I'm a contractor and very willing to do it myself. So far, when looking at closed cell foam, I've been unable to come close to the cost of fiberglass ($0.30 for walls and $0.75 for ceilings). Thanks, Don Where can I find low cost closed cell foam? I’m a contractor and very willing to do it myself. So far, when looking at closed cell foam, I’ve been unable to come close to the cost of fiberglass ($0.30 for walls and $0.75 for ceilings).

The trade off for a tight home is that we need mechanical systems to bring in and remove air.We exhaust air in bathrooms and kitchen hoods which remove odors or fresh air for gas appliances and are important,so any air removed from the home has to be made up.If the home is in a negative pressure then the air will be brought in through any leaks in the building envelope.If that air isn't conditioned we loose the energy rating we are trying to accomplish.The mechanical systems need to be maintained to the nth degree.The home will be very cheap to operate,but will need more attention to maintance on the mechanical equipment.But just because the home is very efficiant doesn't mean its worry free.In fact it may be the opposite.The overall payback is well worth the effort for all of us.
