We listened with great interest to the debate about the Construction Scammers on TV-4, which aired after the first segment about fortune seekers and fraudsters trying to profit from unsuspecting homeowners. In the segment, one of the participants mentioned that there was a significant risk with foam sealant because (if we understood it correctly) you only had a couple of minutes to evacuate the house if it caught fire.

It certainly sounds very worrying if that's the case, as foam sealant is used everywhere today for filling drafty gaps and other spaces that need sealing. Is there any experience with this?
Wondering, two curious DIY enthusiasts. :O:O
 
The flammability probably comes mostly from the solvents used for the foam when it is in the can, so to speak. Dried and cured foam likely does not burn as explosively.
 
Yes, that's why there is non-flammable foam from "real" manufacturers like sikaflex and bostik etc., if you buy cheap byggmax and biltema junk, it's probably cheaper because it's an inferior/more dangerous product.. As usual, you get what you pay for quite simply.
 
Just tried a small piece of cured foam sealant from Biltema. It burned well but not exactly explosively. Like kindling, roughly. My amateur assessment is that it doesn't have any decisive impact in a house with kutterspån in the walls and beams, i.e., like in mine.....:rolleyes:
