Flooring underlayment is a crucial layer placed between the subfloor and the finished flooring to improve the floor's performance and comfort. It provides benefits such as sound insulation, moisture protection, and enhanced durability. The right underlayment choice depends on the type of flooring and specific needs of the space.

Foam Underlayment

Commonly used for laminate, engineered wood, or vinyl flooring.

• Provides sound insulation, cushioning, and moisture protection.
• Lightweight and easy to install.
• Cost-effective.
• Not ideal for high-moisture areas unless specifically designed with a moisture barrier.

Felt Underlayment

Commonly used for carpet, hardwood, and laminate flooring.

• Provides cushioning, sound insulation, and enhances comfort underfoot.
• Reduces floor wear and offers some thermal insulation.
• Less effective in moisture control compared to other types.
• Best used in dry areas or in combination with a moisture barrier.

Radiant Heat Underlayment

Ideal for flooring installations requiring radiant heating, such as in bathrooms or living areas.

• Works with radiant heat systems to improve efficiency.
• Provides a comfortable, warm surface.

Moisture Barrier Underlayment

Essential for areas with high moisture levels, such as basements, bathrooms, and kitchens.

• Protects flooring from water damage by preventing moisture from reaching the subfloor.
• Crucial for areas prone to humidity or water exposure.
• Important to ensure compatibility with the type of flooring being installed.

Choosing the Right Underlayment

Selecting the appropriate underlayment is vital to the performance of your flooring.

• Helps with sound insulation, moisture protection, cushioning, and creating a smooth surface for the finished floor.
• Some underlayments also provide thermal insulation, making floors more comfortable in colder months.
• Certain underlayments are designed to work with radiant heat systems for added comfort.

Key Considerations

When selecting underlayment, consider the following:

• The type of flooring being installed.
• The moisture levels in the space.
• Whether sound insulation or thermal comfort is a priority.

The right underlayment ensures a long-lasting, comfortable, and well-installed floor.
