Curtain walls are non-load-bearing exterior walls that are attached to a building’s structural frame. They provide a stylish and functional façade for buildings, while also offering several other benefits, such as:
- Improved energy efficiency: Curtain walls can help to reduce heat loss in the winter and heat gain in the summer, which can lead to significant energy savings.
- Enhanced curb appeal: Curtain walls can give a building a modern and sophisticated look, which can increase its value and attract tenants or buyers.
- Increased occupant comfort: Curtain walls can help to reduce noise levels and improve air quality inside a building, which can lead to a more comfortable and productive environment for occupants.
