Get the absolute best Spray polyurethane foam (SPF) insulation for Your Home

Whether you’re in Round Lake, Libertyville, or anywhere in Lake County, IL, spray foam insulation can significantly enhance the comfort of your home while minimizing energy loss.


Spray foam insulation reduces energy costs and lowers utility bills by forming an airtight seal that stops air movement. According to the U.S. Department of Energy, up to 40% of a home's energy is lost due to air infiltration through drafts around wall sockets, windows, and doors. Spray foam expands to fill every small hole and crevice, creating a superior air seal and delivering an exceptional R-value per inch of installed foam. Trust FDI Insulation to make your home more energy-efficient and comfortable year-round.

Closed Cell Vs. Open Cell Foam

Benefits of Closed Cell Foam
Because it provides double the R-value of open cell foam in a typical wall cavity, closed cell foam is a great option for high-performance insulation, particularly in spaces with limited space. Its rigidity improves the building's structural stability, and it comes in E84 fire-rated forms. Closed cell foam is a dependable and long-lasting insulation choice since it also serves as a vapor barrier, successfully keeping moisture and water out of the house. The foam is also impervious to water damage.

Benefits of Open Cell Foam:
Open cell foam is ideal for insulating difficult-to-reach places in a house because of its capacity to greatly expand after application. One of its greatest benefits is its versatility, which allows it to cover difficult areas that closed cell foam could find more difficult to access. Open cell foam effectively fills the spaces between studs when it is sprayed, offering superior soundproofing. Open cell foam is more suitable for areas with milder climates since it is less good at insulating against high temperatures, although being less expensive than closed cell foam.

Spray Foam Insulation FAQ's

Hi there! Have some questions about our company? Find the answers below. 

  • How much does spray foam insulation cost, and is it worth the investment?

    The cost of spray foam insulation depends on several factors, including the size of the area being insulated, the type of spray foam used (open cell or closed cell), and the complexity of the installation. On average, spray foam tends to be more expensive upfront compared to traditional insulation. However, it provides significant long-term savings on energy bills by creating an airtight seal that greatly reduces energy loss. Over time, homeowners often find the investment worthwhile, as spray foam can lower heating and cooling costs, increase the home's energy efficiency, and improve overall comfort. For a personalized estimate, FDI Insulation can assess your property and discuss the best insulation options for your needs.

  • Can spray foam insulation help reduce noise?

    Yes, spray foam insulation can provide soundproofing benefits. While closed cell foam is better for thermal insulation, open cell foam is particularly effective at reducing noise transmission between rooms or from outside. It’s a great choice for creating a quieter home environment.


  • How long does spray foam insulation last?

    Spray foam insulation is extremely durable and can last 20 to 30 years or even the entire lifetime of your home when properly installed. Unlike some traditional insulation materials, it won’t sag or degrade over time, providing consistent performance and long-term energy savings.

  • Can I install spray foam insulation myself, or should I hire a professional spray foam contractor?

    While it might be tempting to try a DIY spray foam installation, it is generally not recommended. Spray foam insulation requires specialized equipment and precise application techniques to ensure it performs correctly and safely. Improper installation can result in gaps, poor insulation coverage, and even potential safety hazards, such as improper curing or off-gassing. Hiring a professional spray foam contractor ensures that the job is done right, maximizing energy efficiency and providing peace of mind. At FDI Insulation, our experienced team uses the best practices to deliver reliable and long-lasting results.

  • What is spray foam insulation, and how does it work?

    Spray foam insulation is a type of insulation that expands upon application, creating an airtight seal in your home. It is sprayed as a liquid that quickly expands to fill gaps, cracks, and crevices, preventing air and moisture from infiltrating your home and providing superior thermal performance.
