• ▼ 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.

  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.
