👉what type of glass used for curtain walls and why?
💫Curtain walls primarily use insulated glass units (IGUs), especially with low-emissivity (Low-E) coatings, for their thermal performance and energy efficiency.
⏺Other common types include tempered glass and laminated glass for safety and durability.
⏺The specific glass is chosen based on performance needs like energy conservation, glare reduction, safety, and sound insulation.
🚧Insulated Glass Units (IGUs): Also called double or triple glazing, these units have at least two panes of glass with a sealed space between them filled with air or an inert gas.
▶️Why: This design provides excellent thermal insulation, reducing heating and cooling costs, and offers sound dampening.
🚧Tempered Glass: This is glass that has been heat-treated to increase its strength.
🏷Why: It is much stronger than regular glass and, when it does break, it shatters into small, relatively harmless pieces, making it a crucial safety feature.
🚧Laminated Glass: This is made of two or more layers of glass with a plastic interlayer, such as polyvinyl butyral (PVB), sandwiched between them.
⏺Why: It offers enhanced security and impact resistance, as the interlayer holds the glass fragments together if it breaks, and also provides better sound insulation.
🚧Low-E Coatings: These are microscopically thin, transparent coatings applied to one or more glass surfaces, usually within an IGU.
⏺Why: Low-emissivity (Low-E) coatings reflect infrared light, which keeps heat inside during the winter and outside during the summer.
⏺This significantly improves a building's energy efficiency and thermal performance.
