There are some spray foam manufacturers and sellers who claim the use of polyurethane foam as an insulator in the home can reduce heating and cooling costs by 30-50%. Of course the actual savings is based upon so many factors, unique in every application, that we couldn’t possibly speculate as to the accuracy of those figures. What we do know, is closed cell spray foam insulation has an R-value of 6.7 in one inch of cured foam. That is a hard fact, no matter what the application.
However, what most people do not know is spray foam insulation can be used very effectively in applications other than walls and attics. It is true, the insulating, sound proofing, sound deadening, moisture resistance, sealing, insect and rodent resistant qualities of polyurethane foam kits are beneficial to so many more areas than most people think. Let’s take a look at all the potential applications for spray foam insulation; no doubt there will be a few that even the most seasoned contractors have not thought of!
Aside from spraying attics and between wall studs, consider insulating the home’s rim joist. By doing so, the interior cavities are better protected from cold/hot air penetration and critter invasions. Crawlspaces are fabulous places for using polyurethane foam; drafts are blocked, insects are kept out, moisture cannot build up and extensive flood damage is prevented. Now how about those older homes where the water pipes are on the outside of the building and at risk of freezing in the cold of winter? Consider the benefits of insulating them with spray foam. Some extreme temperatures will not be suitable (-200F or +200F), but 99% of residential applications will reap huge benefits from this application.
Now contemplate the recreational elements of the home, such as pools, spas, boats, recreational vehicles and trailers. Reducing the costs of heating your pool water by up to half will be easy if the underlying cavity and sides are insulated with polyurethane foam. Campers and trailers are rarely insulated beyond a cursory overlay, resulting in diminished use during the spring and autumn months. Why not extend your annual use of recreational vehicles by adding a layer of spray foam insulation? Plus, don’t forget the spray foam will also help deaden noise from the road. Pleasure boats, dinghies, even yachts can benefit from polyurethane foam. Aside from the insulating qualities, there is added buoyancy. For small vessels like row boats and the kid’s summer dinghy, that could be a great added safety benefit.
