Looking for recommendations for cavity wall insulation

Has anybody near Ipswich got a recommendation for cavity wall insulation installers please? We may need this doing. We're replacing the 1960s tiles on our house so have to make sure we have sufficient insulation to comply with building regs. Want to avoid external and internal insulation, filling the cavity is our preferred option.

    Is it definitely a cavity wall under the tiles hanging? A lot of 60's and 70's tile hung walls are solid.

    We're hoping so. Builder thinks so, coming back to cut out a piece of a block to check. Tiles are all off now, so no going back to the 60s.

    dont do it, more issues with damp with cavity flllers. Look at any other method like Wycamol inner fleece.

    It did turn out to be a cavity wall which is being filled as we speak with the white fluffy stuff. Nice chap from Colchester, nobody more local available.

    Well, I tried to, but Search doesn't come up  with anything. The nearest I can see is a ISO-Therm, a 4mm thick sheet material.

    And 4mm is just not going to be thick enough to provide any worthwhile level of insulation. If you want to cover over cracked and/or grotty plaster, it will do the job, but there are cheaper options out there.
    If you want to insulate a wall and save money on heating, do it properly with the right materials. Don't try cutting corners using questionable stuff that make outlandish claims in the advertising.

    Any language construct that forces such insanity in this case should be abandoned without regrets. –
