sisäkatot

Sisäkatot, or interior ceilings, are the upper surfaces of rooms in buildings. They serve both functional and aesthetic purposes, concealing structural elements like joists and wiring while contributing to the overall design of a space. Common materials for interior ceilings include plaster, drywall (gypsum board), wood, and metal tiles. The finish of a ceiling can vary greatly, from smooth, painted surfaces to textured finishes like popcorn ceilings or wood paneling. Acoustics are also an important consideration, with some ceiling materials designed to absorb sound and reduce echo. Lighting is often integrated into or suspended from the ceiling, playing a crucial role in illumination and ambiance. The height and design of an interior ceiling can significantly impact the perception of a room's size and openness. Modern construction often utilizes suspended ceilings, which are frameworks suspended below the structural slab, allowing for easy access to services and the incorporation of various lighting and ventilation systems. Specialty ceilings can also be found, such as coffered ceilings or vaulted ceilings, which add architectural interest and a sense of grandeur. Maintenance and cleaning of interior ceilings are typically straightforward, though older or textured finishes may require more specialized care.
