Sandwichelementti

Sandwichelementti, often referred to as sandwich panels, are a type of building material consisting of three layers. The core of the sandwich element is typically made of a lightweight material such as expanded polystyrene (EPS), extruded polystyrene (XPS), mineral wool, or polyurethane foam. This core material is bonded to two outer facings, which are usually thin sheets of metal, such as steel or aluminum, but can also be made from materials like plywood or fiberglass.

The construction of sandwichelementti provides a combination of strength and insulation. The rigid facings offer structural integrity and resistance to bending, while the insulating core provides thermal and acoustic properties. This design makes them suitable for a wide range of applications, including roofing, walls, and partitions in industrial buildings, commercial structures, and even residential homes. They are valued for their speed of installation, as large panels can cover significant areas quickly, and their lightweight nature simplifies transportation and handling on site.

The manufacturing process typically involves the continuous lamination of the core material between the facings under controlled pressure and temperature. This results in a uniform and durable product. Sandwichelementti are available in various thicknesses and facing profiles to meet specific performance requirements, such as fire resistance, load-bearing capacity, and aesthetic preferences. Their use contributes to energy efficiency in buildings due to their inherent insulation capabilities.
