The Curtain and the Wall: A Modern Journey Along Europe's Cold War Border

Product Information

Blast resistant glazing consists of laminated glass, which is meant to break but not separate from the mullions. Similar technology is used in hurricane-prone areas for impact protection from wind-borne debris. The development and widespread use of structural steel and later reinforced concrete allowed relatively small columns to support large loads. The exterior walls could be non-load bearing, and thus much lighter and more open than load-bearing walls of the past. This gave way to increased use of glass as an exterior façade, and the modern-day curtain wall was born. Curtain walls and perimeter sealants require maintenance to maximize service life. Perimeter sealants, properly designed and installed, have a typical service life of 10 to 15 years. Removal and replacement of perimeter sealants require meticulous surface preparation and proper detailing.

Since these walls are non-structural, they can be made out of materials like aluminium, a very lightweight and durable choice. This section does not cite any sources.

( April 2015) ( Learn how and when to remove this template message)Curtain walls may be designed as "systems" integrating frame, wall panel, and weatherproofing materials. Steel frames have largely given way to aluminum extrusions. Glass is typically used for infill because it can reduce construction costs, provide an architecturally pleasing look, and allow natural light to penetrate deeper within the building. However, glass also makes the effects of light on visual comfort and solar heat gain in a building more difficult to control. Other common infills include stone veneer, metal panels, louvres, and operable windows or vents.

Digital Reads A Curse For True Love : the thrilling final book in the Once Upon a Broken Heart series That’s where curtain walling comes into consideration, with its modern looks and elegance that definitely can change the style of a building.Well, there is the possibility, for sure. But all the brightness can be controlled with darker flooring or darker walls, for instance. Another way to deal with it is to simply hang translucent curtains inside the curtain walling, so the light is allowed to come in, but not in its full force. Since curtain walling is installed from the outside of the building, the process is subject to delay due to weather conditions. 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.

A common feature in curtain wall technology, the rainscreen principle theorizes that equilibrium of air pressure between the outside and inside of the "rainscreen" prevents water penetration into the building. For example, the glass is captured between an inner and an outer gasket in a space called the glazing rebate. The glazing rebate is ventilated to the exterior so that the pressure on the inner and outer sides of the outer gasket is the same. When the pressure is equal across this gasket, water cannot be drawn through joints or defects in the gasket. Every literary festival stays in an author’s mind for slightly individual reasons. I shall remember the Oxford festival for: It transmits wind induced loads to the primary structure. It also resists the seismic accelerations keeping the occupants comfortable. Other than this it has to resist gravity loads coming over it.There is an old Soviet joke about Kremlin propaganda,” he said: “’They lied to use about communism. But everything they said about capitalism was true.’”
