loftdrátt

Loftdrátt is a term originating from Icelandic that translates to "air pull" or "draft." It generally refers to a noticeable flow of air, often perceived as undesirable, within a building or enclosed space. This phenomenon is most commonly associated with heat loss and can significantly impact a building's energy efficiency and occupant comfort.

The presence of loftdrátt can be caused by several factors, including gaps and cracks in the building envelope, poorly sealed windows and doors, and inadequate insulation. Air can infiltrate from the outside or exfiltrate from the inside, leading to a continuous circulation of air. This movement of air can carry heat with it, making it harder to maintain a stable indoor temperature and increasing heating costs.

Identifying and addressing loftdrátt is a crucial aspect of building diagnostics and energy retrofitting. Techniques such as thermal imaging and smoke tests can help pinpoint the sources of drafts. Remediation typically involves sealing these openings with appropriate materials like caulk, weatherstripping, or expanding foam, and improving insulation levels. By minimizing loftdrátt, building owners can enhance comfort, reduce energy consumption, and contribute to a more sustainable built environment.
