Løsfyld

Løsfyld, also known as loose fill, refers to a type of insulation material used primarily in the construction and automotive industries. It consists of small, lightweight particles or fibers that are poured or blown into cavities to provide thermal insulation, soundproofing, or structural support. The material is designed to conform to irregular spaces, filling gaps and reducing air infiltration, which enhances energy efficiency.

Common types of løsfyld include cellulose, which is made from recycled paper treated with fire retardants; mineral wool, derived from volcanic rock or slag; and expanded polystyrene beads, often used in automotive applications. Each variant offers distinct properties, such as varying levels of thermal resistance, fire resistance, and moisture absorption.

In construction, løsfyld is frequently applied in wall cavities, attics, and floors to improve thermal performance and reduce heating or cooling costs. It is also used in automotive manufacturing to insulate vehicle interiors, dampening noise and vibration while maintaining structural integrity. The material is typically installed by professionals using specialized equipment to ensure even distribution and optimal effectiveness.

Løsfyld is valued for its versatility and cost-effectiveness compared to rigid insulation panels. However, its performance can be influenced by factors such as installation quality, environmental conditions, and the specific type of material used. Proper handling and installation are essential to maximize its benefits and prevent issues like settling or moisture damage.
