I saw on TV last night a new technology for air sealing. The put your house under positive pressure, and then they must put some particals into the air that then plug up the openings where drafts occurr. I wish I knew more about it but is anyone familiar with this product? It would be great for my current home

AeroBarrier (tm) essentially the same technology & goop as the Aeroseal (tm) duct sealing system:

It's probably NOT something you would want to do for an already-finished house, but may make sense in new construction as soon as the shell is complete.

Wow thanks. I'm going to look into this, although it's so new I doubt it's available in my area. I haven't had a blower door test done but I know it's bad!

They've been doing duct sealing for ages.
This is just a modification of that tech.

And the face-slapping part about it is that it's such a simple idea.
You do your regular air-sealing and get all the really gross openings closed up.
Then, instead of going anal on your detail work, you use this to close up pretty much everything under a half inch.

I you do this in an already finished house you're going to have a tacky film of gluey-stuff on all sorts of surfaces, some of which might not be readily cleanable. This is really for new construction, PRIOR to painting/finishing out the interior.

Exactly. If you're gutting a place, or doing new construction, you should be good.

Now, it MIGHT be possible to do individual rooms this way (this is how they obtain coverage). But you'd wanna talk with your contractor for that.
