Curtain Walls in Commercial Buildings

Summary: Curtain wall systems have evolved to become essential elements in contemporary architecture.

FREMONT, CA: Curtain wall systems have become a prominent feature in modern architecture, offering aesthetic appeal and functional advantages. These systems, often accompanied by commercial glazing, play a pivotal role in shaping the appearance and performance of contemporary buildings.

At its core, a curtain wall is a non-load-bearing, thin outer wall attached to the exterior of a building. While it does not provide structural support to the building's floors or roof, it serves several crucial purposes. One of its primary functions is to act as a barrier, preventing moisture and air from infiltrating the building's interior. This protection is vital for maintaining the internal spaces' integrity and ensuring the occupants' comfort.

Beyond moisture and air resistance, curtain wall systems contribute to a building's overall stability. By efficiently distributing horizontal loads caused by gravity and wind, these systems enhance a structure's ability to withstand external forces. This aspect of curtain wall construction is particularly valuable in regions prone to adverse weather conditions, as it provides wind protection and structural support.

Moisture infiltration, especially in rain and snow, can harm a building if left unchecked. It can lead to damp insulation, reducing energy efficiency and potentially causing structural damage over time. Curtain wall systems are a robust defense against such moisture intrusion, safeguarding the building's interior and long-term durability.

In today's construction landscape, sustainability and energy efficiency are paramount considerations. Building owners and occupants increasingly focus on minimizing energy consumption and environmental impact. Modern curtain wall systems are designed with these concerns and offer significant benefits.

One of the notable advantages of curtain walls is their ability to substantially reduce a building's heating demands. Some systems can achieve more than 30 percent reduction in heating requirements, making them a valuable asset for energy-conscious projects. Additionally, these systems effectively limit the penetration of harmful UV rays, creating a healthier indoor environment for occupants.
