Storm Door
A storm door is a type of door that is installed in front of an exterior access door to protect it from bad weather and allow ventilation (architecture), ventilation. Storm doors generally have interchangeable glass panels and window screen panels to provide visibility and prevent flying insects from entering the home. Construction Storm doors are typically made from wood, aluminum and plastics such as Vinyl group, vinyl (PVC) and fiberglass. There are three basic types of storm doors: full-view, retractable screen, and ventilating. Full-view storm doors typically include a full glass panel and most an interchangeable full screen. Retractable screen storm doors feature a screen that is rolled up into the frame of the storm door when not in use. Ventilating storm doors generally include a full or half screen that is always in position on the storm door. Wood Wood was the original material from which storm doors were made. While wooden screen doors can be visually the most a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fiberglass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doors
A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a ''doorway'' or ''portal''. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the doorway of a building, room, or vehicle. Doors are generally made of a material suited to the door's task. They are commonly attached by hinges, but can move by other means, such as slides or counterbalancing. The door may be able to move in various ways (at angles away from the doorway/portal, by sliding on a plane parallel to the frame, by folding in angles on a parallel plane, or by spinning along an axis at the center of the frame) to allow or prevent ingress or egress. In most cases, a door's interior matches its exterior side. But in other cases (e.g., a vehicle door) the two sides are radically different. Many doors incorporate locking ...

Storm Window
Storm windows are windows that are mounted outside or inside of the main glass windows of a house. Storm windows exist in North America, but are uncommon in continental Europe, where double, triple or quadruple glazing is prevalent. Storm windows can be made of glass, rigid plastic panels, or flexible plastic sheets; and may be permanently or temporarily mounted. They function similarly to insulated glazing. The term may also refer to a small openable flap found in the side window on light aircraft. In the United States, the older style of this window is often referred to as a "storm sash". On modern houses they serve on existing windows in order to improve their thermal insulation and soundproofing. Aside from insulation, storm windows provide an additional measure of protection for homes against damages to costly glass panes during inclement weather such as hail. On older houses, storm windows were installed in autumn when window screens were removed. Later units combined the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storm Room
A safe room or panic room is a fortified room that is installed in a private residence or business to provide a safe shelter, or hiding place, for the inhabitants in the event of a break in, home invasion, tornado, terror attack, or other threat. Safe rooms usually contain communications equipment, so that law enforcement authorities can be contacted. Construction techniques The most basic safe room is simply a closet with the hollow-core door replaced with an exterior-grade solid-core door that has a deadbolt and longer hinge screws and strike-plate screws to resist battering. Sometimes, the ceiling is reinforced, or gated, to prevent easy access from the attic or from an overhead crawl space. More expensive safe rooms have walls and a door reinforced with sheets of steel, Kevlar, or bullet-resistant fiberglass. The hinges and strike plate are often reinforced with long screws. Some safe rooms may also have externally vented ventilation systems and a separate telephone co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storm Drain
A storm drain, storm sewer (United Kingdom, United States, U.S. and Canada), surface water drain/sewer (United Kingdom), or stormwater drain (Australia and New Zealand) is infrastructure designed to Drainage, drain excess rain and ground water from impervious surfaces such as paved streets, car parks, parking lots, footpaths, sidewalks, and roofs. Storm drains vary in design from small residential dry wells to large municipal systems. Drains receive water from street gutters on most motorways, freeways and other busy roads, as well as towns in areas with heavy rainfall that leads to flooding, and coastal towns with regular storms. Even gutters from houses and buildings can connect to the storm drain. Many storm drainage systems are gravity sewers that drain untreated storm water into rivers or streams—so it is unacceptable to pour hazardous substances into the drains. Storm drains sometimes cannot manage the quantity of rain that falls in heavy rains or storms. Inundated drai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storm Cellar
A storm shelter or storm cellar is a type of underground bunker designed to protect the occupants from violent severe weather, particularly tornadoes. They are most frequently seen in the Midwest ("Tornado Alley") and Southeastern United States ("Dixie Alley") where tornadoes are generally frequent and the low water table permits underground structures. Average storm shelter An average storm cellar for a single family is built close enough to the home to allow instant access in an emergency, but not so close that the house could tumble on the door during a storm, trapping the occupants inside. This is also the reason the main door on most storm cellars is mounted at an angle rather than perpendicular with the ground. An angled door allows for debris to blow up and over the door, or sand to slide off, without blocking it, and the angle also reduces the force necessary to open the door if rubble has piled up on top. Floor area is generally around eight by twelve feet (2.5 × 3. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screen Door
A screen door can refer to a hinged storm door (cold climates) or hinged screen door (warm climates) covering an exterior door, or a screened sliding door used with sliding glass doors. In any case, the screen door incorporates screen mesh to block birds, flying insects or airborne debris such as seeds or leaves from entering, and pets and small children from exiting interior spaces, while allowing for air, light, and views. History The first screen doors were made using cheesecloth. After the American Civil War, wire cloth was coated with paint and sold for window screens. Construction Aluminium framed Aluminium sliding screen doors are generally constructed by two methods: rollformed or extruded. In both cases the rectangular rollformed or extruded shapes are joined together into a door frame using metal corners or screws. Rollformed The first are rollformed from thin aluminium sheets into a rectangular shaped door frame which incorporates a screen channel to hold the windo ...

Vinyl Group
In organic chemistry, a vinyl group (abbr. Vi; IUPAC name: ethenyl group) is a functional group with the formula . It is the ethylene (IUPAC name: ethene) molecule () with one fewer hydrogen atom. The name is also used for any compound containing that group, namely where R is any other group of atoms. An industrially important example is vinyl chloride, precursor to PVC, a plastic commonly known as ''vinyl''. Vinyl is one of the alkenyl functional groups. On a carbon skeleton, sp2-hybridized carbons or positions are often called vinylic. Allyls, acrylates and styrenics contain vinyl groups. (A styrenic crosslinker with two vinyl groups is called '' divinyl benzene''.) Vinyl polymers Vinyl groups can polymerize with the aid of a radical initiator or a catalyst, forming vinyl polymers. Vinyl polymers contain no vinyl groups. Instead they are saturated. The following table gives some examples of vinyl polymers. Reactivity Vinyl derivatives are alkenes. If activated ...
