1. Single-pane windows are made with a single layer of glass.  They come in all of the same styles and materials that double-pane  windows do, but they are not as efficient at keeping out noise or  seasonal temperatures. 

2. Thermopane or a double-paned window has two panes of glass, separated by a trapped air space. The trapped air acts as an insulator, reducing heat loss through the glass. A common problem with windows of these types is that you can get fogging inside the window (between the panes of glass) which is indicative of a broken seal.

3. Tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering creates balanced internal stresses which cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards. 

4. Laminated glass is normally used when there is a possibility of human impact or where the glass could fall if shattered. Skylight glazing and automobile windshields typically use laminated glass. 

5. Poly(methyl methacrylate) (PMMA) or as it is better known "Plexiglas" is a transparent thermoplastic, often used as a light or shatter-resistant alternative to glass. It is sometimes called acrylic glass.
