    I'd imagine if you've gone with 200mm cavity you may have originally planned to pump the cavity with bonded bead?

    The cost difference will soon be absorbed in labour costs of fitting the Xtratherm, bear that in mind.

    Every insulation product is only as good as its installation. If your doing it yourself then no better way of ensuring correct fitment/full coverage.

    Id say choose as much as you can product wise that you can install yourself, great way of managing the pennies.

    Can I ask did you have to thicken the inner leaf to wider block with a 200mm cavity?
