Cavity wall insulation blower !!

fred55 · 14 Feb 2022

A question a little off the wood working track but my research has failed so far. I have a few houses that could benefit from cavity wall insulation.
So I'm in the market for a Polyurethane bead blowing machine for cavity wall insulation - I've googled and researched but still cannot find a source of a blowing machine and gun. So could anybody out there point me in the right direct or know of anyone selling kit ? - Before I get the oows and arrrs I am experienced in the building industry and had an insulation company 40yrs ago but opted for buying, selling and renting out. Thanks for any suggestion.

Have you considered a large industrial vacuum cleaner with a reverse/blow function?

Can be ok as you know if the exterior walls are sound and done right but a lot of the concerns were created by cowboys who just filled any cavity they could without the building knowlege. I Don't know where you would get a blowing machine but can say this firm do a good job if it ever needs coming out.

Thanks for replies - thought about making to my own deign - blower for the beads, hopper or suction hose for beads, c/a for the pva glue, gun to mix/inject into the cavity - other stuff I have from my days in construction but easier if I could just buy one, ha ha, that works, Yes agree load of cowboys did inappropriate work just to pay the mortgage, don't get me started on injecting Dpc mostly a waste of money just to get a worthless piece of paper for the mortgage company.
