Protecting a home with spray foam insulation will cost the owner of an average-sized home around $1,600. In contrast, fiberglass batts will run a homeowner up to $600 per 500 feet. Thus, in terms of installation costs, fiberglass insulation is the clear winner. A myopic focus on installation costs, however, can end up costing you money in the long run. Though you pay more for it, the superior characteristics of spray foam insulation can end up saving you money in the long run.
Over time, sprayed-in paper or fiberglass insulation will settle. As it does, its ability to retain the temperature inside your home will diminish. Thus, you will have to inspect your insulation from time to time and add more insulation when needed. This is easy enough to do when you are spraying insulation into an attic, but if the insulation inside your walls settles, you can have an uninsulated gap at the top of your walls and no way to correct the problem without tearing them open. Spray foam insulation, in contrast, will not settle. You will never have to worry about whether or not you should add more insulation.
When contractors build the frame of a house, they are not necessarily thinking about how difficult it will be to add insulation. House frames are full of tiny nooks and crannies that can be difficult to stuff with batt insulation. On the other hand, installers can easily direct their nozzle into these small gaps and once inside the foam will expand to fill the space. You should end up with a more consistent barrier.
Because of the advantages discussed above, spray foam insulation will create a more effective barrier between your home and the outside world. You should have less energy transfer through the walls of your home, which means your HVAC system will have to run less often to condition the air in your home. This will save wear and tear on your system, help to conserve earth's resources, and translate to savings on your utility bills.
If you are looking for a good insulation for your home, you should look beyond initial costs. When you spend more money to buy a superior product for your home, you get extra value for the extra money you spend. By helping to reduce your energy costs, spray foam insulation will be the cheaper choice in the long run.
