Went to the Orlando home show yesterday and saw some nice displays of energy conserving products. My home is 15 years old and block construction. A few years ago I had foam insulation blown into the block walls and saw a nice return via lower electric bills. I also had a new AC system installed that is a 14 seer in 2006 so I'm covered there. I want to do the next improvement and I believe it should either be new windows or insulation in the attic. The same company that did the foam insulation in the walls now does foam on the bottom side of the roof. Looks like between the closed cell foam base and the top coat of open cell you can get a R24 insulation value. An added plus is the base coat of closed cell is also waterproof which is a plus in our hurricane region. For the size of my house ( 1880 sf ) it will cost aprox. $2500.00 - 3000.00 I just talked rough numbers with the guy at the show. Now lets talk windows, my home has 11 windows with 3 of them being arch top so multiply by a cost of aprox. $200.00 for each and the added cost of custom arch top the cost of replacing all the windows is about the same as the roof insulation. So which is the better bang for the buck ? And what rebates/incentives are available for each ? You guys should know my current windows are builders quality single pane and the roof insulation is blown fiberglass over half the house aprox. 4-5 inches thick and rolled fiberglass over the other half ( vaulted ceiling ) aprox. 5 1/2 inches thick. Obviously I would keep the exisiting insulation if I go with the foam. OK guys fire away with comments.
