The Best Spray Foam Installers West of the Mississippi
Spray foam insulation is a high-quality form of residential and commercial insulation that combines the chemicals isocyanate and polyol resin. When these chemicals combine, they expand and form a dense, damage-resistant material that is ideal for insulating your property. We offer two types of spray foam material, which are open-cell spray foam and closed-cell spray foam. Both are reliable solutions but with notable differences. Below is a closer explanation of each option to help you decide which may be best for you.
On the other hand, closed-cell spray foam is far superior to all other options in just about every category. It has a much greater R-value (almost double the R-value per inch in many cases. This means it helps prevent temperature fluctuations inside your property, ensures the best possible comfort and air quality, and greatly reduces the risk of water and moisture damage. The initial cost of closed-cell spray foam is higher. However, much of the cost has return value as property owners often receive reductions in their heating and cooling costs by 15% or more. Closed-cell spray foam lasts for more than 75 years in many cases, which is much longer than all other insulation material options.

Why Choose Spray Foam Insulation for Your Home or Commercial Property
Spray foam insulation offers numerous unique benefits that other insulation solutions such as fiberglass and cellulose simply cannot provide to the same extent. The advantages spray foam offers most notably include an increase in your property’s energy efficiency, improvements in the air quality, the ability to keep pests away, and a reduced risk of water and moisture damage. Spray foam is also far more durable and long-lasting as well.
Spray Foam Insulation vs. Fiberglass Insulation
Fiberglass is a reliable insulation material that is made by turning recycled glass into fibers, which is then used as an insulation material. Although fiberglass insulation is reliable, spray foam insulation is far superior to fiberglass in terms of quality. This is simply because the R-value is much higher. Additionally, fiberglass usually only lasts for approximately 20 to 30 years before it must be replaced, which is on average less than half the lifespan of spray foam.
Spray Foam Insulation vs. Cellulose Insulation
Cellulose offers similar quality as fiberglass insulation. It is made of recycled paper (i.e. newspaper), and it is a cost-effective solution. However, for home and business owners that seek the highest-quality insulation material possible, spray foam is the way to go. With that said, cellulose insulation is usually considered superior to fiberglass, and it offers slightly higher R-value and durability on average.

When to Replace Your Existing Insulation With Spray Foam Insulation
Many home and business owners are unaware of the need for new insulation, and many of our clients are pleasantly surprised at the full extent of benefits spray foam offers. We recommend inspections of your property’s insulation every two to three years or annually if your insulation is older and at a greater risk of damage. There are also certain signs that indicate a need to replace your existing insulation. These signs include:
- Drafts inside your property
- High energy costs
- A decline in comfort and air quality
- Pest infestation
- Signs of condensation
In terms of whether spray foam or another material option is right for you, we can assist you with making those decisions. We recommend spray foam due to its unmatched quality, but we also understand that different clients have different needs, goals, and budgets. That is why we provide reliable fiberglass insulation and cellulose insulation services as well.
