​Spray foam is the ideal, high-tech alternative to traditional insulation materials and roofing. At Green Peak Spray Foam, we specialize in high-quality foam roofing and spray foam insulation in Minnesota.

The reason why spray foam is considered the ideal insulation material is that it provides higher thermal resistance over other outdated techniques such as cellulose or fiberglass. It can also be sprayed into areas that are hard to reach with other types of insulation.

Spray foam insulation also works as an air sealant and thus helps in sealing off hundreds of crevices and cracks that conditioned air may otherwise escape through.

About Spray Foam

​Spray foam insulation is a spray-applied material that can form an air sealing and continuous insulation on roofs, contoured surfaces, walls, and around corners. It is formed using, mixing, and reacting unique chemicals at the job site to make a foam. These chemicals react quickly when combined, quickly expand on the surface to make a foam that seals gaps, insulated, and can create vapor and moisture barrier. Spray foam insulation is considered as the heat transfer-resistant and provides an efficient solution in lowering undesirable air infiltration through seams, joints, and cracks.

Spray Foam Insulation vs. Traditional Insulation

Traditional insulating products cannot work at the pace the spray foam does. Since spray foam locks the envelope of buildings, its R-value remains rigid. Whereas, the traditional insulating materials rarely achieve the claimed R-value due to the air escape in its applications.

Spray foam insulation can reach higher energy savings by insulating your home effectively. Due to its amazing properties, it pays for itself and doesn't settle or sag like traditional insulations. Hence, it's one application that is enough and doesn't need to remove or replace and is truly a green insulation material.

Applications of Spray Foam Insulation in Minnesota

​Spray foam is a diverse material in its properties and benefits that can be applied to diverse spaces. We are going to take a closer look at the number of substrates where spray foam can be insulated and what measures should be taken to maintain adequate adhesion and high performance of the insulation.
All of the substrates should be dry, clean, and free of oil, grease, rust, or loose scale before insulating spray foam. Another important consideration when insulating into the unknown, new substrate is to do a patch test first. Also, leave the spray to sit overnight and look for the proper adhesion the other day before starting the spray again. 

Fiberboard, gypsum board, wood

It is recommended that the highest moisture build of wood to be insulated with foam should be within 10%. Special measures need to be taken using laminates like plywood due to the availability of the moisture buildup, and the surface treatments can negatively influence the spray foam insulation. If the moisture buildup is suspected to be higher than 10-12%, it is good to perform an adhesion test.

Stainless Steel

The surface should be primed and clean with mineral spirits or xylol. In the majority of cases, it may be essential to sandblast to make a proper adhesion between stainless steel and primer.

Aluminum

Before spray foam insulation, the aluminum should only be cleaned using acid and never using a caustic solution. Moreover, the aluminum should be well primed before the application of spray foam insulation to eliminate the aluminum corrosion after the insulation by solvents created at the surface between aluminum and foam.

PVC and Plastics

To prepare the PVC surface, it is recommended to wash it with the mineral spirits. This particular plastic should be dealt with carefully, as some PVCs might contain a high amount of plasticizers that might result in adhesion loss due to the migration of plasticizer to the surface.

Bare Steel

After the cleaning of rust or bare scale, the spray foam can directly be insulated to bare steel. However, it is essential that the steel should be primed and sandblasted when insulating tanks.

Concrete

Concrete is the hardest to spray substrate because of the presence of high moisture buildup. Ensure that the moisture buildup is below 10%. To measure the moisture, you can use a moisture meter. However, if you find the excessive presence of salt on concrete, it is good to clean the concrete using muriatic acid.

Asphalt/Tar

When the spray foam is about to be sprayed on fresh tar or asphalt, it should be solvent-free. If the tar or asphalt is quite old, it can be used if it is solvent-free and properly cleaned, primed and sprayed.

Glass

The usual cleaning is needed for a glass before applying a spray foam insulation. If spray foam is simulated in an indoor window, a UV resistant layer is required to apply to the glass before insulating to eliminate degrading of the spray foam material by sun rays entering through the window.

Galvanized Steel

​Before priming the galvanized steel, the steel should be cleaned with an acid or solvent first then with water. Sometimes, these sheets might not be washed with acid, but it is possible to clean them with water and finally prime them for spray foam insulation.

Not every insulation contractor in Minnesota is familiar with the fact there is a need for cleaning and priming the surface before applying spray foam insulation. Ignoring this can leave the adverse effect on the surface resulting in air or heat loss. This is where we are most cautious, dealing with your spray foam insulation wisely as per the nature of the application surface. Be it home insulation or commercial spray foam insulation in Minnesota, Green Peak Spray Foam will do the job with the utmost professionalism.
