DIY spray in foam insulation
I started replacing the siding on a pickup bed camper and when I got
the siding stripped down I found the fiberglass insulation was not in the best shape. I was thinking of trying one of the DIY kits of polyurethane spray in insulation instead of putting back more fiberglass batting. Ive read the brochures but I wondered if anyone has had any first hand experience using it. It looks to me like you just keep spraying in thin layers , let them expand and set then do it again to you get the thickness you want. I was looking for the gotchas. My plan is to set the tanks up on a work table with casters and have the wife push it around the camper following me. Hopefully once we start we can just keep going until its done. Since the framing is 2 X2 I figure two passes should be enough. Jimmie |

Cheap, easy, and effective. |

Triple expanding foam, used around a door frame or windows might cause the frames to bow. http://www.greatstuff.dow.com/products/index.htm |

DIY spray in foam insulation
Why, I don't think you are going to gain anything and its going to cost a
ton of money over just using rigid or just more fiberglass. It may have a higher r value but overall its not going to make much of a difference. "JIMMIE" wrote in message ...

Jimmie I rebuilt one before and had it sprayed by a professional insulation contractor who happened to be working in the neighborhood. The spray foam adds a lot of strength to the camper. It also seals the heck out of it. If water gets under the siding this time it just wont matter. The best price to have it done is $500 I could DIY it for $300. Jimmie |
