    Hey all,

    I was looking through Instagram at a few of my favourite American and Canadian construction pages and this company/product came up. I know its of no use to us lot this side of the pond but its a very interesting concept none the less, I guess its another sign how far behind the British construction industry is! Anyway, have a look;

    I have fallen in love with it, simple and targeted

    Wonder how much it costs per house?

    I have no idea but I read on Instagram that they missed taping up a bathroom vent in one house and it blocked it, that must be a 75-100mm aperture!

    Could this mean - go all the way - abandon all endlessly frustrating attempts to 'build airtight' - just let the builders knock it together 'as normal' - and let AeroBarrier fill all the gaps? (just like the gaps between planks as pictured on their website)

    Vinyl Acetate Polymer = atomized chewing gum,

    got to get me some !

    This took me back 40 yrs when I worked in a DO and the draftsmen used *THIS* sort of stuff...

    https://aleenes.com/aleenes-repositionable-tacky-spray

    Here's another good-looking one, but in French I'm afraid...
    I assume similar products must exist in the Brexiteer domain...

    https://www.sid.tm.fr/produit/aerosol-de-colmatage-et-detancheite-oleospray-G33.html

    (key words to search for: colourless / clear / sealing / aerosol / flexible / surface treatment / invisible / repair ...)

    A US example :
    https://www.devansealants.com/portals/0/tech/401.2%20-%20Thumb%20grade,%20general%20purpose%20sealer.pdf

    Maybe I'll get my blower door motor out of hibernation this Spring, and give some a go round my windows !

    I notice there are no statements about the expected longevity of the product, let alone any published lifetime tests. I think I'd wait a few years before entrusting my build to it. Might be useful in some special situations though.

    PS Does any of the material escape from the house and enter the environment as 'microplastic'? It might bump the cost up if you have to hermetically wrap the house before applying the stuff :)

    I think by it's method of disposition alot of material will go outside before the cracks and holes are small enough to filter all the droplets. Hermetically sealing the outside will mean that the air/sealant mix will not flow through the gaps.

    I would imagine that the loss to the environment would be improved by starting with a low pressure differential then slowly increasing as the airtightness improved. This they would do anyway as it would save on the material.

    If this stuff or any other form of 'flexible air blocker' came in a can I can see builders getting a blower test organised, with a team inside with smoke in one hand and a can in the other. Spray in the general area and let the air flow do the rest. It feels like a bodge and inelegant - on the other hand **IF** it can deliver long term airtightness is it a bodge?

    A whole house solution would be needed for fixing a bad build - but a 'man with a 'can' and blower solution may be ideal for fixing local failings in an otherwise good air barrier.
