Thickness Of Laminate Underlay And Its Importance
Laminate flooring is a popular choice for homeowners due to its durability, affordability, and its ability to replicate the appearance of real hardwood flooring. However, it’s important to understand that the material used underneath the laminate flooring is equally crucial. The thickness of the laminate underlay plays a significant role in providing stability, reducing sound, and protecting against moisture.
-
Standard underlayment, typically 3mm thick, primarily offers sound reduction. However, it does not provide protection against moisture. This type of underlayment is suitable for areas that do not have high humidity or potential water exposure.
-
On the other hand, pre-installed underlayment requires an additional 3mm moisture barrier to safeguard the flooring from potential moisture damage. This is particularly important for spaces such as kitchens, bathrooms, or basements where moisture can be a concern.
-
For those seeking both sound reduction and moisture protection, the 3-in-1 underlayment is recommended. This type of underlayment is 2mm thick and provides dual benefits.
It is crucial to note that using a laminate flooring underlay thicker than 5mm is not recommended as it can cause issues with the flooring’s locking system, leading to installation and stability problems.
Different Types Of Underlayment For Laminate Flooring
Underlayment for laminate flooring is available in various materials, including foam, cork, and rubber. Each type of underlayment has its advantages and should be selected based on the specific needs of the flooring and the environment.
Foam underlayment is the most common type used and is typically made from polyethylene or polystyrene. It is known for its affordability, ease of installation, and sound reduction properties. Foam underlayment is available in different thicknesses, including the standard 3mm.
Cork underlayment is an eco-friendly option that offers excellent sound reduction and thermal insulation properties. It also provides a cushioned feel underfoot, making it a popular choice for those seeking extra comfort.
Rubber underlayment, often made from recycled materials, is highly durable and provides superior sound reduction. It is suitable for areas with high foot traffic or where soundproofing is a priority.
Considerations For Moisture Protection And Sound Reduction
Moisture protection is crucial when selecting underlayment for laminate flooring. Seeping moisture can damage the laminate planks and promote mold and mildew growth.
When using pre-installed underlayment, it is essential to add an extra 3mm moisture barrier for maximum protection. This additional layer acts as a shield against potential water or vapor penetration.
Sound reduction is another important factor in underlayment selection. Underlayment with soundproofing properties minimizes noise transmission between floors, creating a peaceful and quieter environment.
For optimal performance and longevity of the laminate flooring, it is recommended to choose underlayment that provides both moisture protection and sound reduction.
Avoiding Issues With The Locking System: Recommended Thickness
One of the key factors to consider when choosing the thickness of laminate underlay is to avoid any issues with the locking system. The locking system is what holds the laminate planks together, ensuring a secure and stable flooring surface.
Using underlayment thicker than 5mm can interfere with the proper engagement of the locking system, which may lead to installation difficulties and potentially compromise the integrity of the flooring.
Therefore, it is crucial to follow the manufacturer’s recommendations and guidelines for underlayment thickness to ensure a smooth and successful installation process.
- Choose underlay thickness according to manufacturer’s recommendations
- Avoid underlayment thicker than 5mm to prevent issues with the locking system
- Ensure proper engagement of the locking system for a secure and stable flooring surface
“Using underlayment thicker than 5mm can interfere with the proper engagement of the locking system.”
Proper Use Of Underlay For Extending Lifespan And Maintaining Stability
Using underlay for laminate flooring is highly recommended to extend the lifespan of the flooring and maintain its stability. Underlayment acts as a barrier between the subfloor and laminate planks, providing cushioning, support, and resistance against moisture and sound transmission.
- Underlay is essential for both 12mm and 8mm laminate flooring to enhance structural integrity and performance.
- It helps distribute weight evenly and reduces the risk of wear and tear, keeping the flooring in excellent condition for longer.
Underlayment rolls for laminate flooring are typically 0.9m wide and 9.1x30m long, allowing for convenient and efficient installation without the need for multiple seams.
Note: Carpet underlay is not suitable for laminate flooring. It is thicker and can interfere with the locking system, compromising stability and structural integrity. However, felt paper underlayment can be used, especially when installing over a concrete subfloor, as it provides moisture protection.
When laying laminate flooring over existing laminate, vinyl, concrete, tile, or plywood, it is crucial to ensure the existing surface is smooth, level, and uniform. Address and correct any bumps, imperfections, or unevenness before laying the new laminate for a seamless and stable finished floor.
understanding what goes under laminate flooring is crucial for a successful and long-lasting installation. The thickness of the laminate underlay, the type of underlayment selected, and considerations for moisture protection, sound reduction, and locking system compatibility play significant roles in enhancing the overall performance, stability, and lifespan of the laminate flooring.
