Top Common Questions About Spray Foam
Is Polyurethane Spray Foam Insulation Expensive?
Polyurethane Spray Foam is not cheap insulation. The initial installation cost is usually higher than standard fiberglass or blown-in insulation options. However, there’s no doubt it’s the best insulation investment decision you can make. Polyurethane Spray Foam represents a long-term investment in your property that will pay off over time. You will reap the rewards quicker than you imagine and it will also add significant value to your property. The immediate and long-term benefits of this type of insulation far outweigh the initial costs associated with it.
These benefits include:
- Lower Utility Bills, with energy saving costs up to 50%
- Reduced capacity requirements, maintenance, and wear and tear on HVAC equipment
- Improvement in indoor air quality because your property is better sealed from exterior pollution
- A more comfortable environment that helps preserve your family’s or employees’ health by not allowing airborne pollutants and allergens
- Superior soundproofing
- Added structural strength to your home/building
- The creation of a building envelope to protect your building (seals cracks and crevices)
- Protects your home/building from air and moisture infiltration
- Will not shrink, sag or decompose over the life of the building

- How much preparation is involved? This will depend on the type of application to be completed and wherein the building the spray foam needs to be placed.
What is the difference between Open-Cell Polyurethane Spray Foam and Closed-Cell Polyurethane Spray Foam?
For most residential & commercial applications, Polyurethane Spray Foam is categorized into two different categories: Closed-Cell and Open-Cell.
Closed-Cell Polyurethane Spray Foam
Closed-Cell polyurethane spray foam is the most common application. It’s considered a “closed” cell due to its high R-value (commonly around 6.7 per inch) – that is the material’s capacity to insulate and resist heat flow. The higher the R-value, the greater the insulation. Due to this high resistance, closed-cell spray foams can prevent water from seeping into the insulation, which creates moisture build-up. Moisture build-up will promote bacterial and mold growth, something you do not want inside your walls.
Open-Cell Polyurethane Spray Foam
Open-Cell Spray Foam Insulation provides superior energy efficiency and air infiltration control. It can be used in open wall cavities, crawl spaces, perimeter rim joists, cathedral ceilings, and garage ceilings. Open-cell R-value is usually 3.7-4.0 per inch applied.
Both Open-Cell and Closed-Cell Spray Foam Insulation are designed as a high-performance building envelope insulation system for both residential and commercial construction.
