What about those certified magic insulating paints. They have those in Europe and the US but I heard from a painter friend of mine that the reason they aren't in NZ is because branz knows snake oil when they see it and have the balls to say so

I note that you have the Airfoam website shown when talking about spray on insulation. Airfoam Wall Insulation is not a spray on insulation, but an insulation designed specifcally for the insulation of existing walls of houses built prior to 1991. A common misperception about Airfoam is that it is similar to the polyurethane foams that are used as spray on insulation. This is incorrect and because Airfoam is "Hydrophobic" it will not result in condensation build up within the cavity. What hydrophobic means is that the Airfoam product will repel liquid water, yet allow water vapour transmission, in other words it continues to allow the walls to breathe, hence no condensation build up. Airfoam has been successfully installing insulation into existing walls for over 30 years without any major problems.

Ouch - I guess Airfoam hope not too many people read the BRANZ report, its pretty damming. I'm sure Airfoam have the best intentions, but its maybe always going to be a second class insulation solution for old ladies who don't want the disruption of a proper strip out, insulate and reline. They even sometimes insulate your kitchen drawers for free, see pic ;)
As far as BRANZ is concerned, of course they don't have the resources of larger organizations in larger countries. But, all research is useful to us average Joes, and IMHO the Airfoam report seemed pretty professional.

wasn't BRANZ complicit in leaky homes?
However - we had our SE Auck 1950's weatherboard house wall cavities foamed by Airfoam - it has made a spectacular difference in comfort and dryness to our house - no more mould in our sth facing rooms and almost non-existant condensation
Airfoam has it's place - BRANZ were being more than disingenuous with their investigation and report - smacked of them needing to make a bad report on something to improve their bad image.

Yes, I heard that BRANZ has been going around drilling holes through the cladding and building wrap and that's what caused all those houses to leak. I presume Airfoam repaired the building paper in your house before they left. Perhaps your a little concerned about what will happed when you go to sell your house. Never mind you can aways resort to blaming BRANZ for you gullibility.
Amazing how adding 200+ liters of water to your house ended up drying it out.

BRANZ are celebrating their 50th anniversary this year. Leaking building syndrome was developed on their watch. What else do you need to know? Why would take their advice?

People make mistakes - perhaps they have learnt from theirs. Either way, why would you take the risk. We looked into airfoam prior to the branz report and the fact they they drill through the building wrap and then fill the vent/drain cavity (in a veneer home) was enough to put me off. Common sense tells you that this cant be a good idea. Remove the wall linings, insulate, and reline. Not as hard or expensive as you might think and you get a new looking room.
