Why Certified Installations Matter
At Hi-Tech Energy Windows we have spent countless hours to research, design, develop and produce a window and door system that meets the energy saving requirements of our harsh Manitoba climate. These systems must be installed to our standards to achieve their full energy saving benefits.

How a Bay Window is Manufactured
/in Windows /by os-hitechA bay or bow window is more than just a style upgrade; it’s an architectural feature that changes the way a room feels, looks, and performs. Unlike a standard full-frame window, a bay projects outward from the wall, combining multiple window units into one seamless structure.
At Hi-Tech Energy Windows & Doors, we don’t piece together bay windows onsite. Every bay and bow window we install is designed, built, and assembled as a complete unit in our Winnipeg manufacturing facility. That means stronger performance, better insulation, and the confidence of our Lifetime Transferable Warranty , which provides protection that stays with the home, even if you sell it.
Here’s a behind-the-scenes look at how bay windows are constructed in the factory, and why Hi-Tech’s process stands apart.
Step 1: Measuring and Designing the Bay Window
Every bay or bow window starts with an accurate measurement of the existing opening:
These details drive the design, ensuring the final window fits seamlessly into the home.
From here, we determine the number of window faces: a classic three-panel bay (one fixed center, two angled sides) or a four-plus-panel bow with a graceful curve.
Step 2: What Bay Windows Are Made Of
Each face of the bay window is manufactured as an individual box unit. These can be:
Hi-Tech manufactures two different window lines, both designed for Manitoba’s extreme climate. Units are built from maintenance-free PVC and composite materials, ensuring durability with no risk of rot or warping.
Once the box units are built, they’re ready to be joined into the larger frame.
Step 3: How Bay Windows Are Constructed in the Factory
This is where Hi-Tech’s process stands apart. Instead of shipping loose box units to the jobsite, we build a complete bay window system in the factory.
This ensures the bay window leaves the factory as one solid, insulated structure, not a collection of parts.
Step 4: Exterior and Interior Finishes
The finishing details are built into the unit itself:
Trim details are completed in the factory, giving the window a clean, finished look from the day it arrives.
Step 5: Insulation, Energy Efficiency, and Weatherproofing
Are bay windows energy efficient? Yes, when built properly. Hi-Tech bay windows are designed with Manitoba’s climate in mind:
Older bays can be drafty, but Hi-Tech’s factory-built units meet Energy Star® standards, helping reduce heat loss and lower energy bills.
Step 6: Quality Control and Assembly
Every Hi-Tech bay window undergoes a full quality inspection before leaving the factory:
Once approved, the complete unit is packaged and shipped to the home for installation.
Step 7: Installation in the Home
Because the bay arrives as a factory-built product, installation is faster, cleaner, and more reliable:
Unlike onsite assembly, this method avoids inconsistencies, reduces installation time, and ensures the performance of the factory-built system.
Our Lifetime Transferable Warranty: Coverage That Stands Apart
A bay window is a significant investment, and warranties matter. At Hi-Tech Energy Windows & Doors, we back every bay and bow window with our Lifetime Transferable Warranty.
Homeowners need to understand the difference between factory-built, custom-fit full-frame windows and onsite-assembled bay windows. While some companies may assemble bays from individual box units on the jobsite, not all components may be covered the same way. Asking the right questions about what is covered under product warranty vs. install warranty is critical.
Why Hi-Tech’s Bay Windows Are Different

Don’t settle for a window that’s pieced together onsite. Choose Hi-Tech, and get the confidence of a factory-built product backed by Manitoba’s only Lifetime Transferable Warranty.
