Are all Foams
There are many types of foams developed for many different
Types of spray foam
It is important to fully understand the foam industry so you
don’t use the wrong foam or have someone apply the wrong foam
in your project. Not only do you need to choose the right
density of foam you need to fully evaluate the Manufacturer of
each. There are many new manufacturers of foam that have
popped up in the past 3 years and many of their foams seem to
be not ready for market. Some foams experience shrinkage or
problems cracking after 3 or 4 years. Make sure the foam you
spec has not been reformulated in the past 5 years.
Everyday inferior, experimental foams are being sprayed in new
homes and buildings. It takes many, many years to perfect the
blending of all the chemical and natural ingredients that make
up the foam recipe. Some of these foams are being made by
companies that are trying to get into the foam business
because they see the potential or are losing market share
because of their traditional insulation is being lost to foam.
Our industry is young we still have no real state or federal
guidelines in place to police the foams that are being
formulated and applied in our buildings today. Most of the
information we see from the new foam companies are just plain
wrong, misleading or incomplete. What can you do? You must
turn to the International Code Council.
The best Foams with perfected chemical formulas (or recipes)
have been tested or approved by the ICCl. IT’S VITALLY
IMPORTANT YOU KNOW THIS INFORMATION WHEN SELECTING WHICH FOAMS
TO SPEC IN YOUR PROJECT! The ICC evaluates products to
determine if all their ASTM test information is correct, and
has not been falsified. (Anyone today can type up an official
looking document.) They also evaluate the products to ensure
that it can be installed according to International Building
Codes. They specify if certain restrictions or exemptions to
code may apply. If this process has been successfully
completed by a manufacturer, they will be issued an ES-Report.
If you are looking at a foam product, you should go to the ICC
website (link) and see if that product is listed. There has
been at least 40 different foams submitted to them and only a
few have passed the tests.
Some manufacturer’s tend to “market test” their foam which
means they put it out for a few years to see if there a
problem develops. If so they try a new formula. They submit
the perfected formula for testing after they have found the
problems have gone away. They used you and your building to
perfect their formula. This can leave an architect vulnerable
to a lawsuit in case of a fire or some failure on the part of
the spray foam. We have many times in the past been hired to
fix the problems of a contractor who has since gone out of
business. It ended up costing the customer money and the
architect some credibility since he/she included that product
without checking into its viability.
