Bit of a strange question but I'm trying to figure out the thickness of carpet & underlay. I'm allowing 10mm for underlay but a bit stumped when it comes to the carpet.
The reason I'm asking is that I have a hallway that has 3 rooms off it that will be carpeted (with what I have no idea at this stage) but the hall will be polished floorboards over ply, I know that thickness of the floorboards (19mm more or less) but now I'm trying to work out what thickness of ply I will need.
I know it depends on carpet type etc - I don't really know yet, suffice to say it won't be shagpile! - just trying to get an idea on thickness.
