Cladding old school classroom

[TheSiteSupervisor]

Hello,

Very new to the site, always search here before I undertake a project that im unsure of.

A little about me first. I'm a Carpenter by trade but recently given up the building trade to more humble of possitions. I now work as a Site Supervisor at a local school.

Still the same hours etc but the work is less demanding and I enjoy the Health and Safety side of things!

Now if you would be so kind as to help me decide where to start with this!

This is our tempory (25yrs old) classroom.

Asyou may see its in a very bad state of repair.
I plan to clad this building in new treated Shiplap timber and then stain.
I would like to also insulate it some more against heat loss as you can imagne it is quite the energy sap.

Now I would like to know other peoples thoughts on the best way to start. It has electrics running though the building walls.

Currently it is 3x2 timbers, covered in a 9mm ply and then painted with the artex type stuff. I first thought to insulate with super9 rolls, batton then clad.

But i may hit electric wires running thorough! So do you think it may be worth removing all the ply and starting from bare walls?

Although it may cost a little more in skip hire etc it will be safe that nailing through and hitting the voltage!

I do welcome any ideas or thoughts and really od look forward to hearing them!

Kind Regards

Jack!

You first need to clarify whether this structure has to meet Building Regulations if it is modified.

For thermal insulation I would clad on the inside with a vinyl faced plasterboard. For weather protection on the outside use a plastisol coated steel sheet.

There are cabin companies that specialise in such refurbishments.

The studs will be spaced at a repeating distance, therefore identify one on the external panel and the rest can be measured with accuracy.
At the first stud hammer a nail (pressed hard to the stud side) through from the interior to the exterior, one each side of the stud, high up and one each side low down. mark with chalk the resulting center of the stud both top and bottom, and ping a chalk line to highlight it. You can now trust to tape measurement, either from a stick pined to the chalk line or use of a rod marked off from the internal studs placed and held against the chalk line.

What you have at present is effectively a timber fame building and if you work from that point of view the present cladding can be classed as a vapor barrier.
Trada offer a series of technical bulletins re timber cladding to timber frames, why not put in a search...pinenot
