gap between them. Also, maybe a small
solar powered fan in a window or door might help.

All of these work quite well on Land Rovers.

Solar panel & 12V computer fan. A bit of battery helps (and a diode in
series with the solar panel), but you don't need smarts

If you're working in or around it, leave the door open.
If you're not in the shed , does it matter how hot it is inside?

It doesn't do paints or garden pesticides much good to be excessively
hot or in strong sunlight. Oxidation and loss of solvent can occur.

Maybe this sort of thing, couple near the roof line, a couple near the
floor .. ebay number 310329876456

Or a length of 130534194440 under the eaves etc

or a shed-load of drilled holes .. ;)

Can you build a little cupola in the roof and add an attic fan?

What about the obvious - a turbine / roof ventilator? The hot air is
enough to keep them moving when the wind is calm. It should be possible to
seal it off from inside the shack during the winter to trap any heat
indoors.

Good Luck.
