building insulation
21R-value (insulation) — The R value or R value is a measure of thermal resistance (K·m²/W) [Oak Ridge National Laboratory, [http://www.ornl.gov/sci/roofs+walls/insulation/ins 02.html Which Kind Of Insulation Is Best?] , retrieved 2008 07 13.] used in the building and… …
22Thermal insulation — The term thermal insulation can refer to materials used to reduce the rate of heat transfer, or the methods and processes used to reduce heat transfer.Heat energy can be transferred by conduction, convection, radiation or when undergoing a phase… …
23Cavity wall insulation — is used to reduce heat loss through a cavity wall by filling the air space with a porous material. This immobilises the air within the cavity (air is still the actual insulator), preventing convection, and can substantially reduce space heating… …
24Dynamic insulation — is a form of insulation where cool outside air flowing through the thermal insulation in the envelope of a building will pick up heat from the insulation fibres. Buildings can be designed to exploit this to reduce the transmission heat loss (U… …
25Wool insulation — is made from sheep wool that is mechanically bonded together to form insulating batts and ropes. Batts are commonly used in timber frame buildings and ropes are primarily used between the logs in log homes. Wool insulation is used for both… …
26Exterior Insulation Finishing System — Exterior Insulation and Finish Systems (EIFS) are a type of building product that provides exterior walls with an insulated finished surface, and waterproofing in an integrated composite material system. Terminology Although often called… …
27Exterior insulation finishing system — Exterior insulation and finishing system (EIFS) is a type of building exterior wall cladding system that provides exterior walls with an insulated finished surface and waterproofing in an integrated composite material system. Contents 1… …
28External wall insulation — system= External wall insulation system (EWIS) a thermally insulated, protective, decorative exterior cladding system which consist of: *foamed polystyrene *mineral wool *polyurethane foam *mineral or synthetic plasterThermal insulation thickness …
29Autonomous building — An autonomous building is a building designed to be operated independently from infrastructural support services such as the electric power grid, municipal water systems, sewage treatment systems, storm drains, communication services, and in some …
30Natural building — A natural building involves a range of building systems and materials that place major emphasis on sustainability. Ways of achieving sustainability through natural building focus on durability and the use of minimally processed, plentiful or… …
