The glass panes are separated by a "spacer". A spacer, which may be of the warm edge type, is the piece that separates the two panes of glass in an insulating glass system, and seals the gas space between them. The first spacers were made primarily of steel and aluminum, which manufacturers thought provided more durability, and their lower ...
The large panes of glazing in this station are pieces of float glass. The breakthrough in large, mass-produced, continuous glass production happened in the 1950s with the development of the Float glass manufacturing process. Molten glass is poured over a surface of molten tin, where it flattens out and can be drawn off in a ribbon.
The glass floats on the tin, and levels out as it spreads along the bath, giving a smooth face to both sides. The glass cools and slowly solidifies as it travels over the molten tin and leaves the tin bath in a continuous ribbon. The glass is then annealed by cooling in an oven called a lehr. The finished product has near-perfect parallel surfaces.
Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension .
The notion of a greenhouse conjures up visions of everything from something barely larger than a terrarium to an expansive conservatory, like one found in the gardens of Biltmore Estate.
Quadruple glazing (quadruple-pane insulating glazing) is a type of insulated glazing comprising four glass panes, commonly equipped with low emissivity coating and insulating gases in the cavities between the glass panes. Quadruple glazing is a subset of multipane (multilayer) glazing systems.
