Custom Cutting

Our state-of-the-art glass cutting equipment provides precise, quality cuts every time. Because we are a full-service glass fabrication company, we can cut any flat glass product available. we can custom cut common glass items such as windows, mirrors, doors, however, we even have the capabilities to custom cut other types of glass, such as cabinet glass, tabletop glass, shelving, and fireplace glass.


New in 2018, Northwestern Glass Fab began operating a new 84” x 196” high speed tempering oven. This oven is designed to service our glazing, commercial interiors, manufacturing, and store fixture customers. This, along with our existing glass fabrication capabilities means we do everything in our facility, allowing us the flexibility to meet your tight deadlines.

Insulated Units

Insulated glass units consist of two or more panes of glass that are separated using a spacer to create an air space between them. They are then are sealed around the edges to prevent moisture from penetrating that airspace. This glass fabrication technique helps to minimize the transfer of hot or cold air, making it an energy-efficient window option for homes and businesses. Rest assured, all of our insulated glass is IGCC certified and goes through multiple inspections to ensure a quality and effective product.

Edge Polishing

Edge polishing makes glass safer for handling, but it’s real purpose is to add a stylish finish to your glass purchase. Polishing the edges gives glass it’s “finished look” and is used in products such as shelving, glass walls, shower doors etc. See below for many of the different options available from Northwestern Glass Fab. Click on the illustrations to the left to see more. 

  • Flat Polish. Typically the most popular choice of edgework, flat polished edges give you a high polished and glossy appearance, perfect for almost any application. 
  • Pencil Polish. This edge gives you a rounded edge rather than a flat edge. It is a smooth, glossy finish and is a popular style if you are looking for a different look.
  • Beveled Edge. Beveled glass is perfect for an elegant look and are typically used on vanity mirrors, decorative mirrors, or tabletops.
  • Miter. Using similar techniques as flat edge polishing, mitered glass edges are flattened down, however the entire edge of the glass is then mitered at an angle, anywhere from 0° - 45°.
  • Ogee. This look combines a beveled edge with a pencil polish giving it a smooth and "wavy" profile.

Vinyl Backing

Typically used on any style of mirror or safety glass, vinyl backing is the process of attaching an adhesive protective film on the the back of the glass. This is typically used for safety to prevent people from being injured should the glass break.


Sandblasted glass is perfect for any type of glass project for architects, interior designers, retailers, manufacturers, and more. How it works: our sandblasting machines spray a high-pressure abrasive at the glass to roughen its surface. This method of glass design can take any normal piece of glass and give it a fresh appearance while still maintaining natural light. Choose to add frosted logos, shapes, and even images to any glass surface, including glass shower doors, conference room glass walls, glass signs, and more.

Clear Shielding

Hard water creates unsightly and resistant water spots on unprotected glass. The limescale from the hard water etches the surface of glass over time. ClearShield helps resist the build up of limescale and is proven to have hygienic properties. This means cleaner and brighter glass for your shower door and keeps it looking brand new for years to come.

Water Jet Cutting

Water jets are ideal for making high-quality cut outs and holes in glass. Many things like frameless shower doors, mirrors, signs, and countless other architectural applications require glass with these special cut outs and holes. Water jets can cut any shape in any thickness of glass giving you endless possibilities to make your ideas to come to life.
