Cavity wall insulation options

    Ive been looking into getting insulation pumped into our house. Ive read a bit about the various options but would like some advice.

    I liked the look of foam insulation because of the air tightness and small drill holes( i have red brick to the front) but it isnt certified for use in cavity walls and so would not be elligible for a grant. Is this correct?

    Would it be more or less likely to cause problems with moisture getting to the inner block?

    Any recomendations for good companies in dublin north side. Pm me if its not permitted to post company names in thread.

    What are the options for a full full cavity?

    Are there not products available that have nsai and agreement certification?

    i don't know, im not aware of any full fill system used with brick - I always thought where brick is concerned the cavity was more relevant. perhaps some cavity wall installers out there would comment. I be very wary is there's not an Iab cert

    Section 3.11.1 (it continues onto page six) would suggest in certain parts of the country a brick outer leaf is ok. Those areas classified as 'Normal Exposure'. Am I reading this correctly?

    normal exposure - so for the most part the system is only acceptable in leinster:)
