Façade Air and Water Infiltration
Water infiltration and air infiltration resistance of glass facade systems rely on the quality of glazing seals and internal drainage systems. The outer glazing seal system provides the first line of defence against water infiltration. In contrast, the interior glazing seals provide resistance against air infiltration, a critical aspect of pressure equalization. The internal drainage system typically consists of end dams or zone dams at the ends of each horizontal mullion and weeps that allow water to drain to the exterior. Deterioration of uncovered sealant joints can also impact the water and air infiltration resistance of a curtain wall or window system.
Water and air infiltration issues are the most common problems with curtain wall systems. When manifested in recently installed curtain wall systems, they typically indicate installation or design issues.
Replace Broken Glass panels or damaged Aluminum cladding panels (ACP)
The appearance of the building facade, in particular, the glass and Aluminium cladding, can be affected by long-term exposure to direct sunlight. Such change in appearance can consist of fading or peeling of metal frame finishes and staining of glass and metal elements due to sealant leakage or etching of the glass and metal because of the alkalinity of adjacent cementitious materials.
Fading of metal frame systems is directly related to the quality of finishes and exposure to ultraviolet (UV). Peeling metal finishes can be due to improper surface preparation during the original coating process or exposure to salts in service (such as areas of curtain walls in cornish Dubai or Abu Dhabi environments).
Glass staining is sometimes referred to as "Foggy glass panels." This phenomenon has been well-documented and is typically due to the migration of plasticizers from older silicone sealants that may have been used as glazing, used in restorations, or used in neighbouring joints. This phenomenon can also impact the metal framing components.
Replace façade sealant and gasket
One of the most common erosion mechanisms in curtain wall systems is the degradation of glazing gaskets. Most curtain wall designs depend on preformed gaskets for a watertight seal between the glass or spandrel panels and metal parts. These gaskets act as the preliminary seal against air and water infiltration. Glazing gaskets are produced of various materials, including neoprene, EPDM, silicone, and other elastomeric materials. Gaskets are either moulded or extruded. Extruded gaskets must be cut to length and jointed with adhesive at the mitred corners.
Moulded gaskets have integrated mitred corners with no seams and typically provide a better seal at the corners. In some cases, the corners are mitre-cut at the appropriate angle and not adhered to. In other cases, the gaskets may be cut at 90-degree angles and butted against the gasket on the adjacent side of the glazing.
Inside set-glass curtain wall systems typically incorporate a combination of a preset "bedding" gasket on the surface and a "drive-in" wedge gasket on the interior. Outside set-glass systems have a "bedding" gasket on the interior and a "drive-in" wedge gasket on the exterior. Preset gaskets can typically not be extracted and replaced easily, while drive-in wedge gaskets can.
Depending on gasket type, prolonged exposure to UV can result in hardening, shrinkage, and cracking of the gasket material. In some cases, gasket shrinkage is significant enough that the gaskets shrink away from glass corners, resulting in a loss of watertight ness. Moulded gaskets can pull out of their retaining grooves due to shrinkage, and extruded gaskets can shrink away from the corners, leaving the corners with no waterproofing defence. Although most curtain wall designs include internal weep systems, a weep system typically cannot accommodate considerable water infiltration due to gasket deterioration and shrinkage.
Exterior Sealants and Expansion Joints
Curtain walls systems rely on exterior sealants and expansion joints to stop air and water infiltration. Many building façades are composed of curtain wall sections bordering other cladding systems. In such designs, the exterior sealant joints between the curtain wall system and the adjacent cladding materials are crucial in keeping the watertight integrity of the façade. Sealants are also used to form expansion joints within the curtain wall systems.
It should be noted that due to their low thermal mass, curtain wall systems are subject to frequent thermal movements. If sealant joints within the system or around the system's perimeter are not appropriately designed, failures can occur. Proper design of the joint, adequate selection of the sealant materials, and proper installation are crucial to ensuring the long-term performance of the joints. Industry standards such as ASTM C1472,1, ASTM C1193,2 and SWR Institute's "Sealants: The Professional's Guide" provide good information.
Building expansion joint accessories are often integrated into the building façade to accommodate construction movements. If not correctly integrated with the curtain wall system or unable to accommodate in-service movements, expansion joints can also be a water source or air infiltration.
Structural and Safety Issues
Much other distress or deterioration mechanisms in curtain wall systems can pose structural or safety concerns. These include, but are not limited to, loose mullion caps, glass breakage, and corroded or distressed connections.
Many curtain wall systems incorporate snapped-on, prefinished aluminium extrusions that cover the mullions. Typically, these components only serve an aesthetic operation and do not affect the system's performance. However, in some thermally enhanced systems, mullion caps can contribute to additional thermal performance for the system. The proper fit of these components is dependent on tight manufacturing tolerances. Temperature changes, frequent removal and reinstallation, or improper manufacturing tolerances can result in the dislodgement of these covers. If dislodged, mullion covers can pose a serious fall hazard.
Curtain wall frames are subjected to extreme thermal changes. Unlike other construction envelope systems such as masonry, stone, or concrete, curtain wall systems have a small thermal mass. This results in rapid thermal changes in the system elements. A masonry wall may take several hours to reach peak temperatures. A curtain wall can reach these temperatures after a short time of direct sunlight on a warm summer day. Conversely, a curtain wall system can also cool rapidly due to its small thermal mass.
The small thermal mass of curtain wall systems, combined with the extensive use of aluminium in curtain wall frames (aluminium has a relatively high thermal expansion coefficient), makes curtain wall systems particularly prone to thermal-induced deterioration. The thermal expansion of a 6m tall aluminium mullion subjected to a -5 to 75-degree temperature is over 16mm. While the curtain wall system can have such significant movements, the structural frame of the building, which is protected from temperature fluctuations, undergoes tiny thermal movement. This results in differential thermal movements between the curtain wall and the building frame. Building frame deformations such as creep and deflections exacerbate differential movement between the curtain wall system and the building frame. The connections of the curtain wall system to the building frame must be designed to accommodate such movements while properly transferring curtain wall gravity and wind loads to the building frame.
