Glazing can have a significant effect on the energy efficiency of your home. This is particularly important for older double-glazed Windows.
It is possible to replace glazing points by putting the window still in place, however it is much simpler and quicker if you remove the frame and glass. This is also a great occasion to replace the rubber gaskets.
Broken Glass
Windows that are cracked aren't just unattractive, but also let valuable heat and sunshine to escape your home. Fortunately, it's possible to fix a broken window without the need for a complete replacement.
Wear safety glasses and gloves. Also, you should put an X-shaped piece of tape an "X" shape on the glass you intend to remove (duct or painter's tap works well). This will prevent any broken pieces from falling as you work, which could protect you from serious injury.
Cover a small scratch on your window glass using tape to keep water, insects, and wind out. One strip of tape should be sufficient for cracks with a superficial appearance but if you're worried about the weather getting worse before you can replace your window, you should use a heavier-duty plastic cover, like a tarp or trash bag, to hold the glass in place until you can find a permanent solution.
For cracks that aren't quite as shallow Try using a strong adhesive that is specifically designed for windows, like Loctite Super Glue Glass. This high-tech adhesive is designed to adhere to glass and dries crystal clear for the perfect finish. Apply it to the cracks in the glass and allow it to dry completely before applying a new layer.
Glass windows may also develop stress cracks. Stress cracks are typically caused by extreme temperature fluctuations and can spread rapidly across the entire window if not fixed. To prevent stress cracks create a small arc with glass cutters close to the crack. This will prevent the crack from expanding and reducing the severity for a few days.
Examine the frame of the broken window to determine the size of the new pane. It should be slightly larger than the opening in order to allow for expansion and contracting, as well as to account for any imperfections in the frame or on the glass. After cutting the glass, apply glaziers' compound around the edges of the frame and glass. After the compound has dried paint it to match the frame.
Condensation inside of Double Glazed Windows
Condensation inside double-glazed windows is typically an indication that a seal along the window unit has failed. This is a serious problem, as it can indicate that heat is being lost from your home through the window.
Double glazing has been designed to block heat transfer between two panes of glass by sandwiching a layer air or a vacuum between them. This creates an airtight seal and keeps warm air from exiting the home. However, if the glass is cold or colder than the surrounding frame, then condensation can build up on it, which can damage the window. If you notice condensation on your double glazed window and you are unable to resolve it by opening the windows by using extractor fans, dehumidifiers, or by trickle venting, then you may require the help of a professional.
Condensation of the outside of double-glazed windows is uncommon, but it can occur if the seal has begun to break down between the glass and the window frame. This is more frequent in winter as the temperatures are lower and it's more easy for condensation to form. The most likely cause is a defect in the spacer that is used between the frame and the window. The spacer is made up of desiccant which is very absorbent and will absorb any excess moisture.
This can lead to moisture leaking into the gap once the desiccant is saturated. This could cause condensation and water to build within the gap, which is difficult to get rid of.
Most reputable window companies offer a warranty and replace the glass and unit of a window if it's damaged due to condensation. It's essential to report any issues to your window installer as soon as you spot them so that condensation can be addressed as soon as possible to prevent further damage to the window unit and the surrounding frame.
Shattering Window Glass
A cracked window pane isn't just an aesthetic issue, it can also pose a security risk, especially if the crack has been spreading. It is best to get it repaired as quickly as you can. Glass adhesives can be used for window glass in your vehicle that can be purchased online or in many auto repair shops. You can also make use of a glazing compound for use at home that is readily available at many hardware and home improvement stores.
Put on a thick pair of gloves and safety goggles prior to start any task. The area should be swept to get rid of any large shards. Also, you should vacuum up any chips. This will stop them from cutting you or a glass repair technician in the future.
It's a good idea to work from a ladder, instead of standing on the ground. This will make it easier to reach all the areas of the frame and will ensure that you are safe from falling glass. Before double glazing window repairs begin it's best to clean the rabbet. This is the area that glass is placed. Clean it off and then apply an oil coat of linseed to the rabbet. This will help the new putty stick to the frame securely.
After the frame has been cleaned and the rabbet prepared It's now time to make the replacement pane. Measure the height and width of the opening both ways, then order an item of double-strength glass that is 1/8 inch smaller in both directions. You'll also need glass points, which are steel triangles which keep the glass in place.
With the window sash removed using a flat pry-bar to gently pull the sash away from the wood moulding. You may have to scrape off old glazing putty using a utility knife or chisel. Use the heat gun to warm any putty that won't come off easily. This will make it easier to remove it.
When the frame is out of the molding and the frame is firmly pressed, gently press the glass in the frame. Then, with a glazier's or putty knife's point, fill in the gaps around it and smooth the edges. Once the putty is dry, paint the frame to match. Paint a little bit over the edge of the compound, then onto the glass to completely seal it.
Replacement Window Glass
Wear a pair of gloves and eye protection when replacing a damaged pane of glass. Tape off the area around the damaged window to stop it from breaking again in a different area when you remove it.
Begin by removing the old glazing compound and glazing points (small metal triangles) from the wood frame using a knife. Then, clean the entire frame opening and apply a layer of linseed oil in order to help the new stick of putty to it better.
Once the frame is in place to be measured, you can take measurements for a new window pane and purchase it from a home improvement store or any other retailer. Be sure to purchase the pane 1/6th inch shorter in each direction than your measurement to ensure an ideal fit.
Installing the new window is easier than you think, but ensure you follow the manufacturer's directions to ensure a right fit and long-lasting life for your replacement pane. Use a wire brush to clear the frame opening of any old paint or wood gunk, and then sand it down to bare wood in order to increase the seal between the frame and the sash.
Use the edge of the putty knife while installing the new window to bed it lightly against the wood frame. Put glazier's tips in the frame every six inches. This will help hold the new pane securely in the frame.
Once the frame is cured, paint the new joint multiple times to match the frame. Allow the paint to dry completely before cleaning and maintaining your windows. Making sure your windows are clean and working properly will extend their useful lives and boost the efficiency of your home's energy usage. You may want to replace your windows if they are old or in poor condition. If you choose to go this option, we suggest you choose an energy-efficient, high-quality window that can reduce your energy costs. The type of window you choose will also impact the overall cost of your project.
