A technical textile is a textile product manufactured for non-aesthetic purposes, where function is the primary criterion. [1] Technical textiles include textiles for automotive applications, medical textiles (e.g., implants), geotextiles (reinforcement of embankments), agrotextiles (textiles for crop protection), and protective clothing (e.g., heat and radiation protection for fire fighter ...
A thermal bridge is created when materials create a continuous path across a temperature difference, in which the heat flow is not interrupted by thermal insulation. Common building materials that are poor insulators include glass and metal. A building design may have limited capacity for insulation in some areas of the structure.
The material is sustainable, reusable and recyclable. There are two types of cork, the pure cork, which is preferable due to its natural bonding properties, and the agglomeration cork. The pure cork is made by processes of heating and steaming whereby cork granulates are molded into a block. The natural resin of the cork acts as a bonding agent.
Thermal conductivity depends on the material and for fluids, its temperature and pressure. For comparison purposes, conductivity under standard conditions (20 °C at 1 atm) is commonly used. For some materials, thermal conductivity may also depend upon the direction of heat transfer.
A area of material through which air flows (m 2) L thickness of material through which air flows (m) V' volume flow rate of air (m 3 /h) ΔP pressure difference along the length L of material (Pa) Equation is a simplified form of Darcy's Law. In building applications the air is at ambient pressure and temperature and small changes in the ...
An external wall insulation system (or EWIS) is a thermally insulated, protective, and decorative exterior cladding procedure involving the use of expanded polystyrene, mineral wool, polyurethane foam or phenolic foam, topped off with a reinforced cement based, mineral or synthetic finish and plaster.
Thermal effusivity can also be a measure of a solid or rigid material's thermal inertia. [4] Thermal effusivity is a parameter that emerges upon applying solutions of the heat equation to heat flow through a thin surface-like region. [3] It becomes particularly useful when the region is selected adjacent to a material's actual surface.
A radiant barrier is a type of building material that reflects thermal radiation and reduces heat transfer. Because thermal energy is also transferred by conduction and convection, in addition to radiation, radiant barriers are often supplemented with thermal insulation that slows down heat transfer by conduction or convection.
