I believe there are instructions on the can that give suggestions.

I like the stuff, but after using it, the tube clogs up. Does anyone know how to keep it clean for future use?

A warning for all. Every can of spray foam I've used needs to be held upside down in order for the spray to work properly. Otherwise you just release the propellant and then the foam won't come out and you need to buy another can. I'll give Tim the benefit of the doubt that that can uses a different propellant and he's using it correctly but as Tim says, read the directions for correct use. Oh yea, the only thing worse then spray foam on your skin is roofing tar. Wear gloves.

yes some have fire rating i know everbuild makes one called firefoam

They are still flamable after they have cured.if caught on fire they stink like toxic thing and burn for 3-4 seconds in each spot.then the fire stops.its not so easy though to set it on fire

I am quite certain that some types are. There are foam products that do have fire ratings. They are used as approved fire blocks around pipe, wire and duct penetrations in wall plates.

Question: I know (from past experience) that it's extremely flammable while installing: Is it still highly flammable after it has cured? Thanks!

I understand your position, and after talking to my supervisor, our company has not made any adoption of foam insulation in the installation method. Our warrranty simply states that no foam insulation can be used otherwise the outcome will be a voided warranty. I understand what you are saying. But getting our R and D department to adapt something and change warranties is a little more difficult. I just thought I would give you a heads up.

AsktheBuilder (November 30, 1999 at 12:00 am)

I am not aware of that. Why would the new foams void the warranty? They are now flexible. The old foams were indeed a problem, as they cured hard as a rock so to speak. The new formulations are made for doors and windows. Is it time for your company to re-evaluate the new foams? I wonder.....

Hello, I am a warranty service tech for a large window company. Are you aware that using foam insulation around our vinyl windows will void your warranty for any problems in the future?
