Are building inspectors and cavity wall insulation?

I've got mineral wool but if I'd to chose again I'd have poly bead. Not because there's any great difference in how they work but they have to drill about a thiird less holes so it just looks better. It'll cost more but you'll still not have to pay the full cost because it's covered by CERT payments.

Just makes sure they put the glue in at the same time - otherwise you'll change a window and need to do the cavity all over again! :rotfl:

Remember you allowed to add the removed glazing area to your 25%, so if you are taking out a window in the walls that are covered by the new extension the area of that is added to your 25%.

actually i am not taking out a window a such except that which is sited with a kitchen door on the section of exterior wall which will be removed anyway.The existing small kitchen will form part of a new extended living area,the only other glazed area is a pair of patio doors leading into the living room next to the kitchen which will stay put
