What Is Floor Insulation?


Duct Insulation Services in Denver, CO

Floor insulation refers to the process of insulating the floor structure in a building to improve energy efficiency, thermal comfort, and soundproofing. It involves adding insulation material to the floor space, typically between the floor joists or beneath the floorboards, depending on the construction type. Floor insulation helps prevent heat loss through the floor, especially in buildings with suspended or raised floors. It creates a thermal barrier that reduces heat transfer between the interior and exterior of the building, keeping the indoor space warmer in cold weather and cooler in hot weather.

Do Floors Really Need Insulation?


While not all floors may require insulation, it is beneficial in many situations, especially for suspended or raised floors, floors above unconditioned spaces like crawlspaces, or floors in contact with the ground. Consulting with insulation professionals like NetZero Insulation in Denver, CO, can provide guidance on whether floor insulation is necessary for your specific situation.

Floor Insulation for All Types of Rooms


At NetZero Insulation, we have the expertise to determine the most suitable floor insulation option based on the specific requirements and challenges of each area in your home. We offer the following types of floor insulation:

  • Floor Above Garage – We utilize blown-in insulation for living spaces above garages to fill the gap between floor joists. When the garage ceiling is finished with gypsum board, dense-pack cellulose is often the ideal solution.
  • Floor Above Basement – Our primary focus here is to air-seal and insulate the rim joist. This can be accomplished using 2-part spray foam or a combination of rigid foam insulation and spray foam. In some cases, rigid foam wall insulation may also be recommended.
  • Basement Floor – To avoid potential mold and moisture damage issues, we advise against using wood subflooring for insulating basement floors. Instead, we recommend ThermalDry® Insulated Floor Decking™, a specialized subflooring made from waterproof rigid foam and composite board. This not only provides thermal insulation but also serves as a sturdy base for finished flooring.
  • Floor Above Crawl Space – If you’re experiencing cold floors above a crawl space, we highly recommend insulating the crawl space itself. This involves sealing the rim joist, insulating the crawl space walls and floor, and installing rigid foam wall insulation in colder regions.
  • Floor Above Cantilever – Cantilevered floor areas created by upper-floor overhangs often require insulation improvements. By temporarily removing the soffit material covering the underside of the cantilever, we gain access to the joist bays for sealing and insulation.

How Long Does Floor Insulation Take?


In general, the installation process for floor insulation can be completed within a few days to a week. However, it’s important to note that this is just an estimate, and actual timelines may vary. Factors such as the accessibility of the area, any necessary preparations or repairs, and the availability of materials and labor can influence the overall installation time. To get a more accurate timeline for your specific floor insulation project, it’s best to consult with a professional insulation contractor.
