Glazing can have a significant impact on the efficiency of your house. This is especially true in older double-glazed windows.
It is possible to replace the glazing points by putting the window in place however it is much simpler and quicker to remove the glass and frame. It is a good time to replace the seals made of rubber.
Broken Glass
Broken glass isn't just unattractive but can also let valuable heat and sunlight escape from your home. It's possible to fix damaged glass without replacing the entire window.
Start by putting on protective gloves and safety glasses. You can also apply duct tape or painter's taps to create an "X" on the glass you plan to remove. This will prevent any broken pieces from falling when you work, which could protect you from serious injury.
If you have a small crack in your window glass you can cover it with tape to keep out the elements like wind, water and insects. One strip of tape should be enough for superficial cracks but if you're worried about the weather becoming worse before you can replace your window, you should use an extra-strong plastic cover like a tarp or trash bag, to hold the glass in place until you obtain a permanent fix.
Make sure you use a strong adhesive designed for windows to fix cracks. Loctite Super Glue Glass is a good option. This high-tech glue was designed to bond to glass and dries transparent to give a perfect finish. Apply it to the cracks in the glass and let it dry completely before applying a new layer.
Stress cracks are another common issue that can affect your glass window. Stress cracks are usually caused by extreme temperature fluctuations and can spread rapidly across the entire window if they are not addressed. To stop stress cracks from occurring make an arc of a tiny size with glass cutters near the crack. This stops the crack from advancing, and may slow it down by a day or so.
Measure the frame of the broken window to determine the size of the new pane. It should be slightly smaller than the opening to allow for expansion and contraction and to compensate for any imperfections in the frame or glass. After cutting your new glass, apply glaziers compound around the edges of the frame and glass. After the compound has dried, paint over it to match the frame of the window.
Condensation on the inside of Double Glazed Windows
The appearance of condensation on the inside of double glazed windows usually indicates that the seal has failed at some point along the window unit. This is a serious issue because it could indicate that heat is being lost from your home through the window.
Double glazing has been designed to stop heat transfer between two glass panes by sandwiching a layer of air or a vacuum between them. This creates a seal that stops warm air from venting. If the glass is cooler than the frame, condensation could form on the glass and cause damage to the window. If you are unable remove condensation from a double-glazed window by opening windows or using extractors, dehumidifiers, or trickle venting, you may need an expert.
It's much rarer for condensation to appear on the outside of double glazed windows but it can occur in the event that the seal between the glass and window frame has begun to weaken. It is more common in winter, when the temperature is lower. This makes it easier for condensation. This is caused by an issue in the spacer that is used between the frame and the window. The spacer is made up of desiccant which is highly absorbent and will soak up any excess moisture.
This could result in moisture seeping through the gap when the desiccant is saturated. This can lead to condensation and water in the gap, and can be very difficult to eliminate.
Most reputable window companies offer a warranty and replace the unit and glass of the window if it's damaged by condensation. Report any problems as soon as possible to the window manufacturer so that the condensation can be repaired as quickly as possible to avoid further damage.
Shattering Window Glass
A damaged window could be more than an aesthetic issue. It could also pose the risk of injury, particularly when it's spreading. It is best to get it repaired as soon as possible. There are a variety of ways to do it, including using glass adhesives made for windows of vehicles and can be bought through the internet or at numerous auto maintenance stores. You can also use a glazing compound for home use, which is available at most hardware and home improvement stores.
Put on a thick pair of gloves and safety glasses before you begin any task. The area should be swept to remove any large shards. You should also vacuum any chips. This will prevent them from cutting you or a glass repair person later on.
It's better to stand on a ladder than on the ground. This will allow you to reach all parts of the frame more easily and also protect yourself from glass falling. Before you begin it's important to clean the rabbet. This is the area where glass will be placed. Clean it and then apply a coat of linseed oil to the rabbet, which will help the new putty stick to the frame securely.
After the frame is cleaned and the rabbet has been prepared It's time to prepare the replacement pane. Get a piece made of double strength glass that is 1/8 inch smaller in both directions. You'll need to purchase glass points which is a metallic triangle that holds the glass in place.
With the window sash removed from the way, carefully pry it away from the wood molding using a straight pry bar. You may have scrape off old glazing using a utility knife or chisel. Use the heat gun to warm any putty which isn't able to be removed easily. This will make it easier to peel it off.
After the frame has been removed from the mold then gently press the new glass into its place. Then, with a putty knife or glazier's point, fill the gaps around it and smooth them out. Once the putty is dry paint the frame to match. Paint the glass and the compound by overlapping the paint slightly.
Replacement Window Glass
If you're replacing a broken window pane, first wear gloves and eye protection to protect yourself from glass shatters. Tape off the area around the damaged window to stop it from breaking again in a different location when you take it off.
Make use of a utility knife to cut off the old glazing compound from the frame and glazing points (small triangles of metal). Clean the entire frame opening and then apply a coat of linseed to help the new putty adhere better.
Once the frame is ready, take measurements for a new window pane and purchase it from a local home improvement store or any other retailer. Be sure to purchase the pane 1/6th inch shorter in each direction than your measurement to allow for an ideal fit.
It's much easier than you think to put in the new window. However, it is crucial to follow the directions provided by the manufacturer to ensure a perfect fit and long-lasting replacement pane. Use a wirebrush for removing any old paint or wood gunk from the frame's opening. Then sand the wood down to the bare wood in order to improve the seal.
Use the point of the putty knife when installing the new window to bed it lightly against the wood frame. Put glazier's tips in the frame every six inches. This will keep the new pane securely in the frame.
After the frame has cured and the joint is painted, you can paint it several times to match the frame. Let the paint dry completely before you begin cleaning and maintaining your window.
