Window Replacement is a popular home renovation project that offers great benefits such as energy savings. The best window brands offer many style and material options, installation options, and strong warranties for homeowners to choose from.
Choosing the right type of window depends on your budget and the overall look of your home.
Frame
A window frame is a collection of studs within a wall system that supports the window. Support comes from below (sill plate and short support studs), on the sides (jack studs and king studs) and above (the header).
Wood frames offer a natural, warm look and can be refreshed with a coat of paint. They are also excellent insulators. However, they require regular sealing and staining. Wood frames are also prone to cracking, which can let in untreated air and water.
Composite frames combine wood, fiberglass, or aluminum materials. They resist moisture, are more resistant to fading from sunlight and can be made to match the style of historic windows. They are also a good choice for energy efficiency. However, they are not as durable or weather-resistant as wood or vinyl frames. The National Fenestration Rating Council label is a helpful tool to help you compare the performance of different frames. This allows you to determine which frames are the best fit for your home.
Glass
The glass in a window provides light, views and insulation. Some glass options include decorative etchings and grids, which can add beauty and style to your home. Some glass is insulated with low-emissivity (low-E) coating, which reduces energy consumption by controlling the transfer of heat within the glazed window.
A window should be replaced if the frame is rotted, which can compromise the safety and integrity of the structure of your home. In addition, if the windows do not open or close easily, moisture and cold air can enter your home, robbing it of its energy efficiency.
When installing a new window, the installer will need to prep the opening by removing the old window and all of its supporting materials. The contractor will then use a hammer and flat bar to begin removing the flashing, trim, brick molding and window itself. Once these materials are removed the installer can install the new window. Many manufacturers offer window installation by their own professionals, which is more expensive than a third-party contractor but may include warranties that cover performance and aesthetic defects.
Hardware
Whether you’re replacing one window or adding new ones to your home, you may need replacement hardware like levers, handles and locks. You can find them along with screens and other truth windows parts here.
Removing an existing window requires a good amount of demolition work, so be prepared to use a hammer and flat bar to pry out trim, brick molding and the old window frame itself (Images 1 & 2). You will need to keep careful track of any pieces you want to preserve for your new replacement windows.
When buying replacement windows, consider the architectural style of your home and choose a shape that will complement it. Also think about any security concerns you have, and make sure your replacement windows meet building codes as far as egress and tempering are concerned. Historic buildings require special consideration, and substitute materials should only be used in cases that are justified by their visual impact.
Insulation
If a window isn’t properly sealed or insulated, it will allow cold air to enter and hot air to escape. This can result in high energy bills.
One solution is to use a window insulation kit that includes self-adhesive weather stripping. This is easy to install and works well in most cases. Another option is caulking, which is inexpensive and quick to apply but needs reapplying periodically.
If the gap around the frame is large, consider using a spray can of expandable foam. A long nozzle on the can helps you reach difficult spots. Use caution when applying the foam because it can quickly fill gaps and may swell up behind drywall or brick molding. It’s also important to remember that running screws through the frame of the window will diminish its effectiveness and could void any warranties. For this reason, shims are typically used to ensure the window is centered in its opening and doesn’t rub against the wall framing.
