Acoustiblok
Acoustiblok, a registered trademark product of Acoustiblok Inc, is manufactured in the United states. It is a sound attenuation material that was introduced in 1999. It is implemented in new construction or remodeling projects. It is also designed for application beneath the drywall and other finishing materials. Physical properties Acoustiblok is a mass-loaded vinyl, sound isolation product. It is an extremely dense but very flexible material that comes in two sizes; 16oz. and 32oz. * Sixteen ounce Acoustiblok is 1/8" thick, and weighs 1 lb/ft2. * Thirty-two ounce Acoustiblok is 1/4" thick, and weighs 2 lb/ft2. * Barium Free * Color: Black * High UV Resistance * No Fungal or Algal Growth Performance data The ability of a partition to block transmission of airborne sound is typically described by a single number rating of the Sound Transmission Class (STC). * Sixteen ounce Acoustiblok material has an STC of 26. * Thirty-two ounce Acoustiblok material has an STC ...

Registered Trademark
The registered trademark symbol, , is a typographic symbol that provides notice that the preceding word or symbol is a trademark or service mark that has been registered with a national trademark office. A trademark is a symbol, word, or words legally registered or established by use as representing a company, product or service.For example, Unregistered trademarks can instead be marked with the trademark symbol, , while unregistered service marks are marked with the service mark symbol, . The proper manner to display these symbols is immediately following the mark; the symbol is commonly in superscript style, but that is not legally required. In many jurisdictions, only registered trademarks confer easily defended legal rights. In the US, the registered trademark symbol was originally introduced in the Trademark Act of 1946. Because the symbol is not commonly available on typewriters (or ASCII), it was common to approximate it with the characters (or ). An example of a ...

Sound Attenuation
A sound attenuator, or duct silencer, sound trap, or muffler, is a noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces. In its simplest form, a sound attenuator consists of a baffle within the ductwork. These baffles often contain sound-absorbing materials. The physical dimensions and baffle configuration of sound attenuators are selected to attenuate a specific range of frequencies. Unlike conventional internally-lined ductwork, which is only effective at attenuating mid- and high-frequency noise, sound attenuators can achieve broader band attenuation in relatively short lengths. Certain types of sound attenuators are essentially a Helmholtz resonator used as a passive noise-control device. Configuration Generally, sound attenuators consist of the following elements: * An inner perfora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drywall
Drywall (also called plasterboard, dry lining, wallboard, sheet rock, gypsum board, buster board, custard board, and gypsum panel) is a panel made of calcium sulfate dihydrate (gypsum), with or without additives, typically extruded between thick sheets of facer and backer paper, used in the construction of interior walls and ceilings. The plaster is mixed with fiber (typically paper, glass wool, or a combination of these materials); plasticizer, foaming agent; and additives that can reduce mildew, flammability, and water absorption. In the middle of the 20th century, drywall construction became prevalent in North America as a time- and labor-saving alternative to lath and plaster. History The first plasterboard plant in the UK was opened in 1888 in Rochester, Kent. Sackett Board was invented in 1894 by Augustine Sackett and Fred Kane, graduates of Rensselaer Polytechnic Institute. It was made by layering plaster within four plies of wool felt paper. Sheets were thick wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vinyl
Vinyl may refer to: Chemistry * Polyvinyl chloride (PVC), a particular vinyl polymer * Vinyl cation, a type of carbocation * Vinyl group, a broad class of organic molecules in chemistry * Vinyl polymer, a group of polymers derived from vinyl monomers Materials * PVC clothing, a fabric * Vinyl composition tile, a type of floor tiling * Vinyl siding, an exterior building cladding Music * LP Records The LP (from "long playing" or "long play") is an analog sound storage medium, a phonograph record format characterized by: a speed of rpm; a 12- or 10-inch (30- or 25-cm) diameter; use of the "microgroove" groove specification; and ..., commonly referred to as "vinyl" because they are made with PVC, a co-polymer of vinyl chloride acetate. * ''Vinyl'' (Dramarama album), 1991 * ''Vinyl'' (William Michael Morgan album), 2016 * ''Vinyl'' (EP), by Dramarama * Vinyl Solution, a record label * " Vinyl", a song by Kira Kosarin Film * ''Vinyl'' (1965 film), directed ...

Sound Transmission Class
Sound Transmission Class (or STC) is an integer rating of how well a building partition attenuates airborne sound. In the US, it is widely used to rate interior partitions, ceilings, floors, doors, windows and exterior wall configurations. Outside the US, the ISO Sound Reduction Index (SRI) is used. The STC rating very roughly reflects the decibel reduction of noise that a partition can provide. The STC is useful for evaluating annoyance due to speech sounds, but not music or machinery noise as these sources contain more low frequency energy than speech. There are many ways to improve the sound transmission class of a partition, though the two most basic principles are adding mass and increasing the overall thickness. In general, the sound transmission class of a double wythe wall (e.g. two 4"-thick block walls separated by a 2" airspace) is greater than a single wall of equivalent mass (e.g. homogeneous 8" block wall). Definition The STC or sound transmission class is a sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metal
A metal (from Greek μέταλλον ''métallon'', "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the ''metallic bond'' between the atoms or molecules of the metal. A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. In physics, a metal is generally regarded as any substance capable of conducting electricity at a temperature of absolute zero. Many elements and compounds that are not normally classified as metals become metallic under high pressures. For example, the nonmetal iodine gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure. Equally, some materials regarded as metals c ...

Wall Stud
A wall stud is a vertical repetitive framing member in a building's wall of smaller cross section than a post. It is a fundamental element in frame building. Etymology ''Stud'' is an ancient word related to similar words in Old English, Old Norse, Middle High German, and Old Teutonic generally meaning ''prop'' or ''support''."Stud". def. 1. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) © Oxford University Press 2009 Other historical words with similar meaning are ''quarter'' and '' scantling'' (one sense meaning a smaller timber, not necessarily the same use). ''Stick'' is a colloquial term for both framing lumber (timber) and a "timber tree" (a tree trunk good for using as lumber (timber)); thus, the names ''"stick and platform"'', ''"stick and frame"'', ''"stick and box"'', or simply ''stick framing''. The stud height usually determines the ceiling height, thus sayings like: "...These rooms were usually high in stud..." Purpose Studs form walls and may carr ...
