Re: Opinions on polyurethane insulating foam as an encapsulant for remediating and insulation retrofitting older buildings?

The issue with removing any mold is if you don't correct the problem that caused

the mold (mold requires water and a nutrient base), the mold will come back

after time.  Mold whether it is wet or dry (dead) is still allergenic.

What do people think about insulation foam for making getting rid of

mold easier?

[Guest guest]

People allergic to mold spores can also be affected by " dead " mold

spores. llaci

Yes, of course, but I am not talking about the very " best " solution,

so much as an achievable, incremental one.

This isn't for seriously moldy buildings..which need true remediation

or replacement..its for the rest..

the kind of old buildings that get moldy from leaks and condensation..

What use would even a expensive remediation be if then the building is

THEN left without adequate insulation?

Most older buildings have drafts.. and then the mold would right come back.

A clean and foam approach would preventing homelessness and allow

reoccupation in a relatively short amount of time,

preventing people being made sick not just by whatever remaining old

mold exists,

but by wind blowing it into living spaces. Foam insulation done

properly does a lot to address a large subset of mold problems

those caused by condensation.

Water doesn't condense on adequately insulated surfaces and air cant

move rapidly enough through well installed

foam to support virtually ANY particulate movement.

So, its encapsulation, in a sense, but its NOT at all the same kind of

encapsulation that the snake's oil folk

promote, because not only does it stop air movement, it also

addresses a MAJOR CAUSE of mold in buildings, condensation,

It stops the stack effect and drafts, etc, cold, and seals.

Sure, a professional remediation is better, but so expensive that

often, it is avoided for financial reasons.

That COST leads to lots of people being forced out of structurally

sound but neglected homes " for their own good "

when all they wanted when they complained was health and a safe place to live.

Add a $400 ventilation device that allows year round ventilation

without loss of heat and the combination will leave the building

heathier than most new construction..
