Afternoon,
Looking for some expert advice as I am a DIY beginner hoping to build a garden workshop. The concrete slab is existing and has a dpm.
Floor construction on top of concrete slab is proposed as follows:-
50x50mm timber battens.
50mm Celotex GA4000 insulation between battens.
22mm chipboard.
My question is do I need some type of vapour control layer for the installation?
Also if so what type of vcl is recommended and where should it be located?
Any advice on the above is very much appreciated.
Many thanks in advance to any comments.
