Cavatiy wall insulation - Liquid foam?

Fanny Biscuit

I'm looking for opinions on anyone who has had their house -cavity walls insulated using a liquid foam as a option. I am looking to get this done and have come across a company who use this method. I am just not sure and would like to hear a few opinions for people who may of had this done.

The house is a 3 bed end of terrance if that helps.

Ask the company for the IAB or BBA certificate to show the suitability of the product in the Irish or British climate.

Personally I have not yet come across such certification.

i know that you will have to get each row drilled and sprayed horizontally if you know what i mean, and with that it still may not fully fill because of mortar being dropped between blocks when built, and even at that there will be alot of cold bridges, im thinking of doing this and externally insulating too. but it has to help as cavity blocks seem to be the hardest to insulate

I understand, it is an expernsive form of insulation but its best thought of as an investment. With cavity blocks its the only solution i would be happy with myself.

cavity blocks should not be filled.

you would actually be making the situation worse by filling.
the link above describes why.
