Listeners write in about ambitious projects and sinking patios before asking questions about old house specialists, attic headroom, and home shops.

FTC Warning: Polyurethane foam produced from these materials may present a fire hazard if exposed to fire or excessive heat (i.e. cutting torches). The use of polyurethane foam in interior applications on walls or ceilings presents an unreasonable fire risk unless protected by an approved fire resistant thermal barrier with a finish rating of not less than 15 minutes. A code definition of an approved "thermal barrier" is a material equal in fire resistance to 1⁄2" gypsum board. Each firm, person, or corporation engaged in the use, manufacture, production or application of the polyurethane foams produced from these resins should carefully examine his end use to determine any potential fire hazard associated with such product in a specific use and to utilize appropriate precautionary and safety measures. Consultation with building code officials before application is recommended.
Disclaimer: This document is prepared pursuant to OSHA Hazard Communication Standard (29 CFR 1910.1200).

ection 5 - Fire Fighting Measures
Flash Point: Not established.
Auto Ignition Temperature: 850°F - 1000°F
LEL: N/A UEL: N/####Extinguishing Media: Use water, foam,CO2 or dry chemical.
Unusual Fire or Explosion Hazards: Polyurethane foams, in common with other organic materials such as paper, wood and cotton, can present unreasonable fire risks when exposed to ignition sources. Once ignited, fires can burn rapidly and produce intense heat and dense smoke. Install foam only after all welding cutting or other hot work has been completed. Do not weld or perform other hot work on foam filled construction.
Hazardous Decomposition Products: Like wood and other organic materials, product can release toxic smoke if ignited.
Fire Fighting Instructions: Water spray, CO2, Foam or Dry chemical.
Fire Fighting Equipment: Because fire may produce toxic thermal decomposition products, wear a self contained breathing apparatus (SCBA) with a full facepiece operated in pressure demand or positive pressure mode.

The way I read this is: the spray foam might reduce the overall fire hazzard of the house due to no drafts, however, once it catches fire there will be a lot of smoke and flames.
If your house was properly constructed the foam would be one of the last things to worry abought. If you use ijoist the FD wont go inside the structure. If the foam is smoking and flaming then the house is alredy toast!
You are both right. I can sleep sound in one and with my customers sleeping in them

My own experience is that it is slow to catch fire if I just hold a match or lighter to it, but if I throw a chunk on the fire, it will give off smoke and flame on.
It seems to be slightl;y more flameable than a two by framing member, but the fact that the tight house from corbond is well draftstopped throughout, there is an offsetting increase in safety, especially when the prodcut is encapsulated behind a gypsum finish panel

All commercially available foams marketed for insulation use have fire inhibitors included in the formula. Of course the foam is flamable, much like the rest of the house.
The code in Massachusetts requires a 15 minute fire barrier over plastic building materials (foam insulation) in the inhabited areas. This is simply 1/2" sheetrock.
So, there is absolutely nothing to fear from the foam itself. The carpet and curtins are much more flamable.
