Spray Poly

Our Love-Hate Relationship with
elcome to part one of a four part
series on Spray Polyurethane
Foam SPF Insulation. Spray poly-
urethane foam (SPF) insulation –
the best thing since sliced bread,
the greatest energy saving "Green" insulation
available, right?
I can't remember another building product with
such a clearly defined love or hate following.
When I say "love" SPF is typically described
by the "Green" movement as I described it
above: safe, energy efficient, "Green," and
even healthy. That's right, it's often touted as a
product that will improve your indoor air quality.
These guys are hard-core supporters and be-
lievers, a solid mix of manufactures, applicators,
builders, and homeowners.
But if you're on the hate side of the issue you're
just as emotionally involved in the product, you
just see things from a different perspective.
Often the hate side of the love-hate relationship
