Typhoon Shutters
Hurricane coverings, commonly known as shutters, are used in hurricane mitigation to protect houses and other structures from damage caused by storms. Hurricane shutters are used to prevent windows from being broken by flying objects during a storm. Although the negative pressure caused by high-speed wind flowing over a building roof can cause the roof to fail with the building envelope intact, broken windows allow the air pressure to rise inside a building, creating an even greater pressure difference and increasing the likelihood of roof failure. Shutters are frequently constructed from steel or aluminium, but homeowners sometimes use the low-cost alternative of plywood. The shutters are affixed to the outside of the building with screws, hurricane clips, or a track system. Advanced shutters may be motorized, and they may fold away when not in use. Types of hurricane coverings Three major types of shutters are known alternatively as panel systems. They are usually made of pl ...

Roller Shutter
A roller shutter, security shutter, coiling door, roller door or sectional overhead door is a specialized type of door or window shutter consisting of multiple horizontal slats, bars, or web systems interconnected through hinges. The mechanism involves lifting the door to open it and lowering it to close. In the case of larger doors, an automated, motorized system may be employed. This versatile design offers comprehensive protection against various elements, including wind, rain, fire, and theft. When utilized as a shutter in front of windows, it serves as a formidable deterrent against vandalism and thwarting burglary attempts, reinforcing the security of the enclosed space. Applications Roller shutters have many applications including doors for vans, Garage (house), garages, kitchens, schools, prisons and warehouses. They are also commonly used as window blinds in some European countries, such as Italy, Germany, France and Spain. These shutters serve as insulation in locati ...

Coastal Construction
A coast (coastline, shoreline, seashore) is the land next to the sea or the line that forms the boundary between the land and the ocean or a lake. Coasts are influenced by the topography of the surrounding landscape and by aquatic erosion, such as that caused by wind wave, waves. The geology, geological composition of rock (geology), rock and soil dictates the type of shore that is created. Earth has about of coastline. Coasts are important zones in natural ecosystems, often home to a wide range of biodiversity. On land, they harbor ecosystems, such as freshwater marsh, freshwater or estuary, estuarine wetlands, that are important for birds and other terrestrial animals. In wave-protected areas, coasts harbor salt marshes, mangroves, and seagrass meadow, seagrasses, all of which can provide nursery habitat for finfish, shellfish, and other aquatic animals. Rocky shores are usually found along exposed coasts and provide habitat for a wide range of sessility (motility), sessile ...

Building
A building or edifice is an enclosed Structure#Load-bearing, structure with a roof, walls and window, windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, monument, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the :Human habitats, human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much architecture, artistic expression. ...

Window Shutter
A window shutter is a solid and stable window covering usually consisting of a frame of vertical stiles and horizontal rails (top, centre and bottom). Set within this frame can be louvers (both operable or fixed, horizontal or vertical), solid panels, fabric, glass and almost any other item that can be mounted within a frame. Shutters may be employed for a variety of reasons, including controlling the amount of sunlight that enters a room, to provide privacy, security, to protect against weather or unwanted intrusion or damage and to enhance the aesthetics of a building. Depending on the application, and the construction of the window frame, shutters can be mounted to fit within the opening or to overlap the opening. The term window shutter includes both interior shutters, used on the inside of a house or building, and exterior shutters, used on the outside of a structure. On some styles of buildings it is common to have shutters to cover the doors as well as the windows. Int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Product Certification
Product certification or product qualification is the process of certifying that a certain product has passed performance tests and quality assurance tests, and meets qualification criteria stipulated in contracts, regulations, or specifications (sometimes called "certification schemes" in the product certification industry). Most product certification bodies (or product certifiers) are accredited to or aligned with ISO/IEC 17065 Conformity assessment—Requirements for bodies certifying products, processes and services (previously ISO/IEC Guide 65:1996)ISO/IEC Guide 65:1996 an international standard for ensuring competence in those organizations performing product, process and service certifications. The organizations that perform this accreditation are called Accreditation Bodies, and they themselves are assessed by international peers against the ISO 17011 standard. Examples of some certification schemes include the Safety Equipment Institute (SEI) for PPE, the U.S. Fed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane-proof Building
Tornadoes, cyclones, and other storms with strong winds damage or destroy many buildings. However, with proper design and construction, the damage to buildings by these forces can be greatly reduced. A variety of methods can help a building survive strong winds and storm surge. Storm surge considerations Waves along coastal areas can destroy many buildings. Buildings should preferably be built on high ground to avoid waves. If waves can reach the building site, the building should be elevated on steel, concrete, or wooden pilings or anchored to solid rock. Wind loading considerations Foundation Wind on the roof surfaces can cause negative pressures that create a lifting force sufficient to lift the roof off the building. Once this occurs, the building is weakened considerably, and the rest will likely fail as well. To minimize this vulnerability, the upper structure ought to be anchored through the walls to the foundation. Several methods can be used to anchor the roof. Typica ...

