Can You Add Padding Under Hardwood Flooring?
Understanding the Benefits of Padding
Hardwood flooring is a classic and durable choice for homes, but it can have the drawback of transmitting sound vibration. Adding padding or an intervening layer under the hardwood can mitigate sound transmission and improve overall performance.
Types of Padding and Intermediate Layers
Soft, padded foam is often installed under laminate flooring, but it is not recommended for direct installation under solid hardwood. Instead, consider these options:
1. Red Rosin Paper or Builder’s Felt:
These materials minimize squeaking but do not absorb sound or soften the surface.
2. Solid Underlayment:
Soundeater, for example, is a free-floating underlayment designed for nail-down hardwood flooring. It does not need to be nailed to the subfloor but provides sound absorption.
3. Rubberized Membrane:
Proflex90 is a waterproof rubberized fabric sheet that offers limited sound control when used with hardwood floors. It is installed over the plywood underlayment.
4. Thick Underlayment with Intervening Plywood:
Thick underlayment can be installed over the subfloor, topped with a layer of plywood, and then the hardwood flooring. This provides both cushioning and sound absorption.
Alternative Sound Control Solutions
If replacing floors is not an option, consider these alternatives to padding:
1. Choose Denser Hardwoods:
Mahogany and Brazilian cherry are denser hardwoods that absorb sound better than softer hardwoods like oak or walnut.
2. Use Area Rugs and Runners:
Fabric rugs and runners dampen the sound of footsteps and protect hardwood surfaces from wear and tear.
3. Encourage Shoe Storage at the Door:
Removing shoes at the door reduces sound transmission within and between rooms, and keeps the home cleaner.
Installing Padding or Intermediate Layers
If you decide to add padding or an intermediate layer under your hardwood flooring, follow these steps:
- Remove existing flooring if necessary.
- Install the padding or intermediate layer according to the manufacturer’s instructions.
- Ensure the surface is level and free of debris.
- Install the hardwood flooring over the padding or intermediate layer.
- Nail or glue the hardwood flooring according to the manufacturer’s specifications.
Additional Tips for Reducing Sound in Hardwood Floors
- Caulk any gaps between the hardwood flooring and walls or baseboards.
- Use soundproofing curtains or drapes to absorb sound in rooms with hardwood floors.
- Install acoustic panels or tiles on walls or ceilings to further reduce noise levels.
By understanding the options available and following these tips, you can effectively reduce sound transmission in your hardwood floors and create a more peaceful and enjoyable living space.
