    My bathroom,an extension at the back of the house, is bloody cold. I know for sure when it was built,about 25 years ago,that it wasn't insulated. I'm fairly sure it was built with cavities, well I hope so,because I'd like to get insulation put in. Not sure what it's called,but you get holes drilled and the insulation pumped in.
    I know some companies do it, haven't bothered checking prices because I'm seriously smashed, but was wondering if any DIYer's here have had a go. Is it possibly to buy the insulation,(I believe it's old newspaper or similar) and perhaps rent the pump. It's definatly something I need to get done this year,won't go through another winter of freezing weather,inside!

    It's not a DIY job, unfortunately. The products (there a several- "Certainfil", "bonded bead" "blown fibre" etc) should be Agrement approved and installed by licensed operatives who are trained. They must inspect the walls to ensure their suitability for pumping and check during the work to ensure a full fill of the cavity.

    Thanks for that jack of all. Just did a little search and I see that the term cavity,refers to a block and brick build with a 'cavity' in between. In my case only cavity blocks were used,is it still possible to get insulation injected in that case.

    I've heard of it being done, although I'd question it's effectiveness and the risk of problems with water ingress, your best bet in this case is to dryline and insulate the interior.

    It can be done but has negligable insulation effect! If thinking of internally insulating (dylining) then make sure to leave a 50mm ventilated gap between insulation and wall otherwise the risk of mould growth is very high.

    Elaborate on which part, negligable insulation effect or mould growth?
