Termite Barrier
Termite barriers are materials that have been specifically designed to prevent subterranean termites from gaining access to a structure. Physical termite barriers are free of pesticides and physically block termite foraging activity. Development of physical barriers to effectively exclude subterranean termites makes it possible to design and build structures with a far lower possibility of termite invasion and damage over the life of the building. Because of their small size ( long), impressive reproductive capability (a termite queen products one egg every 3 seconds, or over 10 million eggs per year), and ability to eat through many construction materials, termites are the most destructive of all insects. Termite shields, an early physical barrier, are sheet metal fabrications used for decades in light frame construction. Termite shields are often applied underneath wood sill plates. They are designed to force termites to build their mud tubes outside of the structure, where they ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Termite
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood eating cockroaches of the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...

Foraging
Foraging is searching for wild food resources. It affects an animal's Fitness (biology), fitness because it plays an important role in an animal's ability to survive and reproduce. Optimal foraging theory, Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives. Behavioral ecologists use economic models and categories to understand foraging; many of these models are a type of optimal model. Thus foraging theory is discussed in terms of optimizing a payoff from a foraging decision. The payoff for many of these models is the amount of energy an animal receives per unit time, more specifically, the highest ratio of energetic gain to cost while foraging. Foraging theory predicts that the decisions that maximize energy per unit time and thus deliver the highest payoff will be selected for and persist. Key words used to describe foraging behavior include ''resources'', the elements necessary fo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Formosan Subterranean Termite
The Formosan termite (''Coptotermes formosanus'') is a species of termite local to southern China and introduced to Taiwan (formerly known as Formosa, where it gets its name), Japan, South Africa, Sri Lanka, Hawaii, and the continental United States. The Formosan termite is often nicknamed the super-termite because of its destructive habits due to the large size of its colonies and its ability to consume wood at a rapid rate. Populations of these termites have become large enough to appear on New Orleans' weather radars. A mature Formosan colony can consume as much as 13 ounces of wood a day (about 400 g) and can severely damage a structure in as little as three months. Formosan termites infest a wide variety of structures (including boats and high-rise condominiums) and can damage trees. In the United States, along with another species, ''Coptotermes gestroi'', introduced from Southeast Asia, they are responsible for tremendous damage to property resulting in large treatment ...

Termite Shield
A termite shield is a sheet metal fabrication used in light frame construction to reduce the movement of termites from the soil into wood framing members such as floor joists and studs. Although there are several types of non chemical termite barriers now in use, termite shields are the original. Materials Termite shields can be made up of various materials. One type of termite shield is made from various sheet metals including galvanized steel, terne, copper, or aluminum. The metal is formed to fit between the top of the foundation wall and the bottom of the wood sill plate. The edges of the termite shield are typically hemmed, extended slightly beyond the face of the wall, and turned down to form a drip edge which diverts water running down the face of the wall and reduce the movement of subterranean termites from the soil up into the wood framing members. Termite shields will not protect a building from termite activity, but help make termite activity more visible. Lately, ...

Discussion The building envelope (or the more modern term, building enclosure) is all of the elements of the outer shell that maintain a dry, heated, or cooled indoor environment and facilitate its climate control. Building envelope design is a specialized area of architectural and engineering practice that draws from all areas of building science and indoor climate control. The many functions of the building envelope can be separated into three categories:Straube, J.F., Burnett, E.F.P. ''Building Science for Building Enclosures''.

Waterproofing
Waterproofing is the process of making an object or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths. ''Water-resistant'' and ''waterproof'' often refer to resistance to penetration of water in its liquid state and possibly under pressure, whereas '' damp proof'' refers to resistance to humidity or dampness. Permeation of water vapour through a material or structure is reported as a moisture vapor transmission rate (MVTR). The hulls of boats and ships were once waterproofed by applying tar or pitch. Modern items may be waterproofed by applying water-repellent coatings or by sealing seams with gaskets or o-rings. Waterproofing is used in reference to building structures (such as basements, decks, or wet areas), watercraft, canvas, clothing (raincoats or waders), electronic devices and paper packa ...

Air Barrier
Air barriers control air leakage into and out of the building envelope. Air barrier products may take several forms: *Mechanically-attached membranes, also known as housewraps, usually a polyethylene-fiber or spun-bonded polyolefin, such as Tyvek is a generally accepted moisture barrier and an air barrier (ASTM E2178). *Self-adhered membranes, which are typically also a water-resistant barrier and a vapor barrier *Fluid-applied membranes, such as heavy-bodied paints or coatings including polymeric based and asphaltic based materials *Closed-cell medium density spray-applied polyurethane foam, which typically provides insulation as well *Some open-cell spray-applied polyurethane foam that are of high density *Boardstock, which includes 12 mm plywood or OSB, 25 mm extruded polystyrene, etc. Air barriers are divided into air barrier materials, air barrier accessories, air barrier components, air barrier assemblies and air barrier systems.

Vapor Barrier
A vapor barrier (or vapour barrier) is any material used for damp proofing, typically a plastic or foil sheet, that resists diffusion of moisture through the wall, floor, ceiling, or roof assemblies of buildings and of packaging to prevent interstitial condensation. Technically, many of these materials are only vapor retarders as they have varying degrees of permeability. Materials have a moisture vapor transmission rate (MVTR) that is established by standard test methods. One common set of units is g/m2·day or g/100in2·day. Permeability can be reported in perms, a measure of the rate of transfer of water vapor through a material (1.0 US perm = 1.0 grain/square-foot·hour·inch of mercury ≈ 57 SI perm = 57 ng/s·m2·Pa). American building codes have classified vapor retarders as having a water vapor permeance of 1 perm or less when tested in accordance with the ASTM E96 desiccant, or dry cup method. Vapor-retarding materials are generally ca ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Insulated Concrete Forms
Insulating concrete form or insulated concrete form (ICF) is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs. The forms are interlocking modular units that are dry-stacked (without mortar) and filled with concrete. The units lock together somewhat like Lego bricks and create a form for the structural walls or floors of a building. ICF construction has become commonplace for both low rise commercial and high performance residential construction as more stringent energy efficiency and natural disaster resistant building codes are adopted. Development The first expanded polystyrene ICF Wall forms were developed in the late 1960s with the expiration of the original patent and the advent of modern foam plastics by BASF. Canadian contractor Werner Gregori filed the first patent for a foam concrete form in 1966 with a block "measuring 16 inches high ...

Elastomeric
An elastomer is a polymer with viscoelasticity (i.e. both viscosity and elasticity) and with weak intermolecular forces, generally low Young's modulus and high failure strain compared with other materials. The term, a portmanteau of ''elastic polymer'', is often used interchangeably with rubber, although the latter is preferred when referring to vulcanisates. Each of the monomers which link to form the polymer is usually a compound of several elements among carbon, hydrogen, oxygen and silicon. Elastomers are amorphous polymers maintained above their glass transition temperature, so that considerable molecular reconformation is feasible without breaking of covalent bonds. At ambient temperatures, such rubbers are thus relatively compliant ( E ≈ 3 M Pa) and deformable. Their primary uses are for seals, adhesives and molded flexible parts. Application areas for different types of rubber are manifold and cover segments as diverse as tires, soles for shoes, and damping and ...
