Insuleeritud

Insuleeritud is an Estonian adjective meaning insulated. The term is used to describe objects, assemblies, or constructions that are provided with some form of insulation to reduce the transfer of heat, sound, or electricity.

Thermal insulation is the most common context in which insuleeritud is used, especially in buildings. Thermal insulation minimizes heat loss in winter and heat gain in summer, improving energy efficiency. Its performance is commonly expressed by thermal resistance (R-value or RSI) and thermal transmittance (U-value). Good practice includes continuous insulation, proper air barriers, and minimization of thermal bridging.

Common insulation materials include mineral wool, fiberglass, expanded or extruded polystyrene, polyurethane or polyisocyanurate foams, and natural materials such as cellulose, cork, or wood fiber composites. Selection depends on thermal performance, fire resistance, moisture behavior, and environmental considerations.

Electrical insulation refers to materials or configurations that prevent current flow where it is not desired. Insulators such as porcelain, glass, epoxy, or polymeric coatings are used in cables, transformers, and electrical equipment to maintain safety and performance.

Acoustic insulation reduces sound transmission between spaces, often using dense materials, absorptive layers, or decoupled assemblies. In buildings, combining mass, damping, and sealed junctions helps control noise.

Regulatory frameworks set requirements for insulation levels, fire performance, and energy use. Life-cycle considerations include embodied energy and sustainability.
