Types of Insulation

What kind of insulation do you need for your retrofit (re-insulation) or new construction project in the Chicago, Illinois area? ThermaSeal / Lakeside Insulation has experience insulating both homes and commercial buildings.

What Is Insulation & How Does it Work?

Insulation is a material that stops the transfer of heat to help keep your home more comfortable all year round—warmer in the winter and cooler in the summer. It can be installed in various areas of your home, including:

Different types of insulation work a bit differently, but in general, how well a type of insulation stops heat transfer is measured as an R-value. A particular type of insulation’s R-value refers to its resistance to heat flow, and the higher the R-value, the more effective the type of insulation is at stopping heat transfer. The type you install depends on a number of different things, including:

  • Where you live
  • How old your home is
  • The type of HVAC equipment you have
  • And more

The Different Types of Insulation

There are a few different types of insulation, and ThermaSeal / Lakeside Insulation installs:

  • Fiberglass. Fiberglass, which has been used to insulate homes for decades, is available as loose-fill or batts. Fiberglass is made of tiny glass fibers and is often installed in attics but can be used to insulate walls and crawl spaces as well. It is often pink in color.
  • Cellulose. Cellulose insulation is environmentally friendly—it consists of up to 85 percent recycled material and takes less energy to make than other insulation materials—and can be installed in any area of a home.
  • Spray foam. Typically made of polyurethane, spray foam is applied wet and expands into thick foam. Spray foam insulation can be installed in crevices and hard-to-reach areas and can help reduce air infiltration.
