Aluspõranda

Aluspõranda refers to the foundational layer of flooring in a building. It is the structural base upon which the visible floor covering, such as hardwood, laminate, tile, or carpet, is installed. The primary function of an aluspõranda is to provide a stable, level, and supportive surface for the finished floor.

The construction of an aluspõranda can vary depending on the type of building and its intended use. In many residential and commercial buildings, the aluspõranda is typically made of wooden planks or plywood sheets laid over floor joists. These joists are structural beams that span between walls or support beams, transferring the load of the floor to the rest of the building's structure. The aluspõranda planks or sheets are fastened securely to these joists.

In some cases, particularly in concrete slab construction, the concrete itself serves as the aluspõranda. In these scenarios, a vapor barrier and a leveling compound may be applied over the concrete before the final floor covering is installed.

The quality and integrity of the aluspõranda are crucial for the longevity and performance of the entire flooring system. A poorly constructed or damaged aluspõranda can lead to issues such as squeaking floors, uneven surfaces, cracks in tiles, or premature wear of other floor coverings. Therefore, ensuring the aluspõranda is sound and properly installed is a fundamental aspect of construction and renovation.
