What are New Construction Windows?
New construction windows serve homes under construction, business properties plus any home additions or total remodels. Builders add these windows at the start of construction while they put up walls and frames. These windows must be placed but before they add exterior materials like brick siding or trim. A full window frame plus nail fins on all sides fixes the window straight to the wall. The nail fin or flange also keeps water out along with adds extra stability. A variety of sizes, styles as well as features really lets you match what the space needs.
What are Replacement Windows?
Replacement windows are designed to fit into existing window frames, making them a quicker, less invasive option than new construction windows. The two main types of these windows are full-frame and pocket (insert) replacement. Full-frame replacement involves removing the old frame and installing a new window with an attached frame, while pocket replacement fits a new window into the existing frame.
These windows are available in various styles and materials, offering versatility.
They are smaller than new construction windows and require minimal changes to the surrounding structure. Replacement windows may include nailing fins (full-frame replacement) or not (pocket windows), allowing for flexible installation options.
What’s the Difference Between Replacement Windows vs New Construction Windows
Installation
Replacement windows are installed by removing the old window sashes and fitting the new window directly into the existing frame. Since the original frame remains intact, the installation process is quicker as siding, trim, and walls typically do not need to be removed or rebuilt. This option is ideal for homeowners who wish to replace old windows without modifying the surrounding structure.
New Construction windows require the installation of both the window frame and flange directly into the wall structure, often necessitating the removal of part of the wall for a proper fit. This type of installation is typically performed during the early stages of construction or substantial home renovations. It provides flexibility in placement and size, allowing windows to be added in areas with no windows.
Cost
Replacement windows are less expensive because they don’t need new framing or construction work, thus allowing for faster installation and lower labor costs. The total cost will depend on the material, size, and style of the window, but since no structural changes are necessary, it is less expensive than new construction windows. Usually cost-effective but if the existing frames or sills need repairs, then it could be almost the same cost as new construction windows.
New construction windows are usually pricier than replacement windows since they require additional materials, labor, and sealing to fit into new or remodeled walls. The cost of new construction windows depends on factors such as style, size, material, and features like energy-efficient coatings or custom designs.
Design Flexibility
New construction windows provide maximum design flexibility, allowing homeowners to customize size, shape, and material during the construction phase. For example, homeowners can choose large picture windows for scenic views or select windows that match their home’s architectural style, whether modern, traditional, or contemporary.
Although customizable to a point, replacement windows are still required to fit within a pre-existing frame. This limits homeowners to the shape and size of their old windows, unless they make major structural changes, which is not very common. However, advancement in window technology offers a diversity of styles and materials, as well as materials that replicate older windows. Replacement windows are available in energy-efficient designs, like double-glazed and triple-glazed options, offering better insulation and soundproofing than older single-glazed windows.
Energy Efficiency
These windows can include energy-efficient features like low-E coatings, gas-filled spaces, and insulated frames, helping to prevent heat loss and maintain cooler interiors. Installed as part of the building envelope, they offer superior insulation and greater potential for energy savings. In the new constructions, energy-efficient features like solar shades or automated window treatments are readily incorporated to enhance energy savings.
These windows also offer energy-efficient features, similar to new construction windows. The main difference is that they may not be as airtight if the original frames are damaged. However, with quality materials and proper installation, replacement windows can still deliver significant energy savings. If the existing frames are in good condition, replacement windows can provide similar energy efficiency to new construction windows.
When to Use Replacement Windows?
Replacement windows are an excellent choice for upgrading existing windows without major construction work. They are ideal for home renovations, window upgrades, and budget-friendly projects. If current windows are outdated, damaged, or inefficient, replacement windows can quickly improve both appearance and energy efficiency.
They are also an excellent option for houses where the old window frames are in a good condition since they are faster and cheaper compared to new construction windows. Moreover, replacing old, inefficient windows with energy-efficient models can save on heating and cooling costs in the long run.
When to Use New Construction Windows?
New construction windows are best used for new buildings, major remodeling, changing window locations, and customized homes. These windows are designed to fit seamlessly into the building’s framework, offering maximum design flexibility. If you’re constructing a new home or undertaking large-scale renovations that involve changing the layout, new construction windows can be customized to fit new window openings and provide a smooth finish.
For custom-built homes, these windows allow for complete flexibility to achieve specific architectural styles or unique shapes, making them the best choice when extensive structural changes are required.
DIY vs. Professional Window Installation
DIY Installation
It can be managed for people who have home improvement experience, especially with replacement windows. The key to ensuring that energy efficiency is maintained and leakage does not occur is proper sealing and insulation. DIY can save labor costs, but improper installation can lead to air leaks, water damage, and decreased efficiency. Make sure you have the proper tools, including a drill and caulk gun, if you do it yourself.
Professional Installation
Hiring professionals is recommended for both new construction and replacement windows. They ensure correct installation, especially for new construction windows, which require precise framing and alignment. Professional installers help avoid issues like air leaks, water damage, and improper sealing, and ensure compliance with local building codes. Although professional installation may cost more upfront, it can save money in the long run and is often necessary for warranty coverage.
FAQ’S
What is the difference between a replacement window and a new construction window?
Replacement windows are installed within existing frames, preserving the overall integrity of the building, while new construction windows demand the elimination of the previous frame and require the installation onto the building framework to a more considerable extent.
Are replacement windows costlier than new construction?
Replacement windows are typically more expensive per unit due to added features, but they generally cost less to install. In contrast, new construction windows are cheaper per unit, but installing them in older homes can be more costly and time-consuming due to the need for additional labor and potential damage to the existing structure.
Is it worth replacing 20 year old windows?
Yes, replacing 20-year-old windows can improve energy efficiency, enhance aesthetics, and increase property value. Modern windows offer better insulation, advanced technology, reduced noise levels, and lower maintenance. Over time, the energy savings can offset the initial replacement costs.
How many windows do you lose with replacement windows?
Replacement windows slightly reduce the glass area, especially with a pocket install, where you can lose at least an inch around the glass, and sometimes up to 2-3 inches. However, with a full-frame install, no glass area is lost. While there is some reduction in glass area with replacement windows, the loss is minimal and often outweighed by the benefits.
Conclusion
Choosing between replacement windows vs. new construction windows depends on the specific needs of the homeowner. New construction windows are ideal for new builds or major renovations, offering more design flexibility, while replacement windows are perfect for upgrading existing windows with minimal disruption. Both options provide energy-efficient features, with the decision often influenced by the project scale, budget, and desired aesthetic.
