luftsisolerade

Luftisolerade refers to a type of insulation designed to create an air gap for thermal resistance. This air gap, often called a "luftspalt" in Swedish, is a fundamental principle in building physics for reducing heat transfer. The effectiveness of luftisolerade relies on the insulating properties of still air, which is a poor conductor of heat.

In construction, this can be achieved in several ways. For instance, it can involve creating a void between layers of building materials. This void might be intentionally left empty or filled with a material that still allows for significant air movement within its structure, such as certain types of loose-fill insulation. The principle is to prevent convective heat transfer by minimizing the movement of air through the insulated space.

This concept is applied in various contexts, including walls, roofs, and floors. It can also be a feature in specialized products where a sealed air space is maintained to prevent thermal bridging. The goal is to improve the energy efficiency of buildings by reducing the amount of heat lost in winter and gained in summer. Understanding and correctly implementing luftisolerade is crucial for achieving optimal thermal performance in building envelopes.
