I ran across an article which was published recently and it stirred up my curiosity regarding what the average cost of a spray foam project could be for an average existing home. This lead me to several very interesting sources, one of which I am sure you have heard of. Both Improvenet and HomeAdvisor publish some very interesting data.

Like any project or insulation type, the specific cost of spray insulation varies greatly according to the size of your home or room. There’s more to applying spray foam insulation, however, because you may need your installer to add more than one layer of insulation to meet your home’s energy needs. Each layer of spray foam is one inch thick, and most spray foam insulation installation prices are based on the number of layers of one inch of foam you need in a given space.
So how did they get this this data? It turns out that homeowners visit ImproveNet.com to find a top-rated pro to complete their home improvement project or repair. Once their projects are completed, the members log in to their accounts and complete a short cost survey. After compiling and organizing the data, ImproveNet.com then issues the report on their websites so that people can get a feel for what to expect to a project like this.
While I recognize that this information is extremely unscientific, it does lead to some very interesting questions:
- What type of portable spray foam equipment did the contractor use for these types of projects?
- Did the contractor make any money or did they do this in conjunction with adding other types of insulation?
- What type of contractor was this? Are we talking insulation contractor? Spray foam contractor? General contractor?
- Did this lead to additional business opportunities for the contractor?
So many times it seems that spray foam for existing home retrofitting is used much more as a band-aide than as a leading technology. Granted, nothing in the insulation material space is very sexy and no one thinks about things like leaking air unless some type of professional is able to make the case for solving the issue, but just maybe there is an opportunity for a portable spray foam system that could allow contractors to take advantage of these opportunities, especially of the they can get in and out of the project quickly and without a high capital cost.
