A frequently asked question when it comes to laminate flooring is whether or not you will need underlayment next time you're starting a project. Knowing what this means and how underlayment benefits you or just the requirements for laminate flooring can help guide you along. This article discusses laminate underlay and its need for laminated plywood for all types, before going into the laminated floating flooring installation considerations.

What is Underlayment?

Underlayment is a thin layer of material, typically plastic or synthetic substance, used to install different types of flooring, including laminated plywood. It has a number of uses, including:

Floor to Floor Sound Absorption

Sub-Floor Moisture Barrier: Keeping the moisture from seeping up into your flooring.

Cushioning: Providing a soft spot to land that will also take some of the pressure away.

Leveled: Provides a smooth surface over minor inequities in the subfloor.

Types of Underlayment

Different types of underlayment are available for different flooring needs:

Foam Underlayment: Lightweight and simple to install, this type of underlayment provides minor noise insulation and cushioning. The installation is appropriate for most laminate flooring over laminated plywood.

Felt Underlayment: Made of recycled fibers, felt underlayment is usually used for its excellent noise-dampening capabilities and helps control moisture, making it suitable for laminate flooring in moisture-heavy rooms.

Rubber Underlayment: One of the toughest and heaviest underlays available, rubber is best known for its excellent sound insulation capabilities as well as unique cushioning. It is ideal for high-traffic areas and multi-story homes.

Cork Underlayment: A great soundproofing material, cork is also eco-friendly and resistant to mold/mildew, making it a top choice for sustainable products.

Should You Use Underlayment for Laminated Plywood Flooring?

Considerations:

Quality of Laminated Plywood: If a laminated plywood layer is in really good shape – flat, smooth, and dry – you might wonder why additional underlayment is necessary. However, even the best plywood can benefit from the extra cushioning and moisture protection that underlayment offers.

Laminate Installation Type: When installing laminate flooring on a floating floor, you won't typically use any underlayment. The floor must be able to expand and contract without causing damage.

Advantages of Underlayment

Comfort: Laminate flooring underlay provides a softer and more tactile cushioning beneath your feet, making it more comfortable to walk on.

Noise Control: Using underlayment reduces noise by creating different layers, making your space more comfortable with less sound transmission.

Moisture Barrier: Underlayment functions as a moisture barrier between the laminate floor and laminated plywood subfloor, which could otherwise damage the laminate.

Once installed, underlayment improves longevity by absorbing impact and wear.

Provides Better Insulation: This aids thermal insulation of your home, making it more energy-efficient by saving on heating and cooling costs.

How To Install A Laminate Floor Over OSB Subfloor

Step 1: Prepare the Subfloor

Ensure your laminated plywood subfloor is clean, dry, and even. Repair any damages and clean up debris that might obstruct installation.

Step 2: Select The Best Underlayment For Your Needs

Choose the right underlayment for your needs. A thin layer of foam underlayment is most common for residential flooring, but felt or rubber pads are the best options in moisture-prone locations.

Step 3: Set Up the Underlayment

Install the underlayment by unrolling it across the entire laminated plywood floor, allowing it to fit wall to wall.

Overlap Seams: If multiple sheets are necessary, overlap them a few inches and tape them down to prevent sliding.

Trim Excess: Trim any excess underlayment at the edges with a utility knife.

Step 4: Lay the Laminate Flooring

After laying down the underlayment, install the laminate following the manufacturer's directions for your specific flooring. This usually consists of clicking the planks together or using adhesives based on the type of flooring.

Step 5: Finishing Touches

Install baseboards or trim to hide the expansion gaps around the perimeter after you have installed the laminate flooring. This will complete the floor and help prevent peeling or tearing.

Conclusion

So, the answer to whether or not laminate on laminated plywood without underlayment is  yes. Not only does the underlayment provide softness, extra insulation, and sound absorption, but it is also essential in blocking out moisture to prolong your floor's durability. Investing in underlayment is a great way to gain peace of mind and ensure that your floors are installed correctly, allowing you to enjoy your laminate flooring for years.

Always make decisions based on specific space requirements and consult with laminated plywood manufacturer guidelines while planning your laminate flooring project. This will reward you with a beautiful, durable, and comfortable laminate floor for many years.
