Your vehicle’s ability to retain roof strength and structure during a rollover accident.
A family of polymers ranging from rubbery to brittle. Usually formed by the reaction of a diisocyanate with a hydroxyl; also called polyurethane. A high strength polyurethane adhesive is the material used to bond the glass to the vehicle's body in today’s automobiles.
The area along the pinchweld where the bead of urethane is applied.
Vehicle Identification Number. This is a 17-digit combination of letters and numbers that’s unique to your vehicle. Your VIN is embossed onto a small plate attached to the dashboard at the bottom left side of your windshield or on the side of the driver's front door.
The manufacturer of the vehicle, such as Ford, Chevrolet, or Dodge.
The type of vehicle, such as Mustang, Sebring or Camry.
The vehicle’s body design, such as 2-door, 4-door, convertible, or SUV.
A proprietary method developed by Portland Glass® to repair breaks before they spread:
- Moisture and contamination is drawn out of the break with our unique ultra-vacuum system
- The void created by the near-perfect vacuum is filled with proprietary clear liquid resin
- The resin is cured with ultra-violet light
- The permanent high-bonding strength of the resin seals cracks and breaks and prevents them from spreading
Low E Glass:
Energy efficient glass that is treated with a coating to effectively block the harmful ultravioloet rays of the sun.
A process to prevent glass brittleness in which glass is heated to a high temperature and then cooled slowly.
Counterbalances the sashes when opening and closing the window.
Glass that has been created with a specific type of polished or shaped edge work. Beveled glass is often used for tabletops, desktops, shelving, and custom built furniture.
The mechanism attached to a door and a door jamb to automatically close the door.

An individual who installs commercial or home improvement glass.
The process and techniques of installing home improvement and commercial glass.
Optional feature used for decoration.
The top part of the window jamb.
High Performance Glass:
A color-coated glass that is used in commercial glazing applications.
Insulated Glass (thermal panes):
Insulated glass is created when two pieces of glass are sealed together with a vacuum. This glass unit increases energy efficiency with affecting viewing quality through the window.
A safety glass that is created by sandwiching a piece of vinyl between two pieces of glass.
Brand name of a polycarbonate sheet that is clear and high impact resistant. It comes with a 3-year warranty against breakage. It is used in commercial and home improvement glazing for its safety, security, and energy savings.
Where the 2 sashes meet and where the lock is found on a window.
NGA:National Glass Association, the largest trade association specifically for the North American glass industry. NGA represents the architectural, automotive and specialty glass segments of the industry.

The operable portion of the window containing the glass.
Protrudes and slopes slightly from the window to help ensure proper rain drainage.
Window with only one sash which opens and closes.
The metal plate that a door centers over when the door is closed. A threshold helps seal the entrance against water and air infiltration.
A measure of how well heat escapes through a window. The lower the U-factor number, the greater the window’s insulating ability.
Ventilation Limit Latch:

What is ENERGY STAR? Energy Star - is the symbol for energy efficient products that help us save money and protect the environment. These energy-efficient products help save on energy bills without sacrificing performance, features, and comfort.
If a material that is less conductive than a conventional aluminum spacer is used at the edge of the glass, it is said to be warm edge. Current warm edge offerings include aluminum with a thermal break, stainless steel, plastic and even foam.
Tempered Glass:Tempered glass is heat –treated safety glass that when broken crumbles into small granular chunks instead of jagged shards. It is used in a wide variety of applications, including auto glass and shower doors.
Will Low-E or argon gas filled glass change the way my window looks?
Yes, Low-E coating adds a slight tint to the glass. Argon has no appearance. We recommend they be used in conjunction with each other.
