Re: Thinking Of Adding Spray Foam To My Business


I read a few weeks ago that fire departments are calling for the outlawing of spray foam. Is there any traction on this?

We've also been trying to outlaw trusses, see how well that worked

I don't care either way. Just read something and then saw a snippet of it on the news about the off gasses during a fire and how quickly it can burn.

I think its hard to beat the advantages of spray foam and a quality sealed house.

Although there are some kinks still being worked out between off-gassing and poor installs due to under trained or careless "professionals", I think its like most things that long term they will produce better products that in the end are safer then most of the products out there right now.

Although I can understand the flame spread, black smoke, and issues caused with a fire, reality is most houses aren't burning down and most foam is being used on new construction where the materials in general are providing a safer home that is less likely to burn down.

Re: Thinking Of Adding Spray Foam To My Business


I dont see a change coming based of fire issues. If that were the case, fiberglass would no longer be in existence, nor cellulose based on cases from years ago. And spray foam is FAR from a new product like most seem to believe. There have already been vast improvements as far as the off gassing and flame spread from the product used in the 70's-80's, and even the 90's. However, I am hoping that more pressure is applied as it would be much easier to justify bringing in my own foam division without having to purchase and maintain all the other moving parts, such as consistent fresh air supply and the extreme prep work to contain the jobsite. Hell, just make it easier to clean up and I might smile a bit when I sell one of these jobs!

Not that I know of. There was no mention of this at the recent SPF convention in Palm Springs last week.

The flame spread of SPF is less than 25. Wood has a flame spread of 100. In many cases, SPF makes the house more structurally stable during a fire, due to its inherent strength and resistance to heat transfer. Fiberglass just melts.

Here it is now code to insulate basements with r-13 minimum. If you use spray foam you also have to drywall it. Reason being, spray foam puts off a carcinogen in the event of a fire. PIA for people who want the foam but don't want to finish their basement.

Foam is big around here. Now a lot of new construction is using open cell foam and filling up the whole cavity.

Spray foam can be coated with 12-15 mils of intumescent paint such as DC-315 to achieve a thermal barrier. Drywall is not needed.

As to the carcinogen hyperbole, your couch, carpet and easy chair all emit the same noxious fumes as SPF in the event of a fire. Only difference is, the insulation is shielded behind drywall or a thermal barrier and the couch is out in the open.

The reason that foam is popular in your area is because it works - and works well. In the rare event of a fire, we have found that SPF holds the structure together longer due to its strength and air impermeability. That translates to a much delayed structure collapse (roof. walls).

Have fun!
