Key Features of Curtain Walls for Libraries

Several important features make curtain walls particularly suited to libraries, helping to meet the unique needs of these public spaces.

1. High-Performance Glazing

• Insulated Glass Units (IGUs): These units consist of multiple layers of glass with an air gap, providing effective thermal insulation. This is essential for maintaining a comfortable indoor climate without relying too heavily on HVAC systems.
• Low-E Glass: Low-emissivity glass coatings improve energy efficiency by reflecting infrared light and reducing heat transfer. This helps to control the building’s temperature while still allowing natural light to flood the interior.
• Solar Control Glass: To prevent overheating from direct sunlight, solar control glass can be used to minimize heat gain and glare while still allowing daylight to enter the library’s interior.

2. Acoustic Glass

• Laminated and Acoustic Glass: Libraries often need quiet environments, so using acoustic glass or laminated glass in curtain walls helps mitigate external noise and prevent disturbances from urban environments. This ensures that reading and study areas remain peaceful.

3. Shading and Sun Control Devices

• Shading Systems: External shading systems such as louvres, overhangs, or green roofs can be integrated into curtain walls to help reduce solar heat gain. Internal shading devices, like automated blinds or curtains, also help in controlling light levels and glare.
• Operable Shading Devices: For more control over daylighting, operable shading systems can be installed. These can adjust according to the time of day, providing varying levels of light and heat control as needed
