Hi all, looking for some advice on how best to insulate our main bedroom and ensuite which essentially sit within in the roof space.
These rooms have always been much colder than the rest of the house and while re-doing the ensuite it seemed like a good opportunity to punch a hole in the wall to the cavity behind to see what the situation was.
There was no insulation behind the ensuite, plasterboard straight out to the roof space, behind the bedroom on the vertical walls and 45 degree ceilings there was a thin foil blanket that doesn't seem to be doing much.
There was no insulation on the floor which is essentially the ceiling of the room below.
My thoughts were to lay 100mm of rockwool on all the floors and walls, and use 50mm on the 45 degree slopes where ventilation needs to be maintained on the underside of the rafters, does this seem like a good idea
I'm not even sure if it will be physically possible to get to the 45 degree slopes to fit insulation.
Void behind shower, with no insulation, the floor is the ceiling of the room below - this would be the most accessible space.
Most of the void is this size with a thin foil backed blanket, I could just about crawl down here, at the top of the wall on the left it transitions to a 45 degree slope celling.
