Glazing Repair - How to Repair a Cracked Window
Glazing can have a significant impact on the energy efficiency of your house. This is particularly true for older double-glazed Windows.
While it is possible to replace the glazing points when the window is still in position, it is simpler and quicker to do so if the frame and glass are removed. This is also a good opportunity to change the gaskets made of rubber.
Broken Glass
Cracked glass isn't just unsightly but can also let valuable heat and sunlight escape from your home. It's possible to fix a broken pane of glass without replacing the entire window.
Put on safety goggles and gloves. You can also employ duct tape or a painter's taps to create an "X" on the glass that you intend to remove. This will stop any broken pieces from falling as you work, which could protect you from serious injury.
If you've got a tiny scratch in your window glass, 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 such as a tarp or a trash bag, to hold the glass in place until you find a permanent solution.
For cracks that aren't as deep try using a tough adhesive designed specifically for windows, such as Loctite Super Glue Glass. This high-tech glue is made to adhere to glass and dries crystal clear for an ideal finish. Apply it to the cracks in the glass and let it dry completely before applying a second layer.
Stress cracks are another frequent issue that can affect your glass window. They're usually caused by significant temperature fluctuations, and can spread quickly across the entire glass window if it's not fixed. To prevent stress cracks make a small arc with a glass cutter near the crack. This will stop the crack from expanding and reducing the severity for several days.
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 cover any imperfections in the frame or glass. After cutting the glass, apply glaziers' compound around the edges of the frame and glass. Once the compound is dry, paint it to match the frame.
Double Glazed Windows Condensation Inside
Condensation on the inside of double-glazed windows is typically an indication that a seal along the window unit has failed. This is a major issue because it could indicate that heat is being lost from your home through the window.
Double glazing is designed to block heat transfer between two panes, by sandwiching an air or vacuum layer between them. This creates a secure seal that blocks warm air from escaping. If the glass is cooler than the frame, condensation can form on the glass and cause damage to the window. If you have condensation on your double glazed window that you are unable to eliminate it by opening the windows using extractor fans, using dehumidifiers or by trickle venting, then you may need to contact an expert.
Condensation of the outside of double-glazed windows is rare However, it could happen if the seal has begun to weaken between the glass and the window frame. This is more common in winter, when the temperature is lower and it's more easy for condensation to develop. The most likely cause is a fault in the spacer placed between the frame and the window. The spacer is made up of desiccant which is very absorbent and absorbs any excess moisture.
This could lead to moisture leaking into the gap when the desiccant is saturated. This could cause condensation and water to build in the gap which is difficult to clean out.
The positive side is that many trustworthy window manufacturers will provide warranties on their products. They will replace the glass and window unit in the event of damage caused by condensation. Inform any issues as quickly as possible to the window manufacturer so that the condensation is repaired as quickly as it can to avoid further damage.
Shattering Window Glass
A damaged or cracked window could be more than an aesthetic problem. It can also pose an injury risk, particularly when it's spreading. It is best to have it repaired as quickly as possible. Glass adhesives can be used for windows in vehicles which you can purchase on the internet or in many auto repair shops. You can also make use of a glazing compound formulated for home use, which can be found at a variety of hardware or home improvement stores.
Put on a thick pair of gloves and safety goggles before you start any work. The area should be swept to remove any large pieces of shards. You should also vacuum any chips. This will stop them from cutting you or a glass repair person in the future.
It's a good idea work on a ladder instead of laying on the floor. This will allow you to access all parts of the frame more easily and protect your glass from falling. Before you begin it's important to clean the rabbet. This is the area where the glass will be placed. Clean it and then apply a coat of linseed oil to the rabbet, which will allow the new putty to stick securely.
After the frame is cleaned and the rabbet is prepared It's now time to put together the replacement pane. Order a piece of double strength glass that is 1/8 inch smaller in both directions. You'll need to purchase glass points, which is a metal triangle that holds the glass in the right place.
With the window sash out of the way, gently pry it off of the wood molding with a straight pry bar. It is possible to scrape old glazing putty off using a utility knife or chisel. Make use of the heat gun to warm any putty which isn't able to be removed easily. This will make it much easier to peel it off.
Once the frame has been removed from the moulding and the frame is pressed gently into the new glass in its place. Fill in the gaps with the glazier's tip or a putty knife. Once the putty has dried paint it to match the rest of the frame. Paint a little bit over the edge of the compound, then onto the glass to seal it completely.
Replacement Window Glass
Wear protective eyewear and gloves when replacing a damaged pane of glass. Tape off the area around the broken window to prevent it from breaking again in a different location when you take it off.
Utilize a utility blade to cut off the old glazing compound from the frame and glazing points (small triangles of metal). Clean the frame opening and apply a layer of linseed oil to help the new putty stick to it better.
After the frame is prepared, measure it to determine the dimensions of the new windowpane. Then purchase it at an home improvement store or other retailer. The panes should be 1/6th inch smaller in each direction than you measurement. This will ensure a perfect fit.
Installing double glazing window repairs is much easier than you think, however make sure you follow the instructions of the manufacturer to ensure the proper fit and a long life span for your new pane. Use a wirebrush to remove any old paint or wood gunk from the frame opening. Then sand the wood until it is the wood's surface to strengthen the seal.
Use the edge of the putty blade when inserting the new pane to lay it gently against the frame of wood. Press glazier's tips into the frame every six inches. This will help hold the new pane securely in the frame.
After the frame has cured then paint the new joint several times to match the frame. Let the paint completely dry before you begin cleaning and maintaining your window. Maintaining windows in good condition and ensuring that they function properly will increase their life expectancy and improve the energy efficiency of your home.
