The Curtain and The Wall: A Modern Journey along Europe…

Italian Dinner Celebrating the Programme of Italian Literature and Culture SOLD OUT Exeter College: Hall 7:15pm Fri 31 Friday, 31 March 2023 See this event Thermal loads are induced in a curtain wall system because aluminum has a relatively high coefficient of thermal expansion. This means that over the span of a couple of floors, the curtain wall will expand and contract some distance, relative to its length and the temperature differential. This expansion and contraction is accounted for by cutting horizontal mullions slightly short and allowing a space between the horizontal and vertical mullions. In unitized curtain wall, a gap is left between units, which is sealed from air and water penetration by gaskets. Vertically, anchors carrying wind load only (not dead load) are slotted to account for movement. Incidentally, this slot also accounts for live load deflection and creep in the floor slabs of the building structure. Past studies have showed that curtain walls seem to be resistant against lateral forces mainly earthquake, but there is measurable amount of damage caused. Even though damage can be repaired, there is economy loss and delay in business activity.At a test pressure of 600 pascals, an air infiltration rate no higher than 1.5m³/hr/m² for fixed glazed panels is permissible, provided there is no evidence of concentrated leakage. Since curtain walling is installed from the outside of the building, the process is subject to delay due to weather conditions. A travel memoir disguised as a political science piece. Filled with lots of irrelevant personal stories, pictures integrated at random places instead of all together at the end, which I didn't like. Truthfully I got nothing of substance from this. The writing could have been tighter, and had more references to the history instead of just verbal regurgitation that relies on trusting the author. I'm sure some people will enjoy this, but it was not for me.

Curry, Anne; Hughes, Michael, eds. (1999), Arms, Armies and Fortifications in the Hundred Years War (illustrated, reprint, reviseded.), Boydell & Brewer, p. 134, ISBN 9780851157559 Wind actions are transferred by the cladding system to the building floors which act as a linear support. Building cladding systems formed of large panels are usually one-way spanning. Each floor level therefore supports one level of wind load on a building. Across 3,000 miles and over eight decades, this epic new people's history of the Cold War makes eye-opening sense of a defining 20th-century conflict—and how it continues to shape our world today.

Eventually silicone sealants or glazing tape were substituted for the glazing compound. Some designs included an outer cap to hold the glass in place and to protect the integrity of the seals. The first curtain wall installed in New York City, in the United Nations Secretariat Building ( Skidmore, Owings & Merrill, 1952), was this type of construction. Earlier modernist examples are the Bauhaus in Dessau (1926) and the Hallidie Building in San Francisco (1918).Thermal conductivity of the curtain wall system is important because of heat loss through the wall, which affects the heating and cooling costs of the building. On a poorly performing curtain wall, condensation may form on the interior of the mullions. This could cause damage to adjacent interior trim and walls. Most curtain wall glazing is fixed, meaning there is no access to the exterior of the building except through doors. However, windows or vents can be glazed into the curtain wall system as well, to provide required ventilation or operable windows. Nearly any window type can be made to fit into a curtain wall system. Deflection limits are typically expressed as the distance between anchor points divided by a constant number. A deflection limit of L/175 is common in curtain wall specifications, based on experience with deflection limits that are unlikely to cause damage to the glass held by the mullion. Say a given curtain wall is anchored at 12-foot (144in) floor heights. The allowable deflection would then be 144/175 = 0.823inches, which means the wall is allowed to deflect inward or outward a maximum of 0.823inches at the maximum wind pressure. However, some panels require stricter movement restrictions, or certainly those that prohibit a torque-like motion.

Relative to other building components, aluminum has a high heat transfer coefficient, meaning that aluminum is a very good conductor of heat. This translates into high heat loss through aluminum (or steel) curtain wall mullions.

The beautiful, modernist Alvar Aalto library, built in the 1930s in what was then part of Finland, and now is in Russian Vyborg A louver is provided in an area where mechanical equipment located inside the building requires ventilation or fresh air to operate. They can also serve as a means of allowing outside air to filter into the building to take advantage of favorable climatic conditions and minimize the usage of energy-consuming HVAC systems. Curtain wall systems can be adapted to accept most types of louver systems to maintain the same architectural sightlines and style while providing desired functionality.
