Flat Glass (single-pane)
Featuring a single layer of glass available in an assortment of thicknesses and styles, flat glass is less noise tolerant and temperature resistant than insulated glass.
Insulated Glass (double-pane and triple-pane)
Consisting of two (double) or three (triple) sheets of glass, insulated glass excels at reducing noise and assisting in temperature control. Metal edge spacers seal gaps between panes to ensure the enclosed air space remains moisture-free.
Using a unique, slow-paced cooling process, annealed glass is better adapted for resisting rapid temperature changes, resulting in less cracking.
Safety Glass-Fully Tempered*
Fully tempered glass undergoes a specialized treatment process using heat and chemicals to significantly increase its strength. When compared with a panel of annealed glass of similar thickness and dimension, fully tempered glass proves four times stronger. If broken, this glass shatters into countless minuscule pieces, causing less chance of injury by cut, making it a safer choice than some of its rivals.
Laminated glass consists of two or more layers permanently fused together using an advanced polymer inter layering method. When shattered, laminated glass tends to hold together, bonded by its interlayer that fuses multiple panes together.
*Safety glass, including fully tempered and laminated variations, is installed for patio doors, French doors, entry doors, sidelights, skylights and windows above tubs and showers. In addition, windows that are either fixed or operable require tempered glass if all four of the following criteria are met: glass panel measures 9 square feet; the bottom edge of the glass is less than 18 inches above the floor surface, the top edge of the glass exceeds 36 inches from the floor surface; a walkable surface is fixed within 36 inches of the glass.
A microscopic coating of metallic oxides allows Low-E glass to resist the penetration of UV rays and infrared light without blocking natural light. By significantly limiting the amount of UV and infrared light passing through, Low-E glass is capable of reducing energy waste by better maintaining internal building temperature. This additional assistance in keeping your home warm in the winter and cool in the summer adds to your home’s overall energy efficiency.
Commonly used for economical single-pane and double-pane replacement, clear glass is free from Low-E treatments.
As the name suggests, privacy glass provides extra privacy for the home by means of frosted or textured panes that blur vision. Varying degrees of visibility are available, and privacy glass typically allows for sufficient natural light to pass through. Privacy glass is often used in bathroom and basement windows.
