Insert vs. Full Frame Replacement: Which Is Right for My Home?

November 04, 2021

Renewal by Andersen® windows aren’t “one size fits all.” That’s why we offer two different methods of installing our replacement windows. Read on to learn which replacement method could be the right fit for your home.

The Insert Window Installation Method

An insert window is a new window that is inserted into an existing frame. This method is a good option if the old frame and sill are still in good condition, or if you don’t want the casing and trim around the window to be removed during the installation.

Here’s How It Works: During an insert window installation, one of our professionals will take out the sash, interior and exterior stops and any interfering trim or hardware. Next, they’ll remove any weights and pulleys and insulate gaps and weight pockets left behind. The frame surface is then readied, and the insert is placed in the prepared opening, leaving the casing and frame intact throughout the entire process.

The Result: An energy-efficient window with High-Performance Low-E4® SmartSun™ glass and strong, sleek Fibrex® material that gives you a thinner frame and more visible glass area than other replacement window options.

The Full Frame Window Installation Method

If your old window frame leaks or is warped or rotted, you’ll want to go with a full frame window replacement. This is also the preferred method if you’re opting for a larger window style or your home requires large window openings due to fire egress codes.

With a full frame replacement, the entire window – sash, frame and trim – is removed, leaving a rough opening. The installer then inspects the structural framing, repairing or replacing materials as needed. The drip cap and flashing are both thoroughly checked to ensure that no moisture can make its way into the walls surrounding the new window. Then any gaps are filled with insulation and the opening is prepped for the new window.
Next, the is placed in the prepared opening and brought to square, insulated and cased with trim.

The Result: An extremely strong window made of Fibrex material with highly energy-efficient High-Performance Low-E4® SmartSun™ glass of new construction quality.
