When undertaking window replacement projects, homeowners and managers are often faced with a variety of options, including diverse types of windows tailored to specific needs and budgets. Two common categories are replacement windows and new construction windows.

While they may seem similar, understanding their differences, advantages, and disadvantages is crucial for making an informed decision that aligns with your property’s requirements and long-term goals.

What Are Replacement Windows?

Replacement windows are designed to fit into existing window openings without disturbing the surrounding structure. They are typically installed within the existing window frame, often by removing the old sash and sash stops, leaving the existing exterior and interior trim intact.

Key Features:

• Custom-made to fit the current window opening
• Usually installed from inside the building
• Designed to retrofit existing windows with minimal structural disturbance
• Available in standard sizes but can be custom ordered

What Are New Construction Windows?

Construction windows are designed for installation during new builds when the studs or sheathing is still exposed or major renovations where the existing window frame is to be replaced entirely. They are installed by removing the entire window assembly, including the frame, surrounding trim and siding and attaching the new window directly to the structural framing.

Key Features:

• Designed with nailing fins or flanges for easy attachment to the building’s framing and helps with waterproofing
• Typically used in new construction projects or gut renovations
• Allow for a more comprehensive installation process that replaces the entire window unit

Conclusion

Choosing between replacement and construction windows hinges on multiple factors including structural condition, aesthetic preferences, budget, and project scope.
