Selecting the Right Type of Glass for Your Windows and Doors: What are Your Options?

17 March 2017

Today, aluminium or PVC windows and doors come in a variety of sizes, styles and finishes for commercial and domestic purposes. The thermal performance of these elements is a major concern for property owners, and the type of glass that is in these doors and windows may have a dramatic influence on this performance. In addition, the various options that you have for glass bring other favourable features to these architectural necessities. Explore your options in the following list to learn further details on the various glass options available at present.

1. FGI Clear Float or Annealed Glass

The FGI clear float or annealed glass provides a colourless, distortion-free visual experience with its ability for high-light transmission during daytime hours. When float glass breaks, it produces sharp, jagged shards that are quite dangerous, and on top of this negative, it does not increase the thermal performance of the doors and windows.

2. Tinted Glass

To create this type of glass, manufacturers add metal oxides to clear float glass in a specific manner. Tinted glass reduces heat by absorbing and re-radiating solar energy. For this reason, it increases the thermal performance of windows and doors. However, similar to float glass, it will break into dangerous shards. Common colours for this glass are green, blue, grey and bronze.

3. Low-E Glass

Low emissivity or Low-E glass contains a thin metallic coating on its surface that decreases the emission of thermal radiation by reducing the heat transference through it. Instead of absorbing radiation, it reflects it, and as a result, improves the insulation properties of the doors and windows. Colours in this glass range from clear to blue.

4. Reflective Glass

You receive an efficient level of solar control with this type of glass since its metallic coating is highly reflective beyond that of the standard tinted glass.

5. Toughened Glass

Toughened glass goes through a process that helps to strengthen it to lessen its risk of breaking. On top of this, when a piece of it does break it shatters into small pieces and not large, dangerous shards. Many types of glass such as clear float, Low-E, reflective and tinted varieties can go through this process.

6. Laminated Glass

Manufacturers permanently fuse two or more pieces of glass together using an interlayer of a material such as ethylene-vinyl acetate or polyvinyl butyral using a process that involves pressure and heat to create this type of glass. The interlayer acts as a safety shield since it holds together all the small pieces or shards of glass in the event of breakage and earns this glass the classification of a Grade-A safety glass.
