Methods for heat retention and indoor warmth

Overview

Practices for maintaining warmth in extreme cold focus on both structural insulation and traditional heating technologies. In residential settings, heat retention is achieved through high-quality thermal insulation, triple-glazed windows, and ‘blower door tests’ to identify air leaks. Specialized textiles, such as traditional Norwegian knitwear that uses a multi-color technique to trap air between threads, also serve as insulators.

Indoor warmth can be further managed through household adjustments, such as using curtains to create thermal barriers or utilizing sunlight to warm surfaces. Regional traditional systems include the ‘kang’ platform bed in China, which uses channels to direct warm air through clay, as well as the Korean ‘ondol’ floor heating system and the Japanese ‘kotatsu’ heated table.
