Nivellevy

Nivellevy is a Finnish term that translates to "leveling plate" or "leveling board." It refers to a type of construction material or component used to achieve a flat and level surface, particularly in flooring and subflooring applications. Nivellevy is designed to compensate for unevenness in the underlying structure, providing a stable and uniform base for subsequent finishes such as tiles, laminate, or parquet.

These plates are often made from materials like cement-bonded particleboard, gypsum fiberboard, or specialized wood composites. Their thickness and dimensions can vary depending on the specific application and the degree of leveling required. The installation process typically involves laying the nivellevy over the existing subfloor, securing it with screws or adhesive, and ensuring all pieces are tightly joined to create a continuous, smooth surface.

The use of nivellevy is common in renovations and new constructions where the original subfloor may have imperfections or where a high degree of flatness is necessary for the final floor covering. It helps prevent issues like cracked tiles or squeaky floorboards that can arise from an uneven base. In essence, nivellevy serves as an intermediary layer that enhances the quality and longevity of the finished floor.
