Insulated basement subfloor system

See what makes this insulated subfloor a smarter solution for preparing your basement floors for finishing.

When finishing or remodeling your basement, the choice of flooring will be one of the most important decisions you make.

No matter what type of finished flooring you choose, it’s important to install a basement subfloor that provides insulation value, along with resistance to mold and moisture damage. These qualities are critical because of basement conditions: moisture from the slab (or from other sources, like water leakage) that can lead to mold and wood rot, and heat loss through the slab that can make your finished floor uncomfortably cold.

ThermalDry® Insulated Floor Decking™, installed by Northland Basement Systems, offers many advantages over traditional plywood subflooring.

Advantages of ThermalDry® Insulated Floor Decking™

  • No damage from mold or moisture. ThermalDry® Floor Decking contains no organic, moisture-absorbing material, so it won’t attract mold or be damaged by moisture.
  • More basement headroom. Thanks to ThermalDry®’s low profile, you save a full inch of ceiling height compared to a built-up wood subfloor.
  • Cold protection. ThermalDry® decking has a continuous layer of rigid foam insulation to ensure that your finished floor surface will be warm & comfortable.
  • Versatility. Use ThermalDry® decking as a subfloor treatment beneath all types of finished flooring.
  • Quick installation. Decking panels interlock with tongue-and-groove joints, and don’t require fasteners.

Basement flooring done right. Finished flooring can easily be installed on top of your ThermalDry® insulated subfloor without the worry of moisture or mold ruining your new basement floors.

Avoid problems of installing flooring over concrete basement floors

For many years, contractors have struggled to find suitable basement subflooring. A plywood subfloor (installed on the concrete slab or on wood sleepers) will work well until the wood absorbs enough moisture to attract mold; then the floor will have to be torn out. Wouldn’t it be better to avoid this messy and expensive replacement?

By eliminating wood and combining insulation with moisture-proof underlayment, ThermalDry® Decking has all the qualities that other basement subfloor treatments lack.

In addition to offering a smarter basement subfloor alternative, we also offer finished flooring products designed specifically for basements. MillCreek wood flooring is the ideal finished flooring solution to install over your warm, dry insulated subfloor. Padded carpet can also be installed by your local floor covering expert.
