Types of Glass Mixtures 1. Silica Glass Mainly containing silica (main ingredient of glass) Weather and temperature resistant 2. Window Glass Mixed with Sodium Oxide (14%) + Lime (10%) Poor heat resistance, easy to form and transparent 3. Pyrex type Glass Main admixture of boric oxide (12%) Low thermal expansion, good for bottles/cookware 4. Crystal Glass Lead Oxide (25%) Very high mixture percentage High refractive index, high elasticity (resonance) 5. Aluminosilicate Glass Alumina (16%) and Magnesia (7%) Fiberglass composition, higher strengths typically mixed with plastics 6. Oxide Glass Alumina (90%) and Oxide (10%) Extremely clear glass, does not contain silica, mainly used for special fibers

Important Variables in Window Glass 1. U-Value U-Value represents the heat loss due to conduction and convection. Low U-Values are preferred for windows as they are the biggest source of heat loss through convection and conduction. 2. Solar Heat Gain Coefficient (SHGC) SHGC is a ratio between 0 and 1 that represents the amount of solar gain. The higher solar gains, the more radiation energy a space gains. This is preferable in winter time and passively heated buildings. 3. Visual Transmittance (VT) Visual Transmittance is another ratio between 0 and 1. This ratio represents the amount of light that is being allowed through the window opening. Notes: With these 3 values, the most important factors of a window are determined. Things such as tint or double glazing are used specifically to change these values.
