The correct spelling for the strip that seals gaps between doors or windows and frames is "draught strip". The word "draught" is pronounced as /drɑːft/ in IPA phonetic transcription. This spelling originates from the Old English word "drēahnian", which means "to dry out or drain". The modern spelling with "au" became standard in the 18th century as a way to differentiate between the verb "draft" and the noun "draught", which refers to a current of air or a serving of a drink.
A draught strip, also known as a weather strip or weatherseal, is an essential component used in various applications to prevent the passage of air and water between two surfaces. It is typically made of a flexible material such as rubber, silicone, or foam, which is attached to the edge of a door, window, or any other opening where air leakage is likely to occur.
The main purpose of a draught strip is to create a tight seal that minimizes energy loss by reducing air infiltration. It acts as a barrier against drafts, cold air, and external elements from entering a room or building. Additionally, it helps to maintain a comfortable indoor environment by preventing the escape of conditioned air, resulting in energy savings and reduced utility costs.
Draught strips are designed to be easily installed and are available in various shapes, sizes, and materials to suit different types of openings. Common types include adhesive-backed strips, self-adhesive foam tapes, magnetic strips, or brush-style seals. Some draught strips also provide soundproofing properties, enhancing acoustic insulation.
Regular maintenance and replacement of draught strips are crucial for their effective functioning. Over time, these strips may degrade, wear out, or lose their elasticity, compromising their ability to prevent air leakage. Therefore, it is recommended to inspect and replace draught strips as needed to ensure optimal sealing and energy efficiency.
The etymology of the word "draught strip" can be traced back to the Old English word "dræht", which meant "a pulling, a drawing". This word evolved from the Proto-Germanic word "*drahtiz", meaning "a pull". In Middle English, the term "draught" referred to a drawing or pulling force, especially regarding air or fluid movement. The word "strip" originated from the Old English word "striep", which meant "a long, narrow piece". Combining these two elements, the term "draught strip" emerged, describing a narrow piece or strip used to prevent drafts or the flow of air.
The term "draught strip" is mainly used in British English, while the American English equivalent is typically referred to as a "weatherstripping" or "draft stopper". Nonetheless, the etymology of the word remains the same regardless of regional variations.
