Spray Foam Insulation and Spray on Roofing

Spray Foam Insulation is better than any other type of insulation at reducing air leakage. ExpandoThane Spray on Roofing is better than any other type of Spray on Roofing at stopping water infiltration. Creating a building envelope keeps the outside elements outside and the inside elements inside


Whether its new construction or remodel, Minnesota Spray Foam Insulation is your right source for Spray Foam. Spray foam will keep the heat or cold out of the building.


Whether it's new construction or remodel we have the solution for you. There is more surface area in your walls than any other part of your home, meaning more area for air leakage.


Homes and structures without a slab floor can see tremendous amount of Heat Loss through their floor. Floors can also be cold to the feet as air passes through and around flooring.


Using Closed Cell in Metal Buildings provides many advantages, including but not limited to gluing the roofing to frame, adding additional racking strength to frame walls, reduce/eliminate air or water


Closed Cell is excellent at adding higher R-Value in thinner layers when compared to traditional insulation and open cell. No additional material is needed as the foam glues to the surface..

Sound Reduction

Open cell is excellent at absorbing sound, therefore reducing the sound transmissions through the walls.

Roof Coating

ExpandoThane is an excellent material for creating a seamless roof system. It expands 5 to 7 times it's original volume to seal off any and all screw holes, bug holes, etc.


Closed cell is an excellent source for insulating and strengthening any trailer that would be used for cooling, ie RV, Horse trailer w/ living quarters, refrigerant trailers, etc. It's also lightweight, only 2 lbs per cubic foot.

What Is Spray Foam Insulation?

Spray foam insulation in Minnesota Is one of the top-of-the-line insulations. Spray foam insulation is made from two chemicals that are in liquid form and combined on the job site. These two chemicals are isocyanate and poly resin. They are applied through a spray gun, and with special equipment, and are mixed as they are sprayed. The reaction that these two chemicals create allows them to expand 30 to 60 times its liquid volume. This happens as this spray foam is sprayed on the walls and between the boards. It comes out of the gun as a foam and then expands creating a quality seal that will prevent air infiltration, allergens, and dust from entering into your structures. There are actually Three types of spray foam insulation in Minnesota.

Open Cell

Open Cell foams are permeable to moisture and impermeable to air. R-Value ranges 3.6 to 4.0 per inch. Density is 0.5 lbs per cubic foot.Installed on wall and roof. Expands 150 times its original volume. Excellent at blocking air flow.

Closed Cell

Closed Cell foams stop air and moisture. R-Value ranges from 6.5 to 7.0 per inch. Density is 2.0 lbs per cubic foot.Installed inside wall of metal building. Expands 30 to 50 times its original volume. Excellent at blocking air & water infiltration.

Expando Thane

ExpandoThane is an expanding polyurea waterproofing material that expands 5 to 7 times its volume. It creates a seamless roof system.Installed on roof as a seamless roof system. Expands 5 to 7 times its original volume. Ultimate Water Proofing.

Is Spray Foam Insulation Worth It?

The initial installation and cost of spray foam insulation in MN is more than many other types of insulation. But is it worth the extra cost seems to be the question? It offers many benefits that other insulations do not offer. Spray foam lasts longer than any other insulation. The uniqueness that is offers all of its own, that comes in two chemical forms and with special equipment mixes and comes out of the spray gun as foam. It is filled with air bubbles or cells that expand onto your walls, creating a barrier that offers the full protection to your structure.

What are some benefits of Spray Foam Insulation?

Does Spray Foam Provide A Good R-Value?

The R-value of insulation is normally based on the ability of the insulation to reduce the amount of heat flow. The higher the R-Value of an insulation, the better your building is insulated. Spray foam insulation in Minnesota has one of the highest R-value of any insulation. The barrier that it forms also helps to block the heat flow so that it can not escape through cracks and crevices that do not normally get sealed closed by other forms of insulation. The closed cell spray foam can range in a value between 5 to 6.7 with a layer of insulation that is 1 inch thick. depending upon the manufacturer. The open cell has a lower R-Value factor and comes in with numbers that range around 3.7 for a layer of insulation of 1 inch thick. In comparison, fiberglass insulation that comes in batts, offers an R-Value of approximately 2.2 per inch.

(FAQ) Frequently Asked Questions

How much does Spray Foam Insulation cost compared to other insulation methods?

Spray Foam Insulation is considered to be more expensive than most conventional insulation however it cannot be compared to conventional insulation. When using the Spray Foam Insulation system it actually air seals the building and eliminates energy robbing air leakage and the associated problems with moisture mold and mildew and condensation problems inside the walls. When calculating the actual cost you need to consider the possible need to downsize HVAC systems, eliminate building wraps and eliminate a significant portion of the material and labor costs associated with an air-sealing approach.

How Long Does Spray Foam Last? Does It Change Physically?

Aging is not an issue with Spray Foam. It is inert, and its physical and insulating properties are constant.

What is the difference between open-cell and closed-cell foams?

Both open-cell and closed-cell foams stop the movement of air and slow down the transfer of heat. Closed-cell foams, on the other hand, have low vapor permeance due to their cell structure. These foams, depending on thickness, may be considered a vapor retarder but not a vapor barrier. In climate zones 6-8 a vapor retarder system may be required on the warm side of the insulation relative to the design of the wall or ceiling system. Closed-cell foams also have a high compressive strength which allows them to be used for exterior applications. Open-cell foam should never be used for exterior applications. Open-cell foams are more cost effective per unit of R-value than closed-cell foams but do not provide the structural contribution to a building that closed-cell foams do.

What Is Spray Foam Insulation Made Of?

Spray Foam is an organic material developed from products of the petrochemical industry. It is a two component system that is sprayed like paint. The chemical constituents are similar to those used in the manufacturer of many products already in your home, such as upholstery foam and the foam used for pillows and mattresses---although the properties of the foam are different. Spray Foam is an environmentally friendly urethane in which the ozone-robbing CFC's have been replaced with air and water.

Does Spray Foam Insulation Have Building Code Approvals?

Yes! Foam has approval of all four major building codes in the United States and the Canadian building code. In fact, it is one of the most extensively tested insulation products ever. Concern in the 1970's over the excessive off-gassing of an early foam product called urea formaldehyde, and related concerns in subsequent years over the health effects of other insulating products, specifically asbestos and fiberglass, have resulted in some of the most thorough and sensitive emissions testing of a new building product to date. Based upon the results of this stringent testing, Spray Foam met the requirements of the building codes and subsequent re-certifications as required on a periodic basis.
