Choose the Best Underlayment for Laminate Flooring

What Is Underlayment?

Underlayment is a thin layer of material placed between the subfloor and laminate planks. It serves a variety of functions:

• Cushioning: Makes the floor more comfortable to walk on.

• Soundproofing: Reduces noise when walking on the laminate.

• Moisture Protection: Prevents moisture from the subfloor from seeping into the laminate planks.

• Levelling: Helps smooth out minor imperfections in the subfloor to ensure a flat, even installation.

Underlayment comes in different materials, each offering its own set of benefits depending on your specific installation needs.

Benefits of Using Underlayment for Laminate Flooring

Installing the right underlayment provides the following advantages:

• Soundproofing: Reduces footstep noise, especially important in multi-level homes and apartments.

• Moisture Protection: Acts as a barrier between the subfloor and the laminate, preventing water damage.

• Comfort Underfoot: Adds a cushioning layer that makes laminate flooring feel softer and more comfortable to walk on.

• Smooth Installation: Helps level out minor subfloor imperfections, making installation easier and ensuring a more durable floor.

Types of Underlayment for Laminate Flooring

There are various types of underlayment, each designed for different applications:

• Standard Foam Underlayment: A budget-friendly option for basic installations.

• Felt Underlayment: Offers a more premium feel and better sound absorption.

• Rubber Underlayment: Durable and excellent for soundproofing.

• Cork Underlayment: An eco-friendly option that provides good insulation and soundproofing.

• Combination Underlayment (with Moisture Barrier): Includes a built-in moisture barrier, ideal for areas prone to moisture.

Key Factors to Consider When Choosing Underlayment

Here’s what you need to consider before choosing the right underlayment for your laminate flooring:

• Subfloor Material: Concrete subfloors need moisture protection, while plywood subfloors can be more forgiving.

• Moisture Levels: If you’re installing laminate in a basement or a moisture-prone area, opt for underlayment with a built-in moisture barrier.

• Acoustic Needs: If soundproofing is important, look for materials like rubber or felt that absorb noise.

• Thermal Insulation: For rooms that tend to be colder, cork underlayment can provide insulation and warmth.

How to Install Underlayment for Laminate Flooring

Step-by-Step Installation Guide:

1. Prepare the Subfloor: Ensure the subfloor is clean, dry, and level.
2. Roll Out the Underlayment: Lay the underlayment flat across the subfloor, making sure the edges are aligned.
3. Seal the Seams: If you’re using underlayment with a moisture barrier, seal the seams with tape to prevent water penetration.
4. Cut and Trim: Trim excess underlayment around the edges of the room with a utility knife.
5. Install Laminate Flooring: Once the underlayment is secure, you can begin installing your laminate flooring planks.

While foam is the most affordable option, you’ll need to balance cost with your desired features, such as soundproofing or moisture protection.
