Hexabromocyclododecane (HBCD, C12H18Br6) is the most widely used of the cycloaliphatic BFRs. In 1999, the global demand for HBCD (~16 kilotons) was more than double that of the penta-bromodiphenyl ether (~8.5 kilotons) mixture [1]. HBCD is used as thermal insulation in the building industry, and is the principal flame retardant in extruded (XEPS) and expanded (EPS) polystyrene foams [2]. Second...

Computer simulations are used to assess the impact of thermal insulation on transfer heat and moisture in exterior walls residential buildings. The effects internal external a room terraced family house compared using COMSOL Multiphysics software package, evaluating influence placement expanded polystyrene distribution wall while monitoring indoor air temperature during heating cooling regimes....

Four reduced-height (5 m) BS 8414-1 façade flammability tests were conducted, three having mineral-filled aluminium composite material (ACM-A2) with polyisocyanurate (PIR) and phenolic (PF) foam stone wool (SW) insulation, the fourth polyethylene-filled ACM (ACM-PE) PIR insulation. Each was constructed from a commercial engineer’s design, built by practising installers. The ACM-PE/PIR burnt so ...

For a Czochralski growth of Ge crystal, thermal fields have been analysed numerically using the three-dimensional finite volume method (FLUENT package). The arrangement used in a real Czochralski crystal growth lab included a graphite crucible, heat shield, heating device, thermal insulation and chamber including two gas outlets. We have considered two cases for calculations, which are configur...

daylight in classrooms is a critical factor in school design, in terms of its impact on students’ health, learning and visual performance. providing adequate amount of evenly distributed daylight and glare prevention are important challenges in classroom design. window configuration significantly affects the intensity and uniformity of daylight. this paper aims to investigate the effect of wind...
