10 Best Laminate Underlayments 2025 in the UK

The Acoustic Sonic Gold Underlay offers a robust 5mm thickness, which is ideal for providing a substantial base under wood and laminate flooring. Its thickness contributes to impressive sound absorption, reducing noise by 24dB, making it suitable for areas where sound insulation is crucial. Additionally, the underlay is designed with a gold foil moisture membrane barrier, offering effective protection against dampness; this is a significant advantage in preventing damage to flooring from moisture.

The material used combines both sound and heat insulation benefits, adding comfort and energy efficiency to the home environment. With a coverage of 15 square meters per roll, it caters to moderately sized areas, and the ability to choose different sizes provides flexibility for varying needs. However, users should be aware that joining seams require Barrier Pro X Tape, an additional step in installation that may incur extra costs and effort.

The underlay performs well in compatibility across all wood and laminate flooring types, ensuring versatility for most installations. Though it doesn't rank highly among musical instruments and acoustic treatments, it has gained positive reviews with a 4.5-star rating from users praising its insulation qualities. Weighing 3 kg per roll, it is manageable for installation. For individuals looking to enhance sound and heat insulation while maintaining moisture protection under laminate or wood flooring, this underlay is a good option. Some may find the installation process slightly cumbersome, but the benefits of sound and moisture protection outweigh this minor drawback.

The 3mm Acoustic Silver Underlay by Royale is designed for wood and laminate flooring, offering a decent thickness that helps level minor floor imperfections. Its standout feature is the silver foil waterproof membrane, which acts as a moisture barrier to protect floors from dampness—a key factor for maintaining the longevity of laminate or wood floors. This underlay also provides good sound insulation, which can significantly reduce noise, making it a smart choice if you want a quieter room.

The material and design cater well to residential use, and it comes in a convenient 15m² roll for easy coverage. To maintain the warranty, you need to use Barrier Pro X Tape to join seams properly, adding a small installation step. The product has strong customer ratings, indicating reliability and satisfaction.

This underlay fits well for homeowners looking to improve floor comfort, moisture protection, and sound reduction without complex installation. If you’re seeking heavy-duty moisture protection or very thick cushioning, this might not be the best fit, but for typical wood or laminate flooring setups, it strikes a good balance between performance and ease of use.

The Royale 2mm White Foam Underlay is designed for use under laminate and real wood floors. Its 2mm thickness is on the thinner side, making it suitable for installations where height clearance is limited but offering less cushioning and sound absorption compared to thicker options. Made from foam, it provides basic comfort and some level of sound insulation, helping reduce floor noise, though it may not deliver strong acoustic performance.

The product does not explicitly mention a moisture barrier, so it may not offer significant protection against dampness from below, which is a consideration if installing over concrete or in moisture-prone areas. It is compatible with most laminate and hardwood floors, making it a versatile choice for general residential use. The roll size covers 15 square meters, convenient for medium-sized rooms.

Customer feedback is positive, with high ratings reflecting satisfaction with its performance for typical floor installations. For those seeking a straightforward, budget-friendly underlay to improve comfort and reduce minor noise under laminate or wood flooring, this Royale foam underlay is a fitting option. However, if moisture protection or superior sound insulation is a priority, thicker or specialized underlays with built-in barriers might be more suitable.
