Types of Insulation

  • Spray Foam

    A insulating foam plastic spray which applies as a liquid and then expands to make an air-tight seal.

  • Cellulose

    Since Cellulose Insulation is created from a mixture of recycled paper products and binding agents to bring it together, cellulose is considered a “green” product. Cellulose insulation has been used for decades to insulate homes for warmth.

Important Areas of Insulation

  • Walls

    Walls make up a lot of the house’s surface area, so it’s not too surprising that a house’s largest heat sink tend to be the walls.

  • Garage

    By insulating your garage you will be protecting your pipes from freezing in winter.

  • Attic

    The fact that “heat rises” makes your attic one of the most important rooms to insulate in your home.

  • Crawl Space

    Not only is crawl space insulation important to keep you warm, but it is also important to keep your pipes from freezing.

  • Basement

    With the proper insulation not only can you keep out the cold, but also many insulation types can keep out pests such as mice, insects, as well as being mold resistant.
