Vinyl windows are constructed through a detailed process that directly affects how well they perform in terms of energy efficiency, durability and comfort. When done properly, this process results in windows that reduce drafts, improve comfort and help lower energy costs over time.
At a glance, the window manufacturing process includes:
- Custom measurements for a precise fit
- Vinyl frames cut and welded for strength and airtight seals
- Insulated glass with Low-E coatings for better efficiency
- Reinforcements and hardware for smooth, reliable operation
- Final inspections to ensure long-term performance
When was the last time you thought about how your windows were made? Likely, it was when you last had a problem or when you were picking out replacement windows. Although it likely doesn’t cross your mind often, the way your windows are engineered affects your everyday comfort and your home’s energy efficiency. To better appreciate how much work they do, let’s explore the manufacturing process for Window World windows.
What Goes Into Making High-Performance Vinyl Windows?
How your products are made determines how well they perform. It’s why we make our products here in the USA with industry-leading technology. The result is quality windows that look beautiful and last for decades.
Step One: Precision Design
During your free estimate appointment, you’ll choose the window styles you prefer. Our window expert will then measure your current windows, ensuring you get fully custom products that fit your space perfectly. Once you’ve committed to replacement windows from Window World, we’ll send those measurements off to our factory.
Our factory technicians take those measurements and start the manufacturing process by designing and testing the frames. Once the design is set, tested and put through quality assurance inspections, it’s time to start making the frame.
Step Two: Frame Cutting and Welding
Vinyl extrusions, made by melting a mix of carefully controlled materials, form the base of our window designs. Once cooled into shape, the pieces, called profiles, are cut with precision to match the dimensions needed to fit seamlessly into your home’s window frame. It takes real skill and qualifications to make these materials, and we’re grateful to have incredible manufacturing expertise on our side.
These pieces are taken and welded into the correct shape for your home, again with incredible precision. Once completed, the vinyl frame and sash are ready for the other components that will make up the window.
Step Three: Glass Unit Installation
Glass panes are fitted and secured into the frame using sealants made to last. This can be one large pane of glass, as with casement windows, or a series of glass panes as you’d see on double-hung windows.
Low-E, or low-emissivity, glass has its own set of specialized requirements needed to create it before it is installed into the frame. It features a thin, completely transparent coating that reflects infrared heat, promoting year-round indoor comfort, higher home energy efficiency and lower utility costs.
Step Four: Window Assembly and Sealing
From here, the other components of the window are added. We reinforce the windows with metal rails for superior strength and durability, and add other features like our constant-force coil balance system to simplify operations and keep the sash from drifting.
Each window is also equipped with multiple safety features during this part of the process. These include things like dual-opposing locks, interlocking sashes and push-button vent latches made to allow ventilation without sacrificing security.
Step Five: Quality Control and Testing
Throughout the process of creating custom windows, our team conducts rigorous inspections for quality control. When the window is complete, we follow up with another round of quality assurance testing to make sure the window is safe, durable and ready for installation.
All parts of the window are labeled, cleaned and thoroughly inspected before they receive the final sign-off for delivery to your home.
Why the Manufacturing Process Matters for Your Home
When windows are made with attention to detail and care at every step, you can expect high performance and even cost savings for your home.
- Lower energy bills: Energy-efficient windows contribute to lower monthly utility bills, helping your HVAC system work more efficiently due to less heat loss.
- Improved comfort: Your family enjoys a more comfortable home, with no chilly drafts or heat intrusion due to ineffective seals on old windows.
- Consistent, lasting quality: When your windows are made with precision, you’ll enjoy high-performance windows for decades.
