Urethane Spray Foam

Spray foam insulation was invented by a man named Otto Bayer in the 1940s. He began his work in Germany. The technology was brought to America by David Eynon in the 1940s. The spray foam we are familiar with today started to gain popularity around the 1980s. It has evolved into one of the best ways to insulate your home today!

How spray foam works:

Spray foam is comprised of isocyanate and polyol resin. When the two are mixed together, they create a chemical that expands 30 to 60 times its liquid volume when sprayed to a surface. This makes it valuable because it can mold to the shape of what it is being sprayed on. It is air tight which makes it a great insulator. It is great for walls, roofs, ceilings and attics.

Types of spray foam:

Open-Cell foam is soft with about ½ to ¾ of a pound per square inch. Closed-Cell foam has various degrees of hardness based on its density varying from 2 and 3 pounds per cubic foot. Closed-Cell foam has a thermal performance R-value of about 6.0 inch and Open-Cell has 3/6 inch R-Value. Open-Cell is not air tight so it is better suited for dry areas. Water is absorbed by Open-Cell foam. This makes it less valuable to Montana because of our extreme weather conditions. Closed-Cell foam is air tight and will not absorb water. It also enhances the structural stability of walls. The foam you would want to choose would be based on the conditions you are using it in. At Quality 1st Insulation we use Closed-Cell insulation due to the weather conditions in Montana. Closed-Cell is ideal for this area, keeping the heat out in the summer and holding it in during the long winter months.

Benefits of using spray foam:

Fiberglass insulation is made up of plastic and natural fibers and reinforced with fine glass fibers. It generally comes in batts, loose fill and blankets. At Quality 1st Insulation, we use fiberglass batts when customers choose to have an inexpensive option for insulation. Batts come in pre-cut squares and are best used on open spaces with limited obstructions. It’s usually used between studs, beams and joists.

Fiberglass is the least expensive way to insulate. Fiberglass batts usually come in a single variety. The only real difference between one roll and another is the overall color, thickness, and R-value.

If you’re not careful during insulation however, this can cause gaps and poorly insulated areas in your home or structure. When you have these unprotected areas in your home they can decrease your home or structures energy efficiency as much as 25%, along with other problems. If you choose to use this method, it is wise to have a professional do it to avoid any problems in the future. The initial cost of spray foam insulation may look like the more costly way to go when insulating. It’s true that the job will initially cost more to begin with, however in the bigger scheme of things, it will end up being the largest payback for your investment. When you choose to use spray foam, it increases the R-value of your home. When you increase your homes R-value, you’re creating a thermal barrier on your home. This reduces the amount of air that flows through your home. The higher the R-value in your home means the greater the insulation quality it has. So this essentially means more savings on your utility bills. If you choose to go with spray foam insulation, you’re making the area insulated air tight. This vastly reduces the amount of energy needed to keep your home at a comfortable temperature. Spray foam insulation also increases the strength of the area it is sprayed onto. This means fewer cracked walls from settling. It also strengthens your roof, making it more durable. All of these factors will save you money. You can see the savings add up in just a few short years, as well as for many years to come!

Quality 1st Insulation is the preferred choice when it comes to Spray Foam Insulation.

Spray foam insulation is not only air tight but it also forms an impermeable water barrier. This means it will protect against airborne moisture and leaks. More importantly, closed-cell spray foam insulation will not absorb any flood water. In the unfortunate event of a flood, the spray foam will isolate the water to the area the flood occurs. It also helps prevent mold, mildew and bacteria.

Spray foam insulation is designed to last for an indefinite lifespan. There is no need to maintain or update your insulation. This makes it eco-friendly by greatly reducing the amount of consumed materials. Also due to the reduction of energy needed to heat or cool your home you will be cutting your energy consumption. This is just another great reason to choose spray foam insulation!

Depending on the type of home you own and your insulation needs, spray foam can also provide additional benefits to those listed above. For example, crawl spaces can be hard to insulate with traditional batt applications. Spray foam insulation allows an opportunity to fully insulate these areas with ease.

At Quality 1st Insulation, we specialize in working with spray foam insulation and understand the many benefits this type of investment can provide to business and homeowners. Some of spray foam insulation benefits include:

• Better insulation from a medium that expands to be airtight and cures to prevent settling.
• Superior energy savings due to a higher R-value rating and airflow inhibition.
• Moisture resistance from a hydrophobic chemical composition.
• Mold deterrence thanks to its inert polymer materials.
• Exceptional lifespan that provides a better return on investment over the long term.
