Garage convertion help - assume I know nothing!

[bobbyb]

Hi everyone, 

 

Im in the process of converting one-half of a single-skin double garage into an office and workshop. It's all pretty simple (in principle) but where I seem to be perpetually confused is the best way to tackle the insulation install. There seems to be so much info out there and so many ways to do it I'm a little lost in what is the best approach.

 

My plan currently is as follows

Build stud wall (easy)  

Install stud wall with an air gap behind (gap depths? No idea at the moment)

Insert 1st layer of insulation board between batons

Overlay 2nd insulation board over the previous insulation and batons resulting in one uninterrupted layer of insulation

cover all gaps with aluminum tape to create a vapor barrier. 

Finish with plasterboard or OSB/MDF

 

One thing I have noticed is the garage does have a few weep vents (or in my case just little holes in between the bricks)

after the 4 walls are one, Ill be moving onto the floor and ceiling. 

so with that, can anyone tell me of this is or is not a good approach, or whatever? cheers!

It looks OK.  25mm gap will work.

Yes a good start, rather than installing the insulation after building the stud work I was on a build once where the insulation was installed against the first stud then the second stud was installed  tight against the insulation etc etc. what do you plan for the floor, roof and doorway?
