Kattematerjali

Kattematerjali, or covering materials, refers to materials applied to surfaces to protect, insulate, and finish them aesthetically. The term covers both exterior and interior applications, including walls, roofs, and ceilings, and encompasses boards, panels, tiles, bricks, stones, coatings such as paint, and composite systems used as finishing layers.

Exterior kattemateriaal options include timber cladding, metal panels (aluminium, zinc), fiber cement boards, brick veneer, natural stone, and ceramic or porcelain panels, as well as durable vinyl siding. Interior coverings include plaster or gypsum board finishes with paint or wallpaper, ceramic or stone tiles, decorative panels, and specialty wall coverings. Roof coverings may also be categorized as kattemateriaal, such as metal sheets or shingles.

Performance criteria for kattemateriaal involve durability, weather resistance, fire performance, moisture management, thermal insulation, UV stability, and ease of maintenance. Selection depends on climate, building usage, budget, and regulatory requirements, as well as aesthetic considerations and environmental impact.

Installation considerations include substrate condition, moisture barriers, insulation continuity, and sealant detailing. In exterior facades, rainscreen or ventilated systems improve moisture management. Fixing methods vary from mechanical fasteners to adhesives and concealed fixings, with attention to edge details and weather sealing.

Sustainability and standards influence material choice. Recyclability, embodied energy, and indoor air quality are increasingly important, and performance is governed by local codes and international standards (for example, fire classifications and performance testing).
