2. Glazing (window) - Wikipedia

   en.wikipedia.org/wiki/Glazing_(window)

   Double-paned windows are the norm in new residential installations, as they offer substantial energy savings in comparison to single-paned glass. Each individual glass pane has poor insulation properties, with an R-value (insulation), or measure of an object's resistance to heat conduction, of 0.9. However, when two panes are placed in series ...

3. Insulated glazing - Wikipedia

   en.wikipedia.org/wiki/Insulated_glazing

   A typical installation of insulated glass windows with uPVC frames. Fitting a second pane of glass to improve insulation began in Scotland, Germany, and Switzerland in the 1870s. [2] Insulating glass is an evolution from older technologies known as double-hung windows and storm windows. Traditional double-hung windows used a single pane of ...

4. Tempered glass - Wikipedia

   en.wikipedia.org/wiki/Tempered_glass

   Using tempered glass can pose a security risk in some situations because of the tendency of the glass to shatter completely upon hard impact rather than leaving shards in the window frame. [10] The surface of tempered glass does exhibit surface waves caused by contact with flattening rollers, if it has been formed using this process.

5. Storm window - Wikipedia

   en.wikipedia.org/wiki/Storm_window

   Triple-Track: Consisting of two window panes and a half-screen on three separate tracks, allowing for adjustable ventilation. Two-Track Sliders: Designed for horizontal opening, suitable for slider windows. Basement Storm Windows: Typically a single fixed pane of glass covering the window.

6. Window - Wikipedia

   en.wikipedia.org/wiki/Window

   The panes of glass are separated, creating an insulating air pocket that inhibits heat transfer much better than single pane windows. Double-paned windows have two parallel panes (slabs of glass) with a separation of typically about 1 cm; this space is permanently sealed and filled at the time of manufacture with dry air or other dry ...

   Soda–lime glass (for containers) [2] Borosilicate (low expansion, similar to Pyrex, Duran) Glass wool (for thermal insulation) Special optical glass (similar to Lead crystal) Fused silica Germania glass Germanium selenide glass Chemical composition, wt% 74 SiO 2, 13 Na 2 O, 10.5 CaO, 1.3 Al 2 O 3, 0.3 K 2 O, 0.2 SO 3, 0.2 MgO, 0.01 TiO 2, 0. ...
