Re: Can This Be Healthy Or Safe ?


Fred,
I didn't check to see if the same vid is on your link.

LINK:

https://www.mandalayhomes.com/

Mandalay Homes in Prescott Arizona is run by a fella that's from the upper peninsula here in Michigan, and I know somewhat.

Anyway, they are breaking ground on a 2900 home dev out there that will be using that process.

He's doing Net Zero homes on a large scale NOW. And he does his homework before putting new tech into production.

Ok, It's a liquid applied sealant, that is like caulking.
Does that mean 5 years down the road the performance will have suffered from cracked caulking syndrome?
I would like to see long term data on one of these homes.

Not bashing the people doing this, I really want to see something like this that works over the long term.

Re: Can This Be Healthy Or Safe ?


This type of product has been used for duct sealing for 20 years. It has worked well, and You'd expect heat to degrade it faster than usual.

Indoor air quality us an issue no matter how you get a tight envelope.

IMO, as soon as existing housing stocks are required to meet current energy code, this is really going to take off, $1000 to retrofit an existing is way cheap.

So this is basically aerosolized pookie?
And how could this have a negative effect on IAQ, after it sets up?

"Pookie" is what we call duct mastic in this part of the world.

Something like that. Whatever it is, apparently it's acrylic.

The product doesn't create the air quality concern, having a tight envelope automatically degrades air quality, so you can get into having ventilators.

That really is something, could really save some contractor's bacon who was supposed to have an airtight home but screwed up along the way.

Re: Can This Be Healthy Or Safe ?


My 25 yo modular home is so leaky, I'd like to find the builder and take out back to the shed for some wall to wall counseling.

This might be the answer I seek. Wonder if I can get in on a franchise?

The thing I like about it is, you can control how tight the house is by shutting the machine down once it reaches you desired air exchange rate.

Re: Can This Be Healthy Or Safe ?


I'm curious about the remodeling aspect, how would it not leave a layer on everything in the house? Unless I missed something

Leave a layer of of what and on where? This is performed during the studs phase.

It's not like Grandma's Duncan Fife Dining room set is gong to be in the house.


smh

I'd have to go back and reread the article, but it talked about doing remodel/retrofit applications. Since it can be done with sheetrock up, does it have an effect on spackle/ paint?

It would make sense that this could only be done in a new construction environment, but I don't recall it specifying that

I actually think this may be the best approach to airsealing an existing. Something like airseal and possibly repaint or touch up.

Re: Can This Be Healthy Or Safe ?


That’s a pretty interesting way to seal the house, I can definitely see a benefit for using it in older homes, but is having a super tight house healthy? I’m a builder in Prescott and we have a lot of radon gas, From what I understand you need air exchange to help mitigate radon build up in the house.

There are specific methods for dealng with radon. And they do not include leaving pulling the windows out and letting the wildlife in.

Do your homework.

PS: Actual home builders know what is required of the homes they build n the state they are in.

If a house fails a radon test, actual mitigation is the only answer.
