Hi guys,
i'm putting a floating floor on my extension concrete base.
25mm polystyrene boards with 18 or 2mm t&g chipboard on top.
Now having looked around there seems to be a few different grades of chipboad to use, P4 being a common one.
Using 2mm will give me a better chance of the floor levelling up with the kitchen.
So, can someone tell me the correct grade for the job, I will be fitting Karndean over the top. Also, how much per sheet should i expect to pay for 22mm chipboard and 25mm polystyrene boards and where can i get them from online.
Many thanks for your help.
