Edge strength: crack will form if the tensile strength of glass edge exceeds the critical point. Clean cut glass is the strongest and after that polished edge is strongest. Artificial heating and cooling: if heating or cooling vents are present, the glass can heat or cool excessively and may result in thermal stress.

The 1921-1928 Newport, Kentucky steel strike was a labor dispute between steel workers in Newport, Kentucky and Andrews Steel Co., the owners of the Andrew Steel Plant and Newport Rolling Mill.
Insulated glazing (IG) forms a very compact multi-layer sandwich of air and glass, which eliminates the need for storm windows. Screens may also be left installed year-round with insulated glazing, and they can be installed in a manner that permits installation and removal from inside the building, eliminating the requirement to climb up the ...
The Broken Windows theory is a criminological theory that was first introduced by social scientists James Q. Wilson and George L. Kelling in a 1982 issue of The Atlantic Monthly, in which they argue that areas exhibiting visible evidence of anti-social behaviour such as graffiti and vandalism act as catalysts for the occurrence of more serious crimes.

The blue plastic on the central building is the vapour barrier for the thermal wall insulation before the exterior cladding has been fixed. Building insulation materials are the building materials that form the thermal envelope of a building or otherwise reduce heat transfer.
As it is an opaque material, the remaining 10 percent must be reflected. Conversely, a low-e material such as aluminum foil has a thermal emissivity/absorptance value of 0.03 and as an opaque material, the thermal reflectance value must be 1.0 - 0.03 =0.97, meaning it reflects 97 percent of radiant thermal energy. Low-emissivity building ...
In 1925 the company, who had long exported to the North American market, acquired the International Casement Company, Jamestown, New York that became Hopes Windows Inc., in 1930. Hope's 1930 catalogue. Hope's Gearings, along with their metal glazing systems, were fitted to many major industrial plants such as the Ford Dagenham assembly plant at ...
