No End in Sight for Spray Foam Problems

Goodness.  Over the past two weeks I have been contacted by 5 families living in hotels or rentals because they feel sick inside their spray foamed homes.

As an update: Lawsuits are being filed from three (at least) different firms against manufactures such as Demilec, Icynene and Bayer (to name the top few).

Some families are being paid small amounts compared to what they have lost and have to sign all future rights away.

My roster of foam families keeps growing yet foam companies still have the nerve to deny any issues.

Here is the topper…Dave Lall told me during our phone conversation that it is the installers fault; he even used an analogy of installers cutting corners and hoping not to get caught in order to save money with a guy at a bar taking the last drink his friends bought him before driving drunk home and hoping not to get caught.

Classy Dave, nice work for a CEO.

Also, It is somewhat satisfying to hear that my little blog sends your lawyers to court looking to find ways to get my communications with others.  Perhaps you should spend the time and money on helping people forced out of their homes because they used your product instead of in court asking for my emails!





I suppose this is how it works.





Ingredients of SPF

Below is what Spray Foam Safety had to say about the SO CALLED NON TOXIC SPF….

Spray Polyurethane Foam Chemicals. Link Here

“Chemicals in SPF Products
In order to create the final SPF insulation or sealant product, a chemical reaction of the two component parts, commonly referred to as Side A and Side B, has to occur. SPF products contain approximately 50 percent Side A and 50 percent Side B. This chemical reaction generates heat.

Side A contains very reactive chemicals known as isocyanates. Side B contains a polyol, which reacts with isocyanates to make polyurethane, and a mixture of other chemicals, including catalysts (which help the reaction to occur), flame retardants, blowing agents and surfactants.

Side A contains isocyanates:

4,4′ Methylene diphenyl diisocyanate, CAS #101-68-8
Polymeric MDI, CAS # 9016-87-9
Generic MDI mixed isomers, CAS #26447-40-5
Other similar isocyanates

Side B contains a blend of proprietary chemicals that provide unique properties in the foam, including:

Polyols (derived from petroleum and agricultural sources)
Flame retardants
Blowing agents
Amine or metal catalysts

Industry is supporting development of a standard method for measuring off-gassing of volatile chemicals.

Isocyanate Compounds Commonly Used in SPF and related products
Isocyanates are chemical substances containing an isocyanate (-N=C=O) functional group. Diisocyanates have two isocyanate functional groups. Other isocyanates contain several isocyanate groups.

There is concern for exposure to any isocyanate-containing material related to SPF use, including products that contain only a single isocyanate. It is important to understand the other products that contain isocyanates because if sensitized to isocyanates, even low concentrations of isocyanates can trigger a severe asthma attack or other lung effects, or a potentially fatal reaction.

The most common isocyanate compounds used in SPF are listed in the table below. SPF contains MDI and MDI-based polyisocyanates. There are numerous chemical names and synonyms for members of the class of isocyanates and the list below is not all-inclusive.

Chemical Name

CAS Number

4,4′-Methylene diphenyl diisocyanate (MDI)


Polymeric Diphenylmethane Diisocyanate (pMDI)


Diphenylmethane Diisocyanate Mixed Isomers






Generic MDI


4,4′-MDI homopolymer


Generic MDI homopolymer


4,4′-MDI dimer


Uretonimine of 4,4′-MDI


4,4′-MDI/ 2,4′-MDI copolymer


The world production-volume of isocyanates is estimated to be in excess of six million tons annually with growth of 10 to 15 percent annually. The most widely used isocyanates are:

Methylene diphenyl diisocyanates (MDI)
Toluene diisocyanates (TDI)
Hexamethylene diisocyanates (HDI)
MDI-, TDI-, and HDI-based isocyanates

Isocyanates have a broad range of uses in the manufacture of consumer products, including:

Spray foam
Coatings, e.g., paints and varnishes
Caulks, glues, adhesives
Flexible and rigid foams (used in mattresses, pillows, furniture, automotive seats, insulation, and roofing)

Spray applications of isocyanates may generate aerosols, mist, and vapors that can be inhaled or come in contact with the eyes or skin. Potential exposures may occur through skin contact or inhalation of particulates and dust particles containing isocyanates”.

Great Article from Tascon Industries against using Spray Foam

Aside from the obvious issues with spray foam that I talk about often, here is a great article on why SPF is not a good choice because all of the other dangers.

My blog response on GBA.

Our home was 18-23 degrees during application, all windows closed and we are sure the substrate was far below 50 degrees. The product we used is the product that gets the most complaints here at GBA and other forums. The installer has his lawyer on us, with a lien on our home, wanting to be paid for the rest of his bill. Meanwhile his insurance says they will not cover anything and we just paid more than 60k to remove the SPF in hopes we can get a clean IAQ report. Why does this SPF company keep getting away with this? They are busy fighting many many familes, but all the while deny anything is wrong. I am sure application has almost everything to do with this. These stories and many other families are about to become very public. This is not about getting back at anyone, this is about creating awareness to a product that has turned lives upside down, yet t no one will take responsibility. Instead the homeowner is left with financial ruin and emotional dispair. Not to mention potential unknown health issues. All in the name of ‘going green’. I’d love to see where green fits into the 600 large trash bags of removed SPF from my home sitting in a landfill for 1000 years.
Stay tuned, it is hard for any company to deny something is wrong when a large number of people all have the same story to tell.
Ever wonder how many others are out there that have been paid some money to go away and not say anything about their foam? Think about it, if people go public about bad SPF in their home, their home is forever marked, say good bye to market value. So please consider the ones of us that are willing to be public are REALLY concerned and are trying to find what is wrong. We don’t move out of our homes, throw everything away, live in campers or hotels because we want to. Some of us have new born babies and cannot go back to our home, even after the Spf company has tried to remediate it. We are not making this stuff up. We just want some answers and our homes back.

Power in Numbers


Sooooo….when our symptoms first started when we were in the house with SPF, I questioned if WE were crazy. It is no secret that I am dramatic at times, but my husband, he is pretty anti-dramatic. This was my first red flag (well, aside from the fact that breathing was hard and my eyes and chest stung) indicating something was not right with our new SPF. My husband reacted enough that to this day, he will only stick his head into the front door for a second as he has been advised to stay out of the home.
Dr Carrie Redlich of Yale Hospital is keeping busy with all of us ‘SPF gone wrong’ folks. She is seeing similar things among all of us, so perhaps it will be just a matter of time until a correlation may be drawn. Some of us families have a definite diagnosis and some of us are not there yet. Some of us have big labs testing our homes, some have the EPA researching our homes. Some have had news stations film the demo of parts of their homes,some of us have the SPF installers putting liens on our homes because they think THEY GOT SCREWED. Hey, I’d happily have my installer come collect some of the 600 garbage bags I had to pay to have DUMPED in a landfill for some of my money back (never mind even thinking about OWING YOU more money (BTW, almost all the other SPF homes were done in too cold of conditions). Some of us have big law firms behind us, some have small firms, some are trying to do it without, some simply have to say nothing because all the money in the home would potentially be lost if it was exposed that our SPF was off gassing in the home. Some try to fix the homes, some live in campers or hotels or rentals in order to keep some kind of normal. Some of us have fixed our homes and swallowed the entire financial and emotional burden on our own because the SPF company is just that bad to try to deal with. Some do what the SPF company wants and silently moves on in hopes of getting back to a normal life in another home.
The bottom line is no matter how we individually are handling this nightmare; our symptoms, complaints, and responses from the SPF company are all the same. Something is to be said in the sheer number of SPF families.
