Types of Insulation


  • Attic Insulation: Your attic is one of the best places to insulate, as it is one of the biggest culprits when it comes to home energy loss. Warm air rises, and if your attic isn’t insulated—or doesn’t have enough insulation—all that heat will escape right out, leaving your home a lot less comfortable in the winter. During the summer, an attic that isn’t insulated is much hotter, which makes the rest of your home a lot toastier as well!
  • Wall Insulation: Wall insulation helps provide not only decreased heating and cooling costs and a more comfortable home, but also superior soundproofing. If you’ve ever been in a home that doesn’t have wall insulation, you may have noticed how loud traffic and other outside noises seem!
  • Basement Insulation: The lowest level of your home offers a lot of potential for energy savings—but not if it isn’t well insulated! Even if your basement is unfinished and you don’t go down there a lot, don’t overlook it when it comes time to re-insulate.
  • Crawl Space Insulation: For a space so small, your crawl space can have a significant impact on your energy costs. If you don’t insulate your crawl space, your home can be subjected to all kinds of moisture problems and skyrocketing energy bills! Whether your house has a ventilated or unventilated crawl space, our insulation contractors can help.


  • Fiberglass Insulation: Fiberglass is one of the most popular and cost-effective types of insulation material; it is also one of the most effective products at stopping heat transfer and can be installed anywhere in your home, from basement ceilings to walls and around ductwork.
  • Cellulose Insulation: One of the most environmentally friendly insulation products, cellulose consists of mostly recycled materials. It’s similar to fiberglass insulation and provides good sound control and can work well in many areas of your home.
  • Spray Foam Insulation: Spray foam insulation is ideal for those small spaces, like the tiny cracks, gaps and crevices in your home’s envelope where air leaks in and out. When stopping air infiltration is critical, spray foam insulation is one of the best solutions!
  • Radiant Barrier InsulationRadiant barrier (or foil) insulation is ideal for attics where the sun’s rays can greatly impact the temperature. It works by helping reflect heat away from your home before it can penetrate the house.
