ull-Frame Installation:

• Definition: This type of installation involves removing the entire existing window, including the frame, trim, and sometimes even the surrounding wall. The new window is installed in a completely new frame.
• When It’s Needed: Full-frame installation is usually required when the window frame is damaged, rotting, or poorly insulated. It’s also necessary if you’re changing the size or style of the window (e.g., going from a smaller window to a larger one).
• Benefits: Offers better energy efficiency and seals because it allows for a fresh start with a new frame. It also provides the opportunity to replace or update any damaged or deteriorating wood or materials around the window.

Insert Window Installation (Retrofit Installation):

• Definition: In this case, a new window is installed directly into the existing frame, without removing the old frame or trim. The new window is designed to fit within the old frame, so it’s more of a “replacement” than a full installation.
• When It’s Needed: This is the preferred method when the existing window frame is still in good condition, and you simply want to replace the glass or improve the window’s energy efficiency.
• Benefits: It’s faster and more cost-effective than a full-frame installation, and it leaves the interior and exterior trim intact. It also minimizes the disruption to the surrounding area.
