So you're saying that you use 25mm ply instead of overboarding as the customer won't accept the 5mm increase in height ?
I thought I had Fussy customers
I don't think you even give them the option, like myself you just do it.
I don't purely overboard, I replace onto joists probably on 80% of the jobs.
I'm simply voicing my opinion that overboarding is totally acceptible and give's an increase in height of just 5mm against using 25mm ply and 12mm increase against using 18mm ply onto joists.
Most underlays and carpets are a good 20mm at least, as mentioned, Oak threashiold as your trasition....... perfectly Fine and by no means amatuerish.
Edit: just to add, I'm not nit picking, we're having a light hearted discussion with a bit of friendly banter chucked it, I for one enjoy it, I reckon you would too if you joined in.......now.....I expect a couple of rolling eye smileys and a wink at the end the next time we clash on anothe threadif you're up for a bit of banter
Oh yeah, the last five or so jobs I have done I have gutted the room, replaced boards with green grade chipboard then glued and screwed Aquapanel onto it, a few were wet rooms, a couple were stone floors. You can't beat tiling onto a backer board. I know a lot of people that do what you do (18mm ply onto bare joist) then use the 6mm Hardibacker, and are OK.
