3 Tips for Replacing a Large Picture Window

Picture windows are designed to let in lots of light and highlight a beautiful view. However, if your picture window breaks or needs reinstallation, its size can make it a little tricky. But that doesn’t mean you can’t get a great new picture window. The Window Source of the Rockies has picture windows to perfectly fit your home. In order to help you get started, this article will review the top three tips for replacing a large picture window.

Safely Remove the IG Unit

Even though it might seem scary, and many people try to avoid it, you’re going to need to remove the IG Unit. Don’t underestimate how sharp it can be. You’ll need to wear thick gloves, shoes, and safety eyewear, as well as a long sleeve shirt and pants.

Place a drop cloth below the window, put duct or masking tape over any cracks, and use a chisel to remove the glazing beads from the frame by twisting the chisel between the bead and the main frame. Only do this to the bottom and the side beads and keep the top bead in place to further secure the IG Unit. Next, use a utility knife and cut the sealant on the exterior of the window.

Because of the size, you’ll need lifting suction cups to help you remove the IG Unit. Once you’ve placed the suction cups (ideally in the middle), you can remove the last glazing bead. If you’ve fully removed the glazing beads and broken the seal, the IG Unit should lift up and out easily. The Window Source of the Rockies has the knowledge and tools to remove the broken IG unit safely.

Know Your Measurements

Before anything, you need to know the exact measurements of your window so that you can get the right replacement. First, measure the window’s top, bottom, and middle lengthwise and use the smaller of the three measurements as the width. You want to measure from one side of the frame to the other. If your window has a jamb surrounding it, you’ll also want to measure its width.

Although you’ll remove the jamb, it will help you see the opening’s overall size and the needed size of the replacement jamb lining. Lastly, you’ll want to measure the depth of the replacement window. Ideally, you’ll do this after removing the windowpane so that you can measure the shortest point of depth along the frame. Custom windows call for custom measurements. The Window Source of the Rockies will measure your window opening for a perfect fit.

Check Your Seal

After you’ve placed your window, you need to ensure the installation has a tight seal. You’ll see there’s a gap between the jambs and the framing. You’ll want to have backer rods on hand that are either three-quarters of an inch or one inch based on the size. The idea is to squeeze it into the gap until it’s completely full by pushing it in with a spatula tool. Once you’ve squeezed the backer rods in on all sides, use a high-quality caulk on top of the backer rods along all sides, smoothing out imperfections.
