The Difference Between Full Frame and Insert Window Replacement

Window replacement for a client's home by Kelly Window & Door.

There are two primary ways replacement or new construction windows are installed: full frame or inserts. The method that’s best for your home depends on several factors such as the condition of your window frames, your desired outcome, and budget. Also, the number of years you plan to live in your home should also be taken into consideration when deciding between full frame replacement windows or insert replacement windows. 

Regardless of what you choose, a window product with optimal energy efficiency installed with precision is critical to the performance of your windows over their lifetime. Read on to determine what is the best long-term solution when it comes to window replacements

Full Frame Window Replacements 

The Durability of Full Frame Replacement Windows

Full frame replacement is a more involved window replacement project. It includes the removal of all window components down to the studs in the wall. A new window and frame are installed into your window rough opening. The result of full frame window replacements is a long-lasting, high performing, energy saving window you can rely on. 

Pros: This is the top choice for homeowners who have damaged frames, interior trim casing, or exterior trim. When installed with modern spray foam insulation, the install can also help decrease noise infiltration, improve your home’s insulation and lower your energy and utility costs. If you have drafts in your home due to faulty windows, this is a great solution for you. 

One of the biggest benefits of full frame window replacement is the ability to inspect, repair, and mitigate any moisture intrusion that may have occurred over time from your previous windows. This will give you peace of mind that trouble isn’t brewing beneath the surface. Because full frame window replacement includes removing your interior and exterior trim, it may also require siding to be trimmed to fit your new windows into place. 

Cons: It’s a more significant initial investment to install full frame windows, but you will enjoy the benefits and optimal window performance for years to come. It may take two to three times longer to install full frames than inserts, but the extra time will give you peace of mind for many years as a result! 

Insert Window Replacement

The Simplicity of Inserts 

Also called “pocket window replacement” or “frame-in-frame” replacement, this involves the installation of a new window within the frame of your current window. What is replaced in this installation is the window sash (the parts that open and close) and hardware. When the new window is inserted into the existing, frame it is insulated, anchored, and sealed.   

Pros: If your current window frames are not damaged, and you want replacement windows that are the similar size and style, this may be a good option for you. Insert replacement limits disruption to your home exterior and interior window trim. It’s a quick and simple solution that offers a cost-effective means to replace your current windows with a much better efficient, aesthetically pleasing, and long lasting product when installed correctly.  

Cons: This is only an option if your current windows are structurally sound and made of wood or aluminum. Note: Pocket window replacement isn’t an option if you’re replacing vinyl windows because vinyl frames may not include the structure to support a window replacement. Realize that there may be a slight reduction of light when you choose window inserts vs. full frame window replacements, however many times the benefits outweigh the cons.
