I've just had a warm deck put on my new extension.
Within the walls is 100mm dritherm & celotex is on the roof.
Before the inspector comes I'm wondering if the gaps between the joist, that sit on the wall, need filling.
I was gonna cut celotex and push in the gaps. Is this sufficient for building control. The roofer said it would be fine but would it be better to use thermalite blocks to offer more support to the joists?
Here is a pic, any advice is appreciated.
Thanks
