The 3 mm underlays feature a built-in self-adhesive tape, which simplifies the installation process and eliminates the need for additional adhesives or tapes. This convenient feature saves time and effort during the installation of the underlay. The self-adhesive tape ensures a secure and tight bond between the underlay and the floor panels or subfloor. This bond prevents any movement or shifting of the underlay over time, maintaining its effectiveness in insulation, leveling, and noise reduction. Moreover, the inclusion of a damp-proof membrane in the underlay helps to protect against moisture penetration, contributing to the prevention of mold fungi development. This barrier provides added protection for the subfloor and the overall indoor environment. The 3 mm underlays are known for their high density and high-quality construction, ensuring durability and longevity. They are designed to level out surface irregularities with their flexible backing, creating a smooth and even foundation for the flooring. These underlays have also received technical and hygienic certifications, further affirming their quality and suitability for use in construction and public utility buildings. Lastly, it is worth noting that the 3 mm underlays are 100% recyclable, making them an environmentally friendly choice for flooring insulation and improvement of acoustic comfort.
