Spray foam insulation combines and applies isocyanate and polyurethane liquids to a surface. These chemicals in the foam expand quickly into foam that sets over a large area to create an airtight seal.
In the recent past, spray foam was the insulation choice of many
property owners and construction professionals. Why? Because of the foam's
ability to give full-proof insulation against damaging moisture, pesky bugs and
air drafts. The spray foam significantly lowers a homeowner's energy bills.
However, recent discoveries prove that improper spray foam
insulation can cause a downside ripple effect that could ultimately devalue
your property. How?
1. Higher levels of toxicity
First, spray foam chemicals are harmful during installation and
can cause serious health problems if not handled professionally.
In cases of improper spray foam application, for instance,
exposure to loft insulation spray before
complete curing can lead to long-term health problems such as asthma. Mortgage
lenders know these health risks and will not want to invest in property with a
lower Return on Investments (ROI).

2. Airtightness
The perfect level of airtightness that spray foam offers requires
a well-ventilated home. Without proper ventilation, moisture that accumulates
indoors will have nowhere to go and will damage various surfaces inside the
house. Financial lenders don't want to take on these future damages, so they if
they will extend a mortgage offer to you, they might ask for a discounted value
for your property.
3. It is permanent
Spray foam insulation is permanent. This permanency means that if
you later discover problems caused by incorrect installation, you must enlist
the services of a spray foam removal company. Otherwise,
suffer its effects, such as foul odors, for a long time, which may eventually
make your home uninhabitable.
Conclusion
If you must have spray foam insulation, enlist the services of a
professional. Otherwise, the health risks and cost implications associated with
the incorrect installation may far outweigh any potential benefits of spray
foam insulation.
