Many people do not realize that regardless of which replacement window you choose, there are two different ways to install the window. It is essential for you to know the difference between full frame window installation and retrofit window installation to get the right install for your home.

Full Frame Window Installation

Full frame window installations require that the existing window and all of its supports are removed, including the trim and sill. The new window is then installed right into the framing of the home. The trim and sill are then replaced, and sometimes the internal trim.

Full frame replacement may be preferred if there are issues with the exterior or interior wall near the window. Occasionally, the interior or exterior trim (or even the windowsill) can been damaged or infested with bugs or mould. This is one reason to go with vinyl in the future– vinyl can’t rot and is more durable than traditional wooden window elements.

The Pros and Cons of Full Frame Window Installation

If your window is damaged, it’s much better to start with a blank slate and correct the underlying issue. Remember, professional window installers will always inspect and look out for structural or cosmetic issues in your home that might impact the performance of your new windows.

New homes are less likely to need full frame replacements. But, even if it’s not required, you may want a full frame install because it gives you more choice in window materials and style.

Full frame window installation is more expensive than a retrofit window installation. It takes more time and extra materials. You also need to be careful to match the trim and sill to the style and colour of the rest of your home.

Retrofit Windows

The alternative is retrofit window installation. Also called an insert or replacement window. This window installation method essentially means placing a slightly smaller window into your old window’s spot. The trim and sill remain unchanged.

The Pros and Cons of Retrofit Window Installation

If there are no problems with the existing window elements you can have a retrofit window installed. It takes less time and uses the same trim and sill. This can reduce your costs significantly.

However, this installation method requires more glass area. This might reduce your view and limit how much light comes through the window.

If installed poorly a retrofit window may not be level, may not be sealed correctly, or may be difficult to open. That’s why you should choose the professionals and expert team at Thermo-Bilt Windows and Doors. You can rest assured your windows are perfectly installed every time.
