jäykkäeristettyjä

jäykkäeristettyjä is a Finnish term that translates to "rigidly insulated" or "stiffly insulated" in English. It refers to a construction method where insulation materials are installed in a way that maintains their structural integrity and prevents them from deforming or compressing. This is typically achieved by using rigid insulation boards or by ensuring a tight fit of the insulation within the building structure.

The primary benefit of jäykkäeristettyjä construction is its effectiveness in preventing thermal bridging. Thermal bridging occurs when materials with lower thermal resistance, such as structural elements, create a pathway for heat to escape or enter a building. By using rigid insulation that fills the entire cavity and is properly sealed, these thermal bridges are minimized, leading to improved energy efficiency and a more comfortable indoor environment.

This insulation technique is often employed in external wall insulation systems, roofs, and foundations. The rigidity of the insulation ensures that it remains in place over time, even under pressure or potential settling of the building. It can also contribute to the overall structural stability of the building envelope.

In practice, jäykkäeristettyjä might involve using materials like extruded polystyrene (XPS), expanded polystyrene (EPS), or mineral wool boards that are cut to precise dimensions and fitted snugly into place. Careful attention is paid to sealing joints and interfaces to create a continuous thermal barrier. This method is a key aspect of modern energy-efficient building practices.
