Foam insulation - do it yourself? Pros? Cons? Safe for hot water pipes and wiring?
A while back I watched a show called "Off the Grid" with Les Stroud. He renovated an old house in the woods, and one of the upgrades was full insulation using spray foam. It seemed very like an easy thing to apply, and it fit every nook and cranny.
* Is that something I can apply myself?
* What are the advantages of spray on foam over fiberglass?
* Disadvantages?
* Is it safe for hot water pipes and electric wiring to run through the foam? My pipes and wiring run through my attic joist bays and wall stud bays, so this would be unavoidable. Is this stuff fire resistant?
