Học thuậtThân thiện
Definition
Noun: A storm sash is a secondary window frame, usually containing glass or a transparent material, installed on the exterior of a primary window. Its primary function is to provide an additional layer of insulation and protection against severe weather conditions, such as winter cold, wind, rain, and snow.
Usage
A storm sash is used to improve a building's energy efficiency and weatherproofing. It is typically installed seasonally or permanently over an existing window. * Installing storm sashes can significantly reduce heating costs in the winter. * Before the hurricane, they secured the storm sash over the living room window. * The old storm sash was removed in the spring to allow the main window to be opened.
Advanced Usage
- Historical Context: In older architecture, especially before the widespread use of double-pane insulated glass, storm sashes were a common and essential feature for thermal comfort.
- Technical Specification: A well-fitted storm sash creates a dead air space between itself and the primary window, which acts as an insulating barrier.
