Glass
If your single pane windows are old, deteriorating or broken, replacing them with newer glass that is tempered or insulated will increase energy efficiency and decrease noise while preserving the historical integrity of older homes. The replacement of a window pane is relatively easy and can be completed by most homeowners who possess basic hand tools. Alongside a
replacement double glazing windows pane, the following tools are needed: latex glazing putty; glazier's points; pliers; and a heat gun for warming the old putty, if needed. Wear safety glasses and gloves prior to starting. Working with broken glass could result in serious injuries.
Begin by removing any broken pieces of glass. This is best accomplished with the help of pliers however, a flathead screwdriver may be effective in a pinch. Use a wood chisel, or putty knives to remove any old putty that remains around the frame and the window sash. Be careful to not break the window sash. Take your time and work slowly. It is recommended to do this on a stable ladder rather than on the ground, and to place someone on the sash to help hold it steady.
Make sure the
window handle replacement frame is ready to receive the new pane when you have removed the old putty. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of the width and height. Take these measurements to the nearest hardware store or home center, and get a piece of stock glass cut to size. You can cut the glass yourself if you possess the right tools.
After putting in the new glass, apply caulking to the edge. This will make the glass weatherproof. Install a glazier's pointing on both sides of the frame. This will help secure the pane. The points should not be too tight that they cause friction between the frame and the sash however they should not be loose.
Before applying the putty make sure to knead it until it is smooth and free of lumps. Cut it into pencil-sized pieces. Apply the first strip in the corner of the frame, working from one corner to the other to ensure it is even and smooth.
Glazier's Points
The glazier’s points are small triangular metal pieces that help secure the glass to the frame without causing any damage to the fragile surface. Understanding how to use these hidden little helpers is easy and can save you money on a professional installation or
Replace Window Pane the cost of purchasing new glass.
After removing the old putty, glazier points and any leftovers, clean the frame thoroughly using a utility knife. If necessary, lightly sand the wood along rabbet grooves to smooth rough areas. If you do sand the wood, make sure to protect it by using painter's tape to prevent accidental damage.
Note down the exact dimensions of the frame. Bring these measurements to a hardware store or a home center and have the new pane cut slightly smaller than the frame's opening. This will ensure a secure fit, and allow for expansion and contraction.
Place the new pane into the frame and push it in with your hands. Use the point of the chisel, or the back of the putty knife to smudge the glazier's points, as shown in Figure 11. The glazier's points should be aligned with the top edge of your pane and the shoulders should be just beneath that lip.
Apply a thin layer of glazing compound to the rabbet grooves and edges of new glass. This will seal and protect the edges. Allow it to dry and cure fully.
Install the new window sash once the glazing compound has dried. The first step is to coat the wood with a thick coat of Linseed oil. This will stop the new putty from sucking up the moisture and drying out and cracking with time. Apply the coat using a brush or the tip of your knife, and then employ the chisel or back end from the putty knife to gently hammer the new sash and glazier's point into the rabbet grooves. Repeat this process at intervals of 10 inches all around the frame.
Putty
A baseball thrown at you or an unintentional rock, or a falling branch can cause a window pane to crack or break. Fortunately, the majority of windows can be easily replaced by simply putting a new piece in place. The glass is held into position by a small metal clip, called a glazier's point and putty. This compound is also known as glazing compound. Remove the old pane and clean the area with the rag, a pull-type scraper or wood chisel. Wear gloves and safety glasses when you work. If the window is attached to the frame, you'll need use a heat gun to soften the adhesive prior to prying it free.
If you're planning to install the original sash, gently remove any molding pieces that hold the old pane in place. Then, sand the sash to ensure it's smooth and ready for a new caulk. After the sash has been reinstalled, you can apply a silicone caulk on the glass. This will ensure that it doesn't be leaking or fade over time.
Remove the glazing points from the rabbets. These are the grooves in the sash, which is where the glass is located. If they're difficult to work out, you can try holding a hand tool like a heat gun over them to soften them up first. If you're using a heating gun, be careful not to cause damage to the railings of the sash or the sash itself by using the tool too closely.
Make the bed for your new pane after removing the old glaze points and putty. Roll a rope with glazing compound between your fingers, and make it around 1/2 inch thick. Then, push it into the rabbets where the glass will rest. It's important that the glass sits on the putty on each side If you have to do so, gently tap the glass into the rabbet using your thumb.
If the new pane has damaged, you can use a silicone caulk or glass glue based on solvents to fill in the crack before pressing it in the sash. If the crack is not sealed, you will need to use putty to keep water out. After the putty has dried remove the oily film off of the glass and let it dry completely before painting. If you paint before the putty is fully dry, it will not form a solid seal and could be leaking or discoloring in time.
Paint
You might be worried about replacing a broken pane of glass. But the truth is that replacing a single glass pane doesn't have to break the bank if you do it yourself. In fact, even a double-pane window can be replaced for a fraction of the cost of a professional.
If you're working with a large glass window, first make sure it is securely attached to the frame. Using the proper tools and techniques you can make this task relatively easy and quick.
When you are ready to start taking down the old window pane. Remove the metal glazing points attached to it. These are small metal triangles that function as "nails" to hold the window within the frame. They are submerged beneath a glaze putty or bead which hardens into an unbreakable wedge that holds the frame securely in place and hides the sharp edges.
Once you have the old pane removed clean the surrounding frame and wood. Scrape off any paint that has been used and sand down the rabbet grooves where the glazing points were. Sand them down to bare wooden surfaces, allowing you to paint the frames the same shade. After sanding the wood you can apply a layer flax oil. This will help to prolong the life of the frame.
Then, you need to measure the size of the window opening. It is necessary to take horizontal and vertical measurements of the entire opening, as well as the thickness of the old pane.
