Flooring Underlayment: Types, Benefits, and Installation

What is Flooring Underlayment?

Flooring underlayment is a thin layer of material installed on top of the subfloor before laying down your finished flooring. It comes in various materials, thicknesses, and densities, each offering unique benefits for different flooring types and applications. Think of it as a protective barrier and a supportive cushion for your beautiful new floors.

Benefits of Flooring Underlayment

Why is this often-forgotten layer so important? Here are some key benefits of using flooring underlayment:

  • Sound Insulation: Underlayment can significantly reduce noise transmission between floors, making your home quieter and more peaceful. Enjoy movie nights without worrying about noise complaints, thanks to the sound-dampening qualities of underlayment. This is especially beneficial in apartments, condos, or multi-story homes where noise can travel easily.  
  • Moisture Protection: Certain types of underlayment act as a moisture barrier, protecting your finished flooring from moisture damage caused by spills, humidity, or minor leaks. This is particularly important in areas like bathrooms, kitchens, or basements where moisture can be a concern.  
  • Thermal Insulation: Some underlayment materials provide thermal insulation, helping to regulate the temperature of your floors and improve energy efficiency. This can make your floors warmer in the winter and cooler in the summer, adding to your home’s overall comfort.
  • Cushioning and Support: Underlayment provides cushioning and support, making your floors more comfortable to walk on and reducing fatigue. This is especially beneficial if you have hardwood or tile floors, which can be hard on your feet and joints.  
  • Improved Comfort: Carpeting can provide unmatched softness and warmth, making it perfect for bedrooms and living rooms. The cushioning effect of underlayment enhances this comfort, creating a cozy and inviting atmosphere in your home.
  • Subfloor Imperfections: Underlayment can help smooth out minor imperfections in the subfloor, creating a more level surface for your finished flooring. This ensures a smoother and more even installation, preventing issues like unevenness or gaps between floorboards.  
  • Increased Longevity: By providing support and protection, underlayment can help extend the lifespan of your finished flooring. It acts as a buffer between the subfloor and the finished floor, reducing wear and tear and preventing damage from everyday use.

Choosing the Right Underlayment

With so many options available, how do you choose the right underlayment for your specific needs? Here are some key factors to consider:

  • Flooring Type: Different flooring types have different requirements. For example, hardwood flooring needs underlayment that allows for proper moisture ventilation. Certain types of laminate flooring, like those with a high-density fiberboard (HDF) core, are susceptible to moisture damage, so choosing an underlayment with a moisture barrier is crucial.
  • Sound Insulation Needs: If noise reduction is a priority, choose underlayment with high sound-dampening properties, such as cork or rubber. This is especially important in apartments or multi-story homes.
  • Moisture Concerns: If you’re installing flooring in a moisture-prone area, such as a bathroom or basement, choose underlayment with a moisture barrier. Cork and some types of foam underlayment offer good moisture protection. For laminate flooring, consider using a moisture barrier underlayment to protect the HDF core from moisture damage.
  • Subfloor Type: The type of subfloor you have can also influence your choice of underlayment. For example, concrete subfloors may require underlayment with moisture-resistant properties, while wood subfloors may benefit from underlayment that adds stability. If you’re installing flooring over a radiant heating system, choose an underlayment that is compatible with the system and won’t interfere with heat transfer.
  • Thickness: The thickness of the underlayment can affect the floor’s feel and performance. Thicker underlayment generally provides more cushioning and sound insulation, but it may also affect the height of the floor.
  • Budget: Underlayment costs vary depending on the material and thickness. Set a budget to help narrow down your options and choose an underlayment that fits your needs and your wallet. In Barrie, the cost of laminate flooring can range from $3 to $5 per square foot, so factor in the cost of underlayment when planning your project.

Sustainable Flooring Underlayment

With the growing trend of eco-friendly flooring options, it’s important to consider the sustainability of your underlayment choices as well. Look for underlayment materials made from recycled or renewable resources, such as cork or rubber. These options not only benefit the environment but can also contribute to a healthier indoor environment by reducing exposure to harmful chemicals.

Flooring Underlayment and Indoor Air Quality

The type of underlayment you choose can also impact the air quality in your home. Some underlayment materials may contain volatile organic compounds (VOCs), which can release harmful chemicals into the air. Choose low-VOC or VOC-free underlayment options to minimize your exposure to these chemicals and create a healthier indoor environment.

Installing Flooring Underlayment

Proper installation is crucial for maximizing the benefits of your underlayment. Here are some general guidelines:

  • Prepare the Subfloor: Ensure your subfloor is clean, level, and dry before installing underlayment. Remove any debris, dirt, or old flooring materials.  
  • Follow Manufacturer’s Instructions: Carefully follow the manufacturer’s instructions for installing the specific type of underlayment you’ve chosen. Different materials may have different installation requirements.
  • Overlap Seams: Overlap the seams of the underlayment to prevent gaps and ensure a continuous layer. This helps prevent moisture from seeping through and provides better sound insulation.  
  • Tape Seams: Use underlayment tape to secure the seams and prevent movement. This ensures the underlayment stays in place and provides a stable base for your finished flooring.
  • Use a Moisture Barrier: If necessary, install a moisture barrier over the subfloor before laying down the underlayment. This adds an extra layer of protection against moisture damage.

Conclusion

Flooring underlayment is an essential component of any flooring installation. By providing support, cushioning, sound insulation, and moisture protection, it can enhance the comfort, durability, and longevity of your floors. Choosing the right underlayment and installing it correctly can make a significant difference in the overall performance and enjoyment of your new flooring. If you’re planning a flooring project, don’t overlook this crucial layer. Invest in quality underlayment and enjoy the benefits for years to come.
