Awnings
An awning or overhang is a secondary covering attached to the exterior wall of a building. It is typically composed of canvas woven of acrylic, cotton or polyester yarn, or vinyl laminated to polyester fabric that is stretched tightly over a light structure of aluminium, iron or steel, possibly wood or transparent material (used to cover solar thermal panels in the summer, but that must allow as much light as possible in the winter). The configuration of this structure is something of a truss, space frame or planar frame. Awnings are also often constructed of aluminium understructure with aluminium sheeting. These aluminium awnings are often used when a fabric awning is not a practical application where snow load as well as wind loads may be a factor. Types Actuation Today's awnings come in two basic types: manually operated models which are opened by hand and motorized models which operate by electricity. Each offers its own advantages. Benefits include low-cost affordabi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Acrylic Fiber
Acrylic fibers are synthetic fibers made from a polymer ( polyacrylonitrile) with an average molecular weight of ~100,000, about 1900 monomer units. For a fiber to be called "acrylic" in the US, the polymer must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate. DuPont created the first acrylic fibers in 1941 and trademarked them under the name Orlon. It was first developed in the mid-1940s but was not produced in large quantities until the 1950s. Strong and warm, acrylic fiber is often used for sweaters and tracksuits and as linings for boots and gloves, as well as in furnishing fabrics and carpets. It is manufactured as a filament, then cut into short staple lengths similar to wool hairs, and spun into yarn. Modacrylic is a modified acrylic fiber that contains at least 35% and at most 85% acrylonitrile. Vinylidene chloride or vinyl bromide used in modacrylic give the fiber flame retardant properties. End-uses of modacry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Window Shade
A window blind is a type of window covering. There are many different kinds of window blinds which use a variety of control systems. A typical window blind is made up of several long horizontal or vertical slats of various types of hard material, including wood, plastic or metal which are held together by cords that run through the blind slats. Vertical blinds run along a track system which can tilt open and closed and move side-to-side. Window blinds can be manoeuvred with either a manual or remote control by rotating them from an open position, with slats spaced out, to a closed position where slats overlap and block out most of the light. There are also several types of window coverings, called shades, that use a single piece of soft material instead of slats. The term window blinds can also be used to describe window coverings more broadly. In this context window blinds include almost every type of window covering, whether it is a hard or soft material; i.e. shutters, rol ...

Baden-Baden Kurmuschel
Baden-Baden () is a spa town in the state of Baden-Württemberg, south-western Germany, at the north-western border of the Black Forest mountain range on the small river Oos, ten kilometres (six miles) east of the Rhine, the border with France, and forty kilometres (twenty-five miles) north-east of Strasbourg, France. In 2021, the town became part of the transnational UNESCO World Heritage Site under the name "Great Spa Towns of Europe", because of its famous spas and architecture that exemplifies the popularity of spa towns in Europe in the 18th through 20th centuries. Name The springs at Baden-Baden were known to the Romans as "" ("The Waters") and "" (" Aurelia-of-the-Waters") after M. Aurelius Severus Alexander Augustus. In modern German, "" is a noun meaning "bathing", but "Baden", the original name of the town, derives from an earlier plural form of ' ( "bath"). (Modern German uses the plural form '.) As with the English placename "Bath", other Badens are at hot spr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
