Repair of double glazed windows


In recent weeks, I've explained how to repair broken windows in your home. But what if you have double glazed windows? Is the process the same? Well, pretty much, except for a few variations. We invite you to review the one-part repair process and highlight the differences between double-pane windows.

When we start talking about double glazed windows, one of the first things that comes to mind is that of vinyl window frames instead of aluminum. When working with double glazed windows, you can have aluminum or vinyl frames, depending on the year of construction of the house. Double glazed glass became popular in the 1980s, but vinyl frames did not really become popular until the 1990s. So, if your home is less than 10 years old, chances are you'll have vinyl windows. In both cases, I will discuss the differences. Suppose you have an aluminum sliding window with two windows. The procedure for removing the opening frame and the opening glass is the same as for single glazed windows.

The differences are that the glass enters the frame about twice as far as the single-pane window. The single-pane glass has sunk 1/4 "into the surrounding rubber, so if both pieces of glass have been broken, you will need to order a new IGU unit at the local glass factory. knowledge of the width, height, total thickness and possibly the thickness of the glass The best way to obtain the dimensions is to measure the width and height of the rubber to the rubber, to note these figures, open it and place it -the on a table as we did with the single-pane window.Remove the screws from the opposite corners and pull the frame.You will see how far the glass enters the surrounding eraser. , then you want to add 1 "to the width and height you measured previously (1/2" times both sides = 1 ") .Then, measure the total thickness of the unit by removing the rubber glass edge

Generally, this dimension is 1/2 ", but not always. There is a metal spacer that divides the two panes. silver or bronze. If you want to get the same size spacer, you have to give the glassware the thickness of each piece of glass in the IGU. the unit is 1/2 ", so they will use a 1/4" spacer. If the glass is 3/32 "on both sides, they will use a 5/16" spacer. If you are not paying attention to the thickness of the spacer, you can request the 1/8 "thicker glass and they will automatically use a 1/4" spacer.

When you get the new IGU home, the installation is identical to the single-pane window. Now, what happens if only one side of the IGU has been broken? Many times, the outer flap breaks, but the inner flap is ok. You can order a brand new IGU As we just did or, if you are adventurous, you can order only the broken glass and replace it. I'll explain how to do it, then I'll tell you things that can go wrong. After placing the window shutter on the table with the surrounding frame removed, you will see a black rubber-like substance around the edge where the spacer is applied. This is a butyl sealant, and you must separate the broken glass from this butyl. The best way to do this is to take a knife with a new blade and pierce the butyl where it meets the broken glass. Then take a new hacksaw blade and push it into the area where you have spared the butyl from the glass. You do not want the hacksaw blade attached to a hacksaw. With the help of your hand, go back and forth while you go around the glass. This should allow you to remove the glass.

Once done, place rags on the right piece of glass to catch the debris and scrape the surface of the spacer that will be in contact with the new glass. Use a putty knife. Then remove the rags and debris. When you are ready to put on the new glass, clean the inside of the right piece of glass that you have not removed. Remember that once the new glass is installed, debris or fingerprints inside will be permanently sealed. So, clean it well and check it from all angles. Do the same on the side of the new glass that will go inside the UGI. Next, pass a thin bead of clear silicone over the entire perimeter of the spacer. Set your new window on the spacer and use finger pressure to glue the silicone glass all around. Then, enter by the side and run some silicone on the side where the glass and the spacer meet. Cover the window with something for 24 hours. You do not want to touch the IGU for 24 hours. The silicone must heal. After 24 hours, you can assemble the device and install it in the opening.

Some things can go wrong. The first leaves marks on the inner part of the glass. Once you seal the glass, you can not clean what's between the windows. The other thing involves condensation between the panes. If the slightest trace of silicone is present around the glass, there is a good chance that you will see as soon as the nights are cold and the days are warming up. You will have to decide if you are confident enough in your ability to do the job properly or if you prefer to pay more for it to be done for you. It's not because you pay someone to do it that you still will not experience the same problems. The difference is that they have to guarantee their IGU for at least a year. Over the years, I have received many units that had marks between windows. The beauty of this product is that the manufacturer can not dispute it because no one could do it except them.

OK, and if the window frames are vinyl rather than aluminum? Well, the main difference is that the glass in a vinyl window no longer has the rubber seal around the edge. You do not remove the screws from the opposite corners and separate the frame from the glass. What they do is put either silicone or double-sided tape on the lip of the frame where the glass rests. This is what keeps the glass in the frame, then they apply a stop on all four sides of the glass. You must first remove the stops, then flip the panel and break the seal that holds the glass on the frame with the help of a knife. Wear gloves during this procedure. If only one side of the UGI is broken, do not even think about repairing one side. You'll never get this IGU out of the frame without breaking the other piece of glass in the process. But, on the plus side, you can remove the stops without removing the panel if it's a slider. You can then measure the dimensions of the glass and control the new IGU. In this way, you eliminate the need to temporarily cover your window. The same is true for the stationary part of a slider or an image window. Before installing the new IGU, be sure to clean the lip that contains the tape or silicone and apply silicone or tape. One or the other will work.

You will discover that replacing an IGU in an aluminum window is much easier than a vinyl window. But in either case, you can do it yourself and save a few dollars.
