    Hi all have a small lean to on the back of the house - it's about 3m square. Leads off our kitchen. The kitchen is freezing.

    Anyone recommend someone to pump this? Walls are cavity block, dry lined internally with Rock wool, so not the best.

    Cavity wall? Or cavity blocks?

    If the latter there is no point pumping. Remove Rockwool and put up 62.5 or larger insulated slab. Take care of Airtightness at the different junctions.

    Thanks for the reply. My query was to pump the roof void - the attic of the lean to as such - so on plan an area approx 3m square. I'd do this first then see if the walls need redoing

    dont pump the roof, adding insulation without understanding the vapour path and ventilation requirement is a bad idea
