laattoja

Laattoja is the Finnish plural form of laatta, meaning tile. In architecture and interior design, tiles are flat, rigid pieces used to cover floors, walls and other surfaces. They are designed to be bonded to a substrate and often glazed or textured for appearance, durability and water resistance. The term covers a wide range of materials and styles and is widely used in homes, commercial spaces and public buildings.

Common materials include ceramic tiles (made from clay and minerals), porcelain tiles (dense, low porosity ceramic), natural stone tiles (such as marble, granite and slate), glass tiles, and concrete or terrazzo tiles. Ceramic and porcelain tiles are often glazed on the surface, while some are unglazed for slip resistance or a natural finish.

Manufacture involves preparing the raw materials, forming the tile (pressing or extrusion), drying, and firing in a kiln. Glazes or surface treatments are applied before or after firing. Tiles are produced in a variety of thicknesses, sizes and edge profiles, including rectified edges for precise joints.

Uses and installation: Tiles are widely used for indoor flooring, walls (including bathrooms and kitchens), backsplashes, and outdoor surfaces in frost-resistant varieties. Installation requires a stable substrate, appropriate adhesives, grouts, and expansion joints to accommodate movement and prevent cracking.

Care and durability: Tile surfaces can be resistant to staining and moisture when properly glazed and sealed. Durability depends on material, underfoot usage, and maintenance. Common considerations include slip resistance, water absorption, and impact resistance, as well as compatibility with underfloor heating.
