ok guys
Got a query here!
My sister has recently bought a largte terraced house and it has a basement under the first floor. This did have a damp problem however she called a specialist in who did a new DPC and stripped all the manky white lath and plaster off the cellar ceiling, exposing the joists of the rooms above and in turn helping the ventilation.
The damp problem is now resolved however as its wooden floors above I am looking into insulating between the joists with kingspan or a similar product.
Can anyone give me advice on the best way to do it? as there seems to be a minefield of info out there!
eg/
I know an air gap needs to be left above the insulationunder the floorboards, but do I also need to leave a gap at the end of each joist run so air can flow up there? or is that going to creat a cold bridge?
I have seen it before where the whole lot has been covered in shiny reflective sheeting?
Whats the best way to fix the kingpsan between the joists? am I best to use small wooden battens or??
thanks for all advice
