Hi, I live in a house from the 70s.
It has brick, 16mm glespanel, 12mm asfaboard, 80mm insulation, 16mm panel and 12mm wood fiberboard (tretex?) on it.
I am renovating and thinking of replacing the tretex with 13mm gypsum board (for smoother walls).
The question is if it's a bad idea? Do you lose a lot of insulation? I've read it should be equivalent to 45mm wood, but now the walls are already insulated with 80mm insulation, so does the tretex really make a difference?
Are wood fiberboard and tretex the same thing?
What have you done?

Treetex was a brand for a soft wood fiberboard. Wood fiberboards have an insulation value that is slightly worse than mineral wool. I would estimate the insulation value of your wall, 12 mm asfaboard + 80 mm insulation + 12 treetex as equivalent to 100 mm mineral wool. This is normal 50-60 false standard, but not much compared to today's levels of about 250 - 300 mm. If you don't intend to do any major additional insulation, it's best to keep the treetex and place the plasterboard on top of it.
Okay no, I don't plan to add extra insulation. It will be a bit tricky to get around the windows. What's better, regular or renovation plasterboard, there's a 7mm difference but I guess it'll need fixing around the windows anyway...
13 mm costs about half as much, easier to screw in, and there are ready-made 13 mm trims available to fit around windows with.
Anyone have tips on the best way to do it behind the radiator?
They are waterborne, probably can fit 13mm gypsum between the wall and the radiator/pipes, but it might be difficult to install the baseboard afterwards.
It's a wooden joist, the floor is going to be replaced, so the question is whether the radiator can be moved out 13mm (how rigid are the pipes if you lift the floor)?
