Buying Guide for the Best Laminate Underlayments

Choosing the right laminate underlayment is crucial for ensuring the longevity and performance of your laminate flooring. Underlayment provides a smooth surface for the laminate to rest on, helps with sound absorption, and can offer moisture protection. When selecting an underlayment, consider the specific needs of your space, such as the type of subfloor, the level of moisture, and the amount of foot traffic. Understanding the key specifications will help you make an informed decision that best suits your requirements.
ThicknessThickness refers to how thick the underlayment material is. This is important because thicker underlayments can provide better sound insulation and cushioning underfoot. Underlayments typically range from 2mm to 6mm in thickness. For areas with high foot traffic or where extra comfort is desired, a thicker underlayment (4mm-6mm) is recommended. For standard residential use, a 2mm-3mm underlayment is usually sufficient. Consider your comfort needs and the level of sound insulation you require when choosing the thickness.
MaterialThe material of the underlayment can affect its performance in terms of sound absorption, moisture resistance, and durability. Common materials include foam, cork, and rubber. Foam is lightweight and provides basic cushioning and sound reduction, making it suitable for most residential applications. Cork offers superior sound insulation and is naturally resistant to mold and mildew, ideal for areas where moisture might be a concern. Rubber is highly durable and provides excellent sound insulation, making it suitable for high-traffic areas. Choose the material based on the specific needs of your space, such as moisture levels and desired sound insulation.
Moisture BarrierA moisture barrier is a layer within the underlayment that prevents moisture from seeping up from the subfloor into the laminate flooring. This is particularly important in areas prone to moisture, such as basements or bathrooms. Some underlayments come with an integrated moisture barrier, while others may require a separate moisture barrier to be installed. If you are installing laminate flooring in a moisture-prone area, look for underlayments with a built-in moisture barrier to protect your flooring from damage.
Sound InsulationSound insulation refers to the underlayment's ability to reduce noise transmission between floors. This is important in multi-story buildings or apartments where noise can be a concern. Underlayments with higher sound insulation ratings can significantly reduce the noise of footsteps and other impacts. Look for underlayments that are specifically designed for sound insulation if noise reduction is a priority for you. These products often have ratings such as IIC (Impact Insulation Class) and STC (Sound Transmission Class) that indicate their effectiveness.
Compatibility with Flooring TypeNot all underlayments are compatible with all types of laminate flooring. Some laminate floors have specific requirements for underlayment to ensure proper installation and performance. Always check the manufacturer's recommendations for both the laminate flooring and the underlayment to ensure compatibility. This will help prevent issues such as improper fitting, reduced durability, or voiding of warranties. Make sure to choose an underlayment that is designed to work with your specific type of laminate flooring.
