eristevuotoihin

Eristevuotoihin refers to voids or air pockets within an insulation layer or in cavities adjacent to insulation that reduce the effective thermal resistance. Voids can form when insulation boards do not fit tightly, when loose-fill materials settle or migrate, when cavities around penetrations are not properly filled, or when insulation is compressed during installation. They may also arise from moisture-induced swelling or damage to the material.

Voids act as thermal bridges, creating uneven temperature distribution and increasing heat loss. They can lead to higher energy consumption, condensation on cold surfaces, and, if moisture is present, mold growth and material deterioration. In some cases, voids also reduce acoustic insulation and increase air leakage.

Identification is typically done through visual inspection and, more comprehensively, by infrared thermography or blower-door tests. Destructive testing or core sampling can quantify void size and distribution in some installations.

Prevention focuses on proper installation practice: using the correct thickness and density of insulation, avoiding compression, ensuring tight joints between boards, and sealing around penetrations with appropriate tapes or sealants. A continuous air and vapor barrier, proper ventilation, and moisture control are important. Remediation may involve re-foaming or re-filling voids with the same material, resealing joints, or replacing affected insulation where necessary.

Eristevuotoihin are a consideration in energy efficiency assessments and building durability. Addressing voids promptly helps maintain insulation performance and indoor air quality.
