Garden Shed Utility / Office slabbing query?

gelli86

I have recently got a steel shed 40mm insulated shed installed in my garden. I plan to use it as a utility and office.

I am planning on insulting the walls with some YBS insulated foil rolls and some 50mm quinntherm rigid insulation on the roof.

Ideally I would like to install rock wool on all the walls however it seems expensive for what I will be using it for. Any cost effect suggestions please shout...

Also my main query is what would people suggest slabbing the walls with. I am happy to go with plywood instead of plasterboard. I was thinking 12mm birch ply, but I'm wondering would 12 or 9mm hardwood faced ply be suitable for slabbing the walls and pitched roof?

Cheers

Either ply is fine.

You must consider ventilation. If your in there for hours of the day you will create moisture . That has to escape some way.

Good point.

The shed has two windows with vents, but something to be aware of.

I'll go with the cheaper of the two timbers and use csk self driving tapping screws. The screws will need to be thin enough to bight the thin shed frame. I'm looking at options now.

Rather than using self tappers to screw each sheet to the cladding rails why not batten out the shed and just use regular chipboard pozis to fix through to the battens. It should help the sheets to go up quicker and you'll get an opportunity to straighten out any areas that are not plumb or square.

Fun facts...

1. Birch is hardwood.
2. The strongest bit of plywood is the face veneers, so thinner ply is relatively stronger for its thickness

I'm currently working with 9mm birch ply. It's pretty strong.
