Understanding Replacement Windows
If you’re currently deciding which type of window is best for your home — new or replacement windows, start by studying the specifics of replacement windows. These windows are designed to be fitted into a pre-existing opening without the need to remove the surrounding exterior. If you want to upgrade your windows without major construction work, this might be a perfect option for you. Keep reading the points below to get a better understanding of replacement windows:
- Manufactured for Existing Openings
The window will be installed into the existing window frame, making replacement windows an ideal choice for households with window frames in good condition.
- Fewer Disruption
The siding, brick, and interior trim will remain untouched during the installation of your replacement window, making the whole process less invasive. This also means installing replacement windows is cheaper.
- Fit for Window Renovations
If you’ve noticed drafts, poor insulation, operation errors, or other malfunctions, replacement windows will help you upgrade your window’s functionality without changing its size or layout.
- Enhanced Energy Efficiency
The majority of modern replacement windows offer such advanced features as triple-pane glass, low-E coatings, and improved sealing, helping you cut energy loss and enhance thermal insulation.
- Wide Range of Design Options
If you choose replacement windows for your home, you’ll get the opportunity to select from a wide range of materials, like vinyl, fiberglass, and composite materials. You can match the replacement window to your existing window perfectly, preserving the original look of your interior.
Summing up, replacement windows provide an efficient and budget-friendly way to enhance your existing windows with minimal disruption. If your existing window frames are in good condition and you’re looking for a time and cost efficient solution, replacement windows may be your perfect choice.
Understanding New Construction Window
To make a relevant comparison of new construction windows vs replacement windows, keep reading a detailed review of new construction windows. This type of window is designed for installation during the construction of a new home or as a part of a major repair project. Below, the Lion-Windows Canada experts collected the key insights about new construction windows to help you understand whether they may be a good match for you.
- Intended for New Buildings/Renovations
New construction windows are typically designed for homes under construction or undergo renovations.

New construction windows have a nailing flange enabling secure attachment to the wall framing. This ensures a tight attachment and top-notch weather resistance.
- Require More Installation Work
Usually, installation of a new window unit starts with the removal of exterior siding, trim, and drywall. Thus, the new window installation process will take longer than the replacement window installation.
- Window Design Flexibility
New construction windows allow you to make versatile customizations, including window size, shape, and placement. If adjusting windows to your interior design is your key priority, new construction windows are your choice.
- Structural Strength
New construction windows are installed directly into the framing, ensuring unmatched structural stability.
All in all, new construction windows are best for new construction projects or homes undergoing complete renovation. Among the key benefits of new construction windows are design flexibility and excellent structural stability.

That’s why new construction windows are usually chosen for homes under construction or renovation. Replacement windows, in their turn, are usually installed when the existing frames are in good condition.
Price
Typically, replacement windows are cheaper than new construction windows. This can be explained by lower labor costs, as the installation process is easier and doesn’t involve structural changes. Though the initial cost of new construction windows is higher, this investment may be worth it if you’re looking to renovate your home.
