Insulating a solid Block shed

Captainaxiom

Im looking for recommendations on insulating a 6” single leaf block shed. It’ll be used to store tools, lawnmower and over flow from the house. Shed is built, no insulation under the slab. Non insulated roller door is already installed and metal side door. No ceiling or roof insulation.
Is there a point to insulating it at all. Bare block on the inside.

It’s been suggested to use 50mm or 70mm xtraterm with 9mm ply

I dont see the point. You will gain nothing.

I agree with mickdw, with an uninsulated roller door, and nothing under the slab, anything gained by insulating the walls and ceiling will be minimal at best.

Why do you want to insulate it if its only for storage?

Would plastering the inside bare block walls be any benefit. Don’t want tools rusting or electric tools getting damaged. No major issue at the min with water or damp. Outside is plastered. Slight bit of water at door and roller but I’ve to install eco-drain along that side when the yard is getting concreted.

Ordinary electric stuff such as drills etc would be fine unless left for years untouched.
If you were going to have computers out there, you would want it heated and insulated.

Ordinary hand tools would rust over time if left in a shed.

Wanted to see if there’s a benefit before I fill it full of crap, realise my mistake and have to empty it out to do it.

I’ve a couple of cans of floor paint left over could paint the walls or would I be better off leaving the bare blocks alone in case driving rain made its way through the plaster coat so it could dry out. ??

Your biggest issue with a single solid wall shed is water coming through.
Out west where we are, everyone with sense builds a double wall shed to ensure its dry.
Id leave as is or do a steel float sand cement finish internally.

The outside was sealed with SBR, heavy scratch, & steel floated no issue so far with water coming in. So is there a point to even plastering the inside.

Thanks for the replies so far.

Based on the above I’d leave it the way it is.

No point insulating the walls of a shoe box if you leave the lid off.

Plan was to do the walls now, roof could be done after even with the shed full. Yeah

You could say its badly built, call it a barna shed??

But honestly,
I would see no point insulating a shed, unless it was done all right, and a complete thorough job.
If you arent heating it, why insulate it, whether you look at it from the point of view of

A. Heat loss,
you arent heating it, therefore insulation doesnt save on or limit heat loss.
Result: No point insulating


B. Cost or cost saving
You arent heating so there is no saving on cost by limiting heat loss, so you cannot recover the cost of insulation from savings in heat,
Result: No point insulating


Even insulating poorly/incorrectly is just a waste of money,
imagine insulation like a bicycle tube, if there is a hole the air leaves there.
likewise insulation, if there is a hole or weak point the heat just goes out there, unless you were storing something very valuable and you intended on heating the structure, like vintage vehicles, in that case Id suggest airtightness/insulation, and it would help reduce the costs of heating and limit the effects of moisture.

Thanks for the replies my mind is made up and my bank balance is healthier for it.
