Before and After
  • Spray Foam in Hoyleton,IL
    Before
    Spray Foam in Hoyleton,IL
    After

    A kneewall space is created when a finished room is built within a sloped roof. Often, these walls are “insulated” using fiberglass batting. Since fiberglass does not stop air flow, the insulation does next to nothing to air seal and insulate----causing rooms sharing walls with kneewalls to be very uncomfortable. Dr. Energy Saver St. Louis air sealed and insulated this Highland, IL homeowner’s knee wall with spray foam insulation. Now, inside air can’t get out of the house through the kneewall spaces and outside air can’t get in. This bedroom is comfortable again!

  • Spray foam in Troy,IL
    Before

    After

    The detail between the foundation wall, the sill plate, the rim joist, and the sub flooring allows for significant air leakage from the outside...especially when pipe wire penetrations are added. It is also this rim joist area that is often poorly insulated. Even when your rim joist is insulated with fiberglass bats, the outside air will still leak in through the bats, because this form of insulation acts as a filter. Spraying expanding foam insulation on the inside surface of the rim joist, to cover the sill plate down to the top of the basement wall, not only seals all air leaks very effectively, but it insulates as well.

  • Spray Foam Ductwork in Troy,IL

    After

    When ductwork or air handlers are located in an attic, they have to work much harder to keep your home comfortable. Battling temperatures upwards of 140 degrees F in the summer and as low as 30 degrees F or less in the winter, your attic air handlers need all the help they can get keeping your conditioned air the temperature you want it to be! One of the steps to achieving that is having your ductwork and air handlers sealed. Dr. Energy Saver encased this ductwork junction with spray foam insulation to seal any leaks, keeping that conditioned air traveling to where it needs to be---inside your living space!

Choosing the right spray foam for your home's needs

There are two major types of spray foam, each of which has different benefits for your home's energy efficiency.

  • Open cell foam: Open cell spray foam, which is also known as 1-part foam, is a common material that can be bought at hardware stores. This type of foam comes in small canisters and expands as it is applied to the surface to provide an airtight seal. Open cell foam is used for air sealing projects, which are typically followed by larger insulation installation methods.
  • Closed cell foam: Closed cell foam, or two-part foam, is the material that professionals use for large spray foam jobs. This foam consists of two chemical compounds that blend together at the application nozzle before they expand and harden on the treated surface. Closed cell foam offers excellent R-value and has the added benefit of providing air sealing and insulation in one step.

Advantages of choosing spray foam for your home

  • Provides air sealing as part of installation, eliminating leaks and drafts and raising the performance of the insulation.
  • Poly spray foam has a higher R-value per inch (6.2 or higher) than any other commonly used insulation.
  • Unlike other insulation, spray foam is waterproof and won't lose its insulating value in the event of a roof leak or other problem.
  • Spray foam is pest & mold-proof, so you don't have to worry about the insulation getting damaged over time.
