I have recently replaced my Kitchen.
I removed all the plaster to the walls and ceiling. There was a couple of leaks on under the flat roof (felted and stone chipped). I had these repaired. ( weeping only ).
I then installed Xtratherm between the joists to the flat roof 140mm joists are about 200mm deep and then plastered under joists. Leaving about a 50mm gap between top of insulation and bottom of chipboard.
The flat roof seems to have been an unvented roof now I think of it.
Will this be ok, or am I likely to get condensation problems on the timber under the felt?
If this is a problem, is their a way to fix it without ripping the ceiling down, as I would not be popular!
There were no problems before I installed the insulation and it was still a closed construction, and I have re-ducted the stove fan to the outside wall, so there should not be a lot of steam in the kitchen. Dryer now in garage.
Any help...... would be appreciated.
