SPRAY FOAM

[deepportage01]

IS THERE ANY REASON NOT TO USE SPRAY FOAM INSULATION IN A WHEELED HOUSE? I KNOW ITS A LITTLE MORE$$$ BUT OTHER THAN THAT WHY NOT?

It would the best to use. No need for vapor barrier, better insulation value, tighter house, best to start with the paneling, then wiring and gas lines, then the siding. You be glad you did.

Just for S's n Giggles I bought the biggest can of expanding foam with max expansion and one can did not cover a lot of area. 3'x20" approx. 2" thick pretty spendy at almost 5 bucks a can. I was planning on talking to a company close by,see how much it would be for them to spray it. I would not mind leaving it exposed and "rough" if it looked good and was paintable. It would be like sitting in a cave and fishing, although, it being painted white.

There is a house maker off 94 & 24 in Clearwater. (just south of St. Cloud) North west side of (94) about ten miles that has his houses foamed by some guy.Heavy duty coverage I must say and stiffens up the house in a hurry.

Someone else might be more familiar with the cost but I believe it was like $800. Looks rather rough but if you cut it level and wall your house no one knows anyway.

There are reasons not to use the foam. Urethane foam can trap moisture and over time and may weigh your house down. EPS foam doesn't do this. EPS, commonly pink or blue is a closed cell foam where Urethane expanding foam is an open cell foam, even though they all claim to be closed cell.

"Great Stuff" is water cure Urethane expanding foam. This means that it needs moisture to cure properly. If one was to go out and buy the largest can of great stuff in the world to foam their home, you'd end up with some pretty nasty walls and exterior as the foam would continue to expand with added moisture, pushing the walls out.

Anywhoo, I'd stick to EPS (expanded Polystyrene) foam board. It's light weight and will not trap moisture

I've seen a builder in North Dakota I believe that foam finishes the interior of his houses as well. I wonder what experiences other have had with this method.

My houses have all had the pink board and moisture barriers so I have no hands on experience with direct spray. foaming !!
