❝Above and Beyond"

"Are there more stars I can give? These guys did a great job with our spray foam insulation. I kept asking for more areas and tougher places to work in. Not only that, but our job site wasn’t ideal. They had to do a lot of work moving and covering things for us. They went above and beyond for us. We also kept moving around the timeline. I’d say we were a nightmare customer, but they stuck with us and did great work. Pricing was reasonable as well. Thanks, guys! "

What is Spray Foam?

Also known as spray polyurethane foam (SPF), spray foam insulation is applied as a liquid that rapidly expands to form a continuous barrier against air and moisture. It’s ideal for sealing hard-to-reach spaces in attics, crawl spaces, and wall cavities, providing superior insulation and energy efficiency. Spray foam helps reduce drafts, allergens, and outside noise while lowering your energy bills.

Builders and property owners alike trust spray foam for its superior thermal performance and long-term durability.

Frequently Asked Questions

  • ▼ How long has Poly Seal LLC been installing spray foam insulation?
    Poly Seal LLC been installing spray foam insulation for 20 years.
  • ▼ Is Poly Seal LLC licensed, insured, and certified to apply spray foam?
    Yes, Poly Seal LLC is fully licensed, insured, and certified to apply spray foam through the SPFA (Spray Polyurethane Foam Alliance).
  • ▼ Does Poly Seal LLC specialize in residential, commercial, or both types of projects?
    Poly Seal LLC specializes in both residential and commercial spray foam insulation projects.
  • ▼ What type of spray foam do you recommend—open-cell or closed-cell—and why?
    The type of spray foam we recommend depends on the specific needs of the client. In our region, 2-pound closed-cell spray foam is the most common choice. It is primarily used on exterior walls and offers the highest R-value and air seal for your home. Open-cell spray foam works exceptionally well for sound deadening and is often applied over closed-cell spray foam in exterior attics and crawlspaces.
  • ▼ How much does spray foam insulation cost per square foot?
    Spray foam insulation typically costs around $1.20 per square foot per inch.
  • ▼ How do you calculate the total cost for my project?
    Poly Seal LLC calculates the total cost for your project by considering the total area that requires spray foam application, along with the desired thickness (in inches) of the spray foam.
  • ▼ Will spray foam improve comfort in bonus rooms or basements often found in Idaho houses?
    Yes, spray foam significantly improves comfort in bonus rooms and basements by minimizing air infiltration, allowing your HVAC system to heat and cool these areas more effectively.
  • ▼ How does spray foam hold up in Idaho’s agricultural or storage buildings where temperatures swing dramatically?
    This is one of the biggest benefits of spray foam. Spray foam insulation forms a hard surface, known as a skin, that prevents moisture and most chemicals from being absorbed into the product. This also helps to protect the metal surfaces underneath.
