A Tour through the Latest Techniques Local Window Manufacturers Employ

A quality-built window is not something you can get from every window manufacturer, and oftentimes the quality of your home or business’ windows could leave you out in the cold and dealing with a burdensome heating bill. What goes into the making of the energy-efficient windows carried by local retailers, and how does it make a difference for you?


Window manufacturers will often have multi-purpose plants to facilitate the entire window-making process, as this allows them to quickly and safely move from the beginning to end stages of the process while minimizing any large changes in venue. They will also consist of several teams specializing in certain aspects of the process, such as glass formation, sealing, and boxing. These teams work in harmony to efficiently produce the highest-quality windows your money can buy.

Cutting, Washing, & Spacing

Glass is fitted with special low-emissivity coatings, and then cut into precisely measured panes by specialized equipment, and each glass pane goes through a thorough washing process to remove any dirt and particles that may be attached to it.  After the glass has been washed, the first pane will be fitted with a spacer and then attached to a second pane of glass, and in some cases a third. Window manufacturers will also imprint a serial code onto the glass so it can be easily identified in later processes.

Presser & Sealer

The panes of glass, separated by spacers, will then be moved into a presser, where they will be sealed together. Argon is then pumped into the spacer to insulate the window from the heat and cold. Because argon is inert, it creates a barrier against thermal transfer. Afterwards, a sealer is mechanically applied to ensure that no gaps or spaces are left in the sealed unit.

Boxing the Window & Installing Hardware

The window manufacturer sends the sealed unit is then sent to be fitted with a box (or buggy), which is assembled to the exact specifications for the window unit. Once the box and window have been combined, the hardware for the window can be installed, such as the springs in a double-hung window or the hand-crank in a casement or awning window.

Putting It All Together

After combining all of the individual parts, a thorough quality assurance check is performed. Upon passing inspection, an assembled window unit is now ready to be sent to the showroom floor of a local window retailer, where it may be selected for installation in a home or business.

Understanding what goes into producing the highest-quality energy-efficient windows is a big step towards choosing the brands that are right for you. Look for those retailers who carry products by window manufacturers who employ the latest techniques, and your home or business will be all the better for it.
