Insulation over dormer window & roof

fdiddy · 23 Oct 2023

Hi, I need some advice on topping up insulation in a dormer window as seen in the first pic.should I install right to the wall or stop at the end of the aeroboard?I will be installing 200mm knauff eko.

For pic 2, in between the 2 dormer windows is the roof which also has 100mm aeroboard. Is this suitable or should it be replaced with insulation installed right up to the roof ?to maximise insulation effects
