Garage Conversion into Storeroom and Office - Advice Needed

Postby TheMightyAtom » Mon Jan 05, 2015 6:22 am

I would like to convert our garage into a storeroom/office.

I am new to DIY and from reading on the web I understand the first thing to do is insulate and then cover with a chipboard floor.

I hope someone can advice on the following:

[list=]How far apart and what thickness should I make the floor joists?
What would should I make the joists from?
What is the correct insulation to use?
Do I need a damp proof membrane on both sides (the side nearest the concrete slab and the side nearest the room)? [/list]

Thanks in advance for your help.

Hi TheMightyAtom,
A good place to start with this question is here:

Regarding your flooring and the joists, there is a lot of information available here: ... ooring.htm

Regarding your other questions, it will depend on what is already there. Find out more about damp proofing a garage floor here: ... pfloor.htm

And for more general information on garages have a look at the section here: ... ilding.htm

Hopefully that will give you a good start - good luck with the project!
