Can Broken Glass in a Double-Pane Window be Repaired?

Introduction to Double-Pane Windows

It may have been storm damage or it may have been the ball thrown by your kids, but your double-pane window is now broken. Your first question: can this be fixed or do we have to replace the entire window? The answer: yes, it can be fixed, but the fix may not be as simple as the answer.

Can Broken Glass in a Double-Pane Window be Repaired

The Structure

Double-pane windows are two panes of glass that can either be tempered or laminated, held in a single frame, but not touching. The space between the two panes of glass is created by spacers and is a sealed vacuum or is filled with a non-toxic gas. The size of the space between the two panes typically ranges from ¼ to ¾ of an inch thick. You may also hear double-pane windows called: dual pane, double glazing, and insulating glass.

The Benefits

The first thing you will notice when you install double-pane windows after having single-pane windows is the regulation of temperature. The space between the two panes of glass slows the transfer of heat out so in the summer the heat is kept outside while in the winter it is kept inside. Double-pane windows also keep your home healthier than single-pane windows by providing an extra barrier against airborne particles and harmful ultraviolet rays. Finally, outside noise can be reduced by 43% making the inside of your home quieter for you to enjoy.

Types of Repairs to Broken Double-Paned Windows

There are three ways to repair a double-paned window: 1. The entire window, from the frame to the sashes inside, are replaced., 2. Replace the sash alone., and 3. Enlist a window contractor to have a custom glass assembly specifically built for the window.

Repairing the Window vs. Replacing the Window

When glass in a double-paned window is broken, both panes of glass need to be replaced because the vacuum between the two panes of glass has been undone or the non-toxic gas inserted between the two panes has escaped depending on how the double-pane window was constructed. You may repair glass if it is not shattered with an adhesive that is placed within the cracks as a putty or a special tape that will help prevent the glass from cracking further. This is only a short-term solution because the gas between the panels is no longer there. If the glass, on one or both panels, is shattered a replacement is needed. If the frame is not damaged, the frame will not have to be replaced.

Installing the New Double-Pane Window

If you consider yourself a DIYer you may be able to replace the new window assembly by yourself. Here are the steps you will need to take to install your new double-pane window.

  1. Start by removing the sash from the window and placing it broken side down on a cloth.
  2. Use a pry bar and rubber mallet to remove the window stops holding the window into the frame.
  3. Use a utility knife to cut the sealant holding the glass into the frame (the opposite side from the removable window stops. Be careful of the broken glass and be sure to cut all the way through the sealant on all four sides.
  4. Carefully turn the window sash over so the broken side is down. Carefully press the broken window assembly out of the frame. Clean up the edges around the sash to allow for a good seal.
  5. Squeeze caulk around the inner perimeter of the sash, where it comes in contact with the glass assembly. Apply a thick bead, but don’t apply so much that it will squeeze out and dry on the glass.
  6. Lift the new glass assembly up and carefully place it into the bead of caulk around the interior edge of the window. Press down firmly and then reinstall the window stops with a rubber mallet.
  7. Replace the window in the opening and reconnect any of the hardware that typically holds it in place. Secure the window and allow the sealant to cure for 48 hours before cranking the window open or closed.
