Glazing can make a big difference to the energy efficiency of your home. This is particularly true for older double-glazed windows.
While it is possible to replace glazing points while the window is in position, it is simpler and quicker if the glass and frame are removed. It is a good time to replace the rubber seals.
Broken Glass
Cracked glass isn't just unsightly but it also allows valuable sunlight and heat escape your home. Fortunately, it's possible to fix a broken window pane without the need for a complete replacement.
Start by putting on protective gloves and safety goggles. You should also put a piece of tape with an "X" shape on the glass you intend to remove (duct or painter's tap works well). This will stop any broken pieces from falling while you work, which could save you from serious injury.
Cover a small scratch on your window glass using tape to keep insects, water and wind out. If the crack is only superficial and only a single strip tape will be enough. However, if the weather is likely to get worse before you can replace the window, you might want to use a heavy-duty plastic cover, such as the trash bag or tarp.
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 then dries crystal clear for an ideal finish. Apply it to the crack and let it completely dry before applying a new layer.
Glass windows may also develop stress cracks. Stress cracks are typically caused by large temperature changes and can rapidly spread across the entire window if they are not repaired. To stop stress cracks from occurring make a small arc with glass cutters near the crack. This will stop the crack from expanding and reducing the severity for several days.
Examine 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 your new glass, apply glaziers' compound around the edges of the frame and glass. Once the compound has dried, paint it to match the frame.
Double Glazed Windows Condensation Inside
Condensation inside double-glazed windows is typically an indication that the seal along the window unit has failed. This is an important issue since it means that the heat that is coming from your home is lost through the window and can be costly to both you and your energy bills.
Double glazing is designed to block heat transfer between two panes, by sandwiching an air or vacuum layer between them. This creates an airtight seal and stops warm air from escaping the house. If the glass is warmer than the frame, condensation can form on the glass and cause damage to the window. If you have condensation on your double-glazed window and you cannot resolve it by opening the windows, by using extractor fans, dehumidifiers or trickle venting then you may need to contact a professional.
Condensation of the outside of double-glazed windows is uncommon, but it can occur when the seal has begun to weaken between the glass and the window frame. This is more frequent in winter when the temperature is lower, making it easier for condensation to develop. This is caused by a defect in the spacer used between the frame and the window. The spacer usually contains desiccant which is highly absorbent and can absorb excess moisture.
This can lead to water leaking through the gap when the desiccant is saturated. This could lead to condensation and water leaking into the gap, and can be very difficult to eliminate.
Most reputable window companies offer a warranty and replace the glass and unit of a window if it's damaged by condensation. Make sure to report any issues as soon as possible to your window installer to ensure that the condensation is repaired as soon as possible to avoid further damage.
Shattering Window Glass
A damaged window is more than an aesthetic issue. It could also pose a safety risk, especially if it is spreading. It's best to get it repaired as soon as you can. There are a variety of ways to go about it by using glass adhesives made for windows of vehicles and can be bought through the internet or at numerous auto repair shops. Alternately, you can use a glazing compound intended for use at home, which can be found at a variety of hardware or home improvement stores.
Put on a thick pair of gloves and safety glasses before you start any work. Sweep the area to get rid of any large shards. Also, you should vacuum up any chips. This will prevent them from cutting you or a glazing repair person later on.
It is better to climb a ladder rather than on the ground. This will let you reach all parts of the frame with ease and will protect your glass from falling. It's also recommended to wash the rabbet prior to starting with the installation. This is the part of the frame around the window frame that is where glass will be. Apply a coat linseed to the rabbet and then wipe it clean. This will aid in helping the putty adhere.
Once the frame is cleaned and the rabbet prepared, it's the time to get ready for the replacement of the damaged pane. Find the height and width of the opening both ways Then, you can order an item of double-strength glass that's 1/8 inch shorter in both directions. You'll need to purchase glass points, which is a metal triangle that holds the glass in place.
After removing the window sash and the pry-bar flat, use it to carefully pry the sash free of the wood moulding. You may have to scrape old glazing putty off with a utility blade or chisel. Then make use of the heat gun to warm any putty that doesn't come off. This will make it easier to peel off.
After the frame is removed from the molding and the frame is pressed gently into the new glass in its place. Then, with a putty knife or glazier's point, fill in the gaps around it and smooth them out. Once the putty has dried paint it to match the frame. 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 shards. Tape off the area around the damaged window to prevent it from shattering again in a different location when you take it off.
Begin by removing the old glaze compound and glazing points (small metal triangles) from the frame using a knife. Clean the frame opening and apply a layer of linseed oil to make the new stick of putty to it better.
Once the frame has been prepared, measure it to determine the dimensions of a new windowpane. Then purchase it at an home improvement store or another retailer. Make sure you order the pane 1/6th inch shorter in every direction than the measurement to ensure an ideal fit.
Installing the new window is easier than you think, but ensure you follow the directions of the manufacturer to ensure the correct fit and a 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 to bare wood to improve the seal between the frame and the sash.
Use double glazing repair of the putty knife while inserting the new pane to lightly place it against the frame made of wood. Then, press glazier's points into the frame every six inches to hold the new window firmly in place.
After the frame has cured then paint the new joint multiple times to match the frame. Let the paint completely dry before cleaning and maintaining your windows. Maintaining your windows in good shape and ensuring that they function properly will increase their life expectancy and improve the energy efficiency of your home. If your windows are older or not in great shape it is possible that you would be better off having replacing your windows completely. If you opt for this option, we suggest choosing a high-quality, insulated window to reduce your utility costs. The type of window you choose will also influence the total cost of your project.
