Spray Polyurethane Foam

Comfort Seal Insulation uses a water-blown open-cell .5 lb foam that performs well in a wide variety of applications. It has an R-value of 3.8 per inch and is Class 1 fire rated. Spray foam insulation is a two-part, soy-based product installed by Certified Dealers using custom designed application equipment. When installed, expands to completely fill all voids to effectively seal against air infiltration—often the major source of heat/cooling loss. Our insulation also provides superior acoustical and thermal performance when compared to other insulation products. While offering superior performance in conventional construction, it is especially effective in steel-framed structures, older homes and metal buildings.

Our .5 lb is applied by spraying liquid chemical components onto open wall, ceiling, and floor surfaces; or into wall and other cavities. When applied, the components quickly expand to make a foam layer of millions of air pockets—covering surfaces and filling cracks and voids. The foam adheres to almost all surfaces, and when cured can be trimmed off to provide a surface that is ready for drywall or other finishing.

Our 2 lb spray foam is designed as a high performance building envelope insulation system for both residential and commercial construction. It's unique characteristics makes it a structural product that outperforms most insulations in metal buildings, crawl spaces (such as subfloors), and refrigerated cold storage facilities. 

This spray foam insulation is a two-part, soy-based product installed using custom designed application equipment. Most closed-cell foams still use chemical blowing agents, such as HCFCs-- a known CANCER-CAUSING AGENT, so our foam is more environmentally friendly. It also is an air and water barrier and is Class 1 fire rated. The 2 lb. closed cell provides exceptional performance in reducing heat transfer, moisture gain, and improving racking loads. It is applied by spraying liquid components directly onto wall, ceiling and floor surfaces. When applied, the components quickly expand to create a foam layer covering surface, filling cracks, and sealing voids. The foam adheres to almost all clean surfaces and when cured can be trimmed as desired. Also, the foam makes an air and water barrier.

Our focus is on the building envelope and integrated energy systems, and our products are biologically-based polyurethane spray foam insulations. Comfort Seal Insulation is exclusively available. 

What is the Difference between Open-cell and Closed-cell Polyurethane Foams?

When it comes time to actually having the foam product installed in your home or commercial building, you must identify whether you will use 0.5 lb./cu. ft., open cell foam, or 2.0 lb./cu. ft. closed cell foam. This makes a big difference in cost, application methods, and performance.

With the open-cell vs. closed-cell issue, there are two major factors to understand and consider. The first is the nature of the foam. It is either open-cell foam, where the tiny cells of the foam are not completely closed but are broken and air fills all of the “open” space inside the material. This makes the foam weaker or softer feeling than closed-cell foam.

Closed-cell foam differs in that all of its tiny foam cells are closed and packed together. The advantages of closed-cell foam compared to open-cell foam include its strength, higher R-value, and its greater resistance to the leakage of air or water vapor. The disadvantage of the closed-cell foam is that it is denser, requires more material, and therefore, is more expensive. Even though it has a better R-value, typically the cost per inch is still higher than open-cell foam. The choice of foam can also be based on the requirements for the performance or application specific characteristics such as strength, vapor control, available space, etc. 

Open-cell SPF has an R-value around 3.5 per inch. Closed-cell SPF has an R-value of around 6.0 per inch (aged R-value).

Both types of foam are commonly used in most building applications and the choice for which to use can depend on many of the factors discussed above. Some foams are inappropriate in specific applications. For example, you typically would not use open-cell foam below grade or in flotation applications where it could absorb water; this would negate its thermal performance because water is a poor insulator compared to air. Closed-cell foam would be a good choice where small framing sizes need the greatest R-value per inch possible.

Polyurea coatings

We also offer the Polyurea as a coating to almost any surface. Some of our recent projects have included water tanks, taxidermy buildings, trailers, dumpsters and kennels for animals. You name it, we can probably coat it. Polyurea acts as a tough protective barrier over whatever you need to cover. It can save the life of metal equipment or protect concrete from receiving everyday damage you may have for it. 

Polyurea protective coatings are commonly used for the following reasons:

  • Abrasion Resistance 
  • Corrosion Protection
  • Waterproofing 
  • Chemical, Environment or Atmospheric Resistance 
  • Decoration 
  • Structural Enhancement

For decades, traditional materials such as paint, epoxy, fiberglass and vinyl esters have all been used to perform these various types of protective coating applications.

Polyurea coating technology is not new. In fact it has been around and in use for almost three decades now. Polyurea is newer and more advanced than these traditional coating systems and offers many advantages to the owner, specifier and contractor.

These advantages come mainly in the form of achievable physical properties, and its fast set, return to service characteristics. It can also be applied over a variety of different substrates (concrete, metals, wood and more) in a wide range of temperature and humidity environments. However, like all protective coatings, polyurea is no excuse not to perform proper surface preparation and quality control testing during application.

Polyurea’s major benefit is its fast set nature. It can typically return an area to service many times faster than traditional coatings, allowing the owner to put the facility back in use without days and weeks of revenue losing down-time. Down time for maintenance and coatings on water tanks, waste-water clarifiers, parking garages and chemical storage tanks costs the facility owner a great deal of money since these areas must be taken out of service while other coatings are applied and drying.

Most industrial use polyureas are spray applied, so it is fast to apply and accurately proportioned and mixed. This application style allows for virtually any mil thickness to be applied in one or multiple passes. Additional characteristics such as slip resistant additives and surface textures can also be incorporated, UV stable colors can be achieved, and even NSF potable water approved systems are also possible with polyurea.

Almost no coating can compare to polyurea when it comes to attainable physical properties. Polyureas can be formulated to achieve a tremendous range of properties from high elongation to superior tensile strength to hard or soft, all based on how the materials is formulated and correctly applied.
