Should you buy replacement or new construction windows? Keep reading to find out!
When shopping for windows in Markham for your home, you’ll encounter two main ideas: replacement windows and new-construction windows. Are you wondering what you should choose? Let’s explore where replacement windows and new-construction windows are best utilized.
Deciding Between Replacement and New-Construction Windows
Both replacement and new-construction Markham windows ultimately provide homeowners with the same outcome post-installation: a weatherproof, functional window unit, whether it operates or remains fixed.
The use of new-construction and replacement windows is distinct and specific to the situation. New-construction windows are suitable for projects where a wall is being significantly renovated with stud access or when constructing a new wall. On the other hand, replacement windows are ideal for scenarios where the wall structure remains unchanged and only the existing window requires replacing.
Window Categories
New-Construction Windows:
Designed for new spaces, new-construction windows are typically installed in openings that are free of trim or siding. These windows come equipped with nailing fins or attachment flanges on their exterior, facilitating secure installation. Some models feature removable nailing flanges for added versatility.
Replacement Windows:
As the name suggests, replacement windows are intended to replace existing windows, whether they are original new-construction windows or previous replacements. These windows lack nailing fins or flanges, featuring a smooth side to streamline the installation process.
Availability Insights
New-Construction Windows:
Widely available at most home improvement stores, new-construction windows are readily accessible, though the variety in sizes may be somewhat limited.
Replacement Windows:
Obtaining replacement windows can be a challenge for DIY enthusiasts, with online sources being the primary option. Despite the availability, the process of ordering and installing replacement windows is rarely undertaken as a DIY task.
Application Guidelines
New-Construction Windows:
Ideal for erecting new buildings, undertaking substantial renovations, or fixing severely damaged existing frameworks.
Replacement Windows: Opt for replacement windows when updating an existing window without the need to alter the surrounding structure, provided it remains in satisfactory condition.
Interchangeability
New-Construction Windows:
The scenario in which you might need new-construction windows for a replacement context arises only if the wall and its framework are in poor condition. Such situations require significant reconstruction of the wall.
Performance Attributes
Replacement Windows:
It is uncommon to use replacement windows for new constructions. New-construction windows are specifically designed for integration into new wall systems, making them the preferred choice.
Performance Attributes
New-Construction Windows:
Properly installed new-construction windows offer robust weather protection. The insulated glass window unit (IGU) in these windows matches that of replacement windows in terms of insulation.
Replacement Windows: Similarly, replacement windows ensure a weather-tight seal. However, the lack of nailing fins is considered a drawback in terms of installation ease and stability.
DIY Suitability
New-Construction Windows:
Installing new-construction windows is relatively straightforward, although the associated exterior work can be challenging. Their availability in home improvement stores makes them a popular choice for DIY projects in sheds, auxiliary dwelling units (ADUs), or as part of new constructions within the main living area.
Replacement Windows:
The installation of replacement windows poses a greater challenge for DIY enthusiasts, owing to the need for precise measurements and fit.
Optimal Scenarios for New-Construction Windows
Primarily, opt for new-construction windows during the initial building phase or when extensive renovations are underway. New-construction windows are best suited for:
- Constructing a new home
- Building an addition
- Creating an Accessory Dwelling Unit (ADU) or separate structure
- Repairing a wall with significant damage
- Undertaking a major wall reconstruction for any purpose
Constructing a New Home
For new home construction, new-construction windows are essential, as this scenario does not involve replacing existing windows. New-construction windows are standard for all new homes, offering the necessary stability and insulation from the start.
Adding to Your Home
An addition functions similarly to a new home on a smaller scale, typically requiring new-construction windows. The exception might be when part of an existing wall is integrated into the addition, potentially adjusting the window choice.
Repairing or Replacing a Severely Damaged Window
In cases where a window and its surrounding structure are extensively damaged—possibly due to termites, rot, or other issues—the entire area, including framing, siding, and interior components, might need reconstruction. In such instances, despite the additional carpentry work involved, opting for a new-construction window is often as economical and straightforward as installing a replacement window, but with the added benefits of improved insulation and a more secure, weather-tight seal thanks to the nailing fins.
Ideal Situations for Replacement Windows
Replacement windows are the go-to choice when you’re dealing with an existing structure where the walls need to remain largely undisturbed, aside from the window swap itself. This includes removing the old window and perhaps updating the interior and exterior trim. Replacement windows are most suitable for:
- Directly swapping an old window for a new one
- Utilizing new-construction windows that have removable nailing fins
- Keeping the existing wall structure intact
Replacing an Existing Window
Choosing to install a replacement window in a structurally sound wall minimizes the risk of unnecessary damage and additional work compared to installing a new-construction window. The interconnected nature of windows, walls, trim, and siding means changing one component can affect the others.
The advantage of replacement windows lies in their design, which allows for horizontal installation with minimal disruption to surrounding elements. Although installing replacement windows might necessitate temporary adjustments like removing interior trim, this can often be done in a way that allows for the trim to be reinstalled or replaced with similar ease. Some touch-up painting might be needed once the trim is back in place.
Adapting New-Construction Windows with Removable Fins
The difference between new-construction windows with nailing fins and replacement windows without them raises the question: Can you simply remove the fins from new-construction windows to mimic replacement windows? In certain situations, this is achievable.
Some new-construction windows are manufactured with fins that can be easily removed, enhancing their versatility for different installation scenarios.
However, it’s generally not recommended to remove the fins from windows that weren’t designed with detachable fins in mind. Attempting to do so could risk damaging the window’s integrity or even breaking the glass. Additionally, achieving a smooth finish on the window’s exterior to ensure a snug, weather-tight fit can be challenging.