Hurricane Preparedness
Cyclone mitigation encompasses the actions and planning taken before a tropical cyclone strikes to mitigate damage and injury from the storm. Knowledge of tropical cyclone impacts on an area help plan for future possibilities. Preparedness may involve preparations made by individuals as well as centralized efforts by governments or other organizations. Tracking storms during the tropical cyclone season helps individuals know current threats. Regional Specialized Meteorological Centers and Tropical Cyclone Warning Centers provide current information and forecasts to help individuals make the best decision possible. Potential impacts Tropical cyclones out at sea cause large waves, heavy rain (meteorology), heavy rain, flood and high winds, disrupting international shipping and, at times, causing shipwrecks. On land, strong winds can damage or destroy vehicles, buildings, bridges, and other outside objects, turning loose debris into deadly flying projectiles. The storm surg ...

Florida Building Code
The Florida Building Code (FBC) is a set of standards designed by the Florida Building Commission for the construction of buildings in the US state of Florida. Many regulations and guidelines distributed are important benchmarks regarding hurricane protection. Miami-Dade County was the first in Florida to certify hurricane-resistant standards for structures which the Florida Building Code subsequently enacted across all requirements for hurricane-resistant buildings. Many other states reference the requirements set in the Florida Building codes, or have developed their own requirements for hurricanes. The Florida Building Code is also based upon the International Building Code (IBC) used in the United States. Hurricane guidelines The 2010 edition of the Florida Building Code introduced significant changes to wind load design, in particular the presentation of the wind speed maps. The Miami-Dade and Broward County norms, are both included in the High-Velocity Hurricane Zones (H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthetic Rubber
A synthetic rubber is an artificial elastomer. They are polymers synthesized from petroleum byproducts. About of rubber is produced annually in the United States, and of that amount two thirds are synthetic. Synthetic rubber, just like natural rubber, has many uses in the automotive industry for tires, door and window profiles, seals such as O-rings and gaskets, hoses, belts, matting, and flooring. They offer a different range of physical and chemical properties which can improve the reliability of a given product or application. Synthetic rubbers are superior to natural rubbers in two major respects: thermal stability, and resistance to oils and related compounds. They are more resistant to oxidizing agents, such as oxygen and ozone which can reduce the life of products like tires. History The expanded use of bicycles, and particularly their pneumatic tires, starting in the 1890s, created increased demand for rubber. In 1909, a team headed by Fritz Hofmann, working at ...

Polypropylene
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer Propene, propylene. Polypropylene belongs to the group of polyolefins and is Crystallization of polymers#Degree of crystallinity, partially crystalline and Chemical polarity#Nonpolar molecules, non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. Polypropylene is the second-most widely produced Commodity plastics, commodity plastic (after polyethylene). History Phillips Petroleum chemists J. Paul Hogan and Robert Banks (chemist), Robert Banks first demonstrated the polymerization of propylene in 1951. The stereoselective polymerization to the isotactic was discovered by Giulio Natta and Karl Rehn in March 1954. This pioneering discovery led to large-scale commercial producti ...

Hurricane
A tropical cyclone is a rapidly rotating storm system with a low-pressure area, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is called a hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean. A typhoon is the same thing which occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of or more. Tropical cyclones typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water from the ocean ...
