Aluspõrandi

Aluspõrandi refers to the foundational layer of flooring in a building, serving as the structural base upon which the finished floor covering is installed. It is typically constructed from wood, concrete, or a combination of materials, depending on the building's design and purpose. The primary function of an aluspõrandi is to provide a stable and level surface, distributing the weight of the structure and its occupants evenly.

In wooden constructions, aluspõrandi is often made from planks or sheets of plywood or oriented strand board (OSB) laid over floor joists. This layer acts as a diaphragm, contributing to the overall rigidity of the floor structure and preventing excessive movement. It also serves as a substrate for various types of finishes, including hardwood, laminate, tile, or carpet. Proper installation is crucial to avoid squeaks and ensure the longevity of the finished floor.

Concrete aluspõrandi is common in residential and commercial buildings, especially those with slab-on-grade foundations or in multi-story structures. This type of aluspõrandi offers excellent durability and can be finished directly or serve as a base for other flooring materials. It provides a solid, monolithic surface that is resistant to moisture and pests.

The aluspõrandi can also incorporate insulation and vapor barriers to enhance thermal performance and prevent moisture issues. The specific materials and construction methods used for an aluspõrandi are determined by building codes, structural requirements, and the desired aesthetic and functional qualities of the final living or working space.
