The terminology of doors and windows is very important in the construction industry. They help us understand the structure, function and performance of doors and windows. In buildings, doors and windows are not only used to provide light and ventilation, but also have important safety and energy efficiency functions.The following are some common professional terms in the door and window industry:
1. Window type/door type
·Inward-opening Window/Outward-opening Window: refers to the opening direction of the window, inward-opening windows open to the interior, and outward-opening windows open to the outside.
·Single-leaf Window/Double-leaf Window: Single-leaf windows have only one window leaf, and double-leaf windows have two window leaves that can be opened separately.
·Double-leaf Door/Single-leaf Door: Single-leaf doors have only one door leaf that can be opened, and double-leaf doors have two door leaves that can be opened.
2.Profiles
·aluminum alloy profile: material used for door and window frames, with advantages such as light weight, high strength and corrosion resistance.
·Thermal Break aluminum profile: using insulation strips (such as polyamide) to connect the inner and outer aluminum profiles to effectively block the conduction of heat and enhance the thermal insulation performance.
·Stainless steel profiles: Strong corrosion resistance, usually used in high-end door and window products.
·Single-layer glass: refers to only one layer of glass, usually used for windows with low sound insulation and heat insulation requirements.
·Insulating glass: It is composed of two or more pieces of glass, with a cavity between the glass and filled with inert gas (such as argon), which has good heat insulation and sound insulation.
·Double-layer glass: Similar to insulating glass, it is usually composed of two layers of glass and a gas layer, which can provide good heat insulation and sound insulation.
·Tempered glass: A heat-treated glass with greater strength than ordinary glass, and when broken, it is in small particles, which is safer.
·Low-E glass: Low-radiation glass, with high thermal insulation, can effectively block ultraviolet and infrared rays, and improve energy efficiency.
·Bulletproof glass: It is composed of multiple layers of special glass and plastic layers, which can effectively prevent bullet penetration.
4. Hardware accessories
·Hinge: Metal fittings that connect door and window frames and window sashes, allowing doors and windows to be opened and closed.
·Locks: Accessories used for opening and closing doors and windows and for safety protection.
·Pulleys: Used to push and pull doors and windows to ensure smooth sliding of windows or doors.
·Sealing strips: Used to seal the edges of doors and windows to prevent the entry of air, moisture, dust, etc., and improve the windproof and waterproof performance of doors and windows.
·Hinge: Rotating parts that connect door and window sashes to window frames, allowing window sashes to open and close.
5.Technology
·Thermal insulation performance: The ability of doors and windows to block external heat from being conducted into the room, which is usually related to the window frame material and glass structure.
·Sound insulation performance: The noise isolation effect of doors and windows is usually related to the type of glass and the sealing of the window frame.
·Air tightness: Whether doors and windows can effectively prevent air infiltration, affecting the energy efficiency and comfort of doors and windows.
·Water tightness: Whether doors and windows can prevent moisture infiltration and avoid rain intrusion into the room.
·Wind pressure resistance: The ability of doors and windows to withstand external wind force, which is especially important in high-rise buildings.
·Anti-theft performance: The ability of doors and windows to prevent illegal intruders from entering the building, usually involving solid frames, hardware accessories and locks.
6. Door and window installation method
·Inward opening and inward tilting: The window sash can be opened inward or tilted outward (such as some inward opening windows or outward opening windows with dual opening functions).
·Outward opening and outward tilting: The window can be opened outward and has a tilting function, which is suitable for ventilation and dehumidification.
·Top opening window: The window opens from the top, which is suitable for windows at higher positions.
·Energy-saving windows: have good thermal insulation performance, can effectively reduce energy consumption, and are suitable for energy-saving buildings.
·Smart windows: integrated automatic control systems, such as windows that can automatically open or close according to indoor temperature or climate changes.
·Fireproof windows: windows specially designed to prevent the spread of fire, usually using fireproof glass and special sealing design.
·Wind-resistant windows: windows specially designed to withstand strong winds, usually suitable for areas with strong winds such as seaside and mountainous areas.
These terms help industry personnel describe the various functions, structures and technical requirements of doors and windows. In practical applications, it is very important to choose the appropriate door and window type, material and technology according to the design requirements and functional requirements of the building.
