sealed home will not meet the required ventila-
tion rate and will require outdoor air supply. De-
pending on where you lie this may require the
use of an ERV (energy recovery ventilator), an
HRV (heat recovery ventilator), or a mechanical
dehumidifier. All three will require alterations to
your homes HVAC (heating, ventilation, and air
conditioning) system.
If you want to know what it takes to properly
inspect applied Spray Polyurethane Foam Insu-
lation, the article titled "Inspecting Spray Poly-
urethane Foam Insulation What to Look For" will
be perfect for you. So you have an issue with
your installed SPF, what is your next step? Do
you hire a chemist? An IAQ indoor air quality
consultant?
Well, I believe you should hire someone who is
extremely familiar with inspecting the SPF. Not
just someone that has performed several SPF
inspections, but someone familiar with SPF.
Yes, there is a substantial difference. Many
who provide SPF investigations never look at
the SPF, they simply collect air samples and
declare the product as dangerous and in need
of removal. While SPF can be misapplied, the
issues with SPF aren't always the result of mis-
applied SPF. This article will help clarify who
and how to properly inspect your installed SPF.
Stay tuned for great information regarding the
use and misuse of Spray Polyurethane Foam
Insulation.
