R value
| Construction glossary |
A measure of insulation. a measure of a materials resistance to the passage of heat. the higher the r value, the more insulating "power" it has. for example, typical new home's walls are usually insulated with 4" of batt insulation with an

Value added distributor, английский
Value added network - van, английский
A data network operated in the u.s. by a firm which obtains basic transmission facilities from the common carriers, and adds value such as error detection and sharing and resells the service to users. telenet and tymnet are examples of vans.
Value added network services, английский
Value added tax, английский
Налог на добавленную стоимость
Value added tax (vat), английский
Specific type of turnover tax levied at each stage in the production and distribution process. although vat ultimately bears on individual consumption of goods or services, liability for vat is on the supplier of goods or services. vat normally utilizes a system of tax credits to place the ultimate and real burden of the tax on the final consumer and to relieve the intermediaries of any final tax cost.
Value additivity principal, английский
When the value of a whole group of assets exactly equals the sum of the values of the individual assets that make up the group of assets. or, the principle that the net present value of a set of independent projects is just the sum of the net present values of the individual projects.

Value at risk (var), английский
Value axis, английский
A chart axis that displays scaled numerical values.
Value broker, английский
A discount broker whose rates are a percentage of the dollar value of each transaction.
Value chain, английский
- Model of how businesses create value
- Model of how businesses create value model of how businesses receive raw materials, add value to the raw materials, and sell finished products to customers
Value chain analysis, английский
Value change, английский
Insulation, английский
- Material which offers extremely high resistance to the passage of current.
- Any material high in resistance to heat transmission that, when placed in the walls, ceiling, or floors of a structure, and will reduce the rate of heat flow.
- Any material that slows down the transfer of heat.
- Any material that reduces the speed of heat transfer
- Изоляция
- A material having high resistance to the flow of electric current. often called a dielectric.
- Изоляция; материал, используемый для изоляции холодильника (морозильника, термоконтейнера и т.п.) integrated disease surveillance (ids)
- Изоляция; материал, используемый для изоляции холодильника (морозильника, термоконтейнера и т.п.)
- Изоляция; изоляционный материал
- A material used to prevent the flow of heat into or out of a building. often consists of ‘batts’ placed in the ceilings and walls, but can also be metal foil or ‘loose fill’ materials, such as recycled paper fluff.
- A material used to prevent the flow of electricity. normally used on electrical wires to prevent electric shock. typical materials used include plastics such as pvc and polypropylene, as well as ceramics and minerals such as mica.
Resistance, английский
- Property of a conductor that opposed the current flow produced by a given difference of potential. the ohm is the practical unit of resistance.
- Уровень сопротивления - уровень цен, при котором активные продажи могут приостановить или развернуть тенденцию к повышению;
- Сопротивление (параметр)
- Сопротивление
- Сопротивление, т. е. уровень цен, при котором активные продажи могут приостановить или развернуть тенденцию к повышению.
- 1. the ability of a person not to get a disease 2. the ability of bacteria or a virus to remain unaffected by a drug the bacteria have developed a resistance to certain antibiotics. 3. opposition to a force
- Resistencia
- Устойчивость; резистентность resource for child health (reach)
- Устойчивость; резистентность
- The property of opposing movement, for example [1] electrical conductors offer resistance to the flow of electricity and dissipate some of its energy, usually as heat. [2] water resists the movement of vessels or other objects by parasitic drag, consuming some of the power available to drive the vessel forward.
- Imperviousness of the coating to mechanical, chemical, physical or weather influences
- Capacity of a member or component, or a cross-section of a member or component of a structure, to withstand actions without mechanical failure e.g. bending resistance, buckling resistance, tension resistance
- A material’s ability to restrict the flow of electrical current through itself. measured in ohms.
- The opposition of a circuit to the flow of current . resistance is measured in ohms, and can be calculated by dividing the voltage by current.
- The ability to impede (resist) the flow of electric current. with the exception of superconductors, all substances have a greater or lesser degree of resistance. substances with very low resistance, such as metals, conduct electricity well and are called conductors. substances with very high resistance, such as glass and rubber, conduct electricity poorly and are called nonconductors or insulators.
- An effective upper bound on prices achieved because of many willing sellers at that price level.
- Capacity of a component, or cross section of a component of a structure to
- The opposition to the flow of an electrical current through a conductor or circuit that does not include inductive or capacitive elements. it can be expressed as the ratio of the applied voltage to the current.
- Resistance is the opposition to the flow of an electrical current through a conductor. its unit is the ohm.

Heat pump, английский
- A mechanical device which uses compression and decompression of gas to heat and/or cool a house.
- A unit that both cools and heats your home. it works just like an air conditioner in cooling mode; however, in heating mode, the refrigerant flow is reversed and heat is extracted from the outside air too heat your home. a heat pump system can be either a
- An air conditioner with a valve that permits alternate heating and cooling
- A device that transfers heat from a cooler reservoir to a hotter reservoir by means of a heat exchanger, requiring the expenditure of mechanical energy in the process; used in an air conditioner whose cooling cycle can be reversed so that it can function as a heater.
- Installation that transfers heat from a colder to a hotter place, opposite to the natural direction of heat fl ows (see energy transfer). technically similar to a refrigerator, heat pumps are used to extract heat from ambient environments like the ground (geothermal or ground source), water or air. heat pumps can be inverted to provide cooling in summer. human development index (hdi): the hdi allows the assessment of countries’ progress regarding social and economic development as a
R factor or value, английский
A measure of a materials resistance to the passage of heat. new homewalls are usually insulated with 4" of batt insulation with an r value of r-13, and a ceiling insulation of r-30.
