Cost of Spray Foam Insulation for Existing Houses

Improvement.com and HomeAdvisor.com 2017

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.

National Cost of Spray Foam For Existing Homes

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:

  1. What type of portable spray foam equipment did the contractor use for these types of projects?
  2. Did the contractor make any money or did they do this in conjunction with adding other types of insulation?
  3. What type of contractor was this?  Are we talking insulation contractor? Spray foam contractor? General contractor?
  4. 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.

Can You Turn Drywall Into An Air Barrier?

Bill and Clay test the Spray Pods Gun and try to find out

Welcome a brand new Spray Sealant Blog post and today we are excited to show you our new video format where we are attempting to give our viewers a more complete picture of how our ground breaking spray technology works. It’s one thing to talk the features and benefits of how something works. It’s an entirely different challenge to actually go out into the real world and make it happen. It was once said that everyone who has ever taken a shower in the morning comes up with a great idea. The question is whether you can towel yourself off, put your clothes on and then go out and actually execute that idea to see if it works in the marketplace.

On this post you will watch Bill and Clay and they take the Spray Pods Gun out to a job site to see if they can use a 24oz can of Drywall Spray Adhesive to create an air barrier using common, every day dry wall or sheet rock. Since dry wall is one of the last building materials that is installed in a new residential house that is in the conditioned space, the opportunity to air seal the entire wall means that areas that may leak air that were not addressed during the assembly of the wall could in fact be sealed when the dry wall is installed. This possibly opens up a new opportunity for dry wall companies that want to add air sealing to their business revenue.

What Is A PolySealant?

This Spray Technology Has Tons Of Applications

What happens when you blend the efficiency of closed cell spray foam and the durability of sprayed polyurea? You get polysealants! Polysealants from Sealant Technologies, Inc expands during installation to fill cavities, gaps, cracks and penetrations throughout the building envelope. Polysealants help block air infiltration, enhance thermal performance and manage moisture on insulation jobs of all sizes. When these air sealants are sprayed, they create an airtight and moisture-resistant seal using two components that quickly bond to common building substrates for a flexible, long-lasting seal. Using a spray sealant to bridge the gaps in a building envelope or other structure can bring significant heating and cooling savings through reduced energy usage.

So what is an polyurethane sealant? A polyurethane sealant is an elastomeric material that allows for 25% – 50% movement. Sealants are used to fill gaps, to keep water and air at bay, to allow for expansion and contraction of building materials and to enhance aesthetics. Silicone and polyurethane are two popular types of sealants. Despite their common purpose, there are major differences between them.  The primary difference is at the chemical level. Polyurethane is an organic material. Silicone is an inorganic material. The effects of breakdown of silicone and polyurethane depend on the sealant’s chemical makeup.

Spraying A Brick Wall

Brick walls are sturdy structures that are not only functional in weight support, but ruggedly aesthetic. Brick walls can be found inside a residential dwelling, separating two rooms or as an exterior facade. However, brick is porous and is not easily sealed. Moisture can easily seep into a building through a brick. To prevent moisture, which can lead to mold and mildew growth, you’ll have find a way to seal air in order to stop the air transfer which is what a good air barrier will do.

Spraying A New Trailer

You don’t think about it much until you are about to purchase your next trailer or container and you begin to look at how they are constructed. The challenge is that in a lot of cases, most are built with cheap materials and the entire system leaks air. Like your house, if the trailer isn’t tight and if there isn’t any effort to make that trailer or container one solid envelope, then in the long run, it won’t work effectively.

Spraying An Old Wood Kiln

A conventional kiln is relatively simple to operate and maintain and it is a cost-effective technology for wood drying. The downside of this technology is energy efficiency. A conventional kiln consumes around 50% more energy than that required to evaporate the water. Energy consumption in a conventional kiln is required for moisture evaporation, heating the kiln and lumber, kiln ventilation, thermal losses, air leakage, and air humidification. Air barriers are effective ways to bring energy efficiency to any older wood kiln.

Spraying PVC Pipes

In the plumbing industry there’s been a way to prime and seal pvc pipe. It’s understood that “this is how you do it”. You purchase two cans of liquid; one primer and one cement, or plumbers’ glue. You open the primer and swab it on. You then open the cement and swab on the cement. AireBarrier does not work that way. A thin coat of this new sealant technology will create adhesion and block air and all of this can be done quickly at an affordable cost.
