Glass

If your single pane windows are old broken, deteriorating or damaged, replacing them with newer glass that is tempered or insulated can increase energy efficiency and reduce noise while maintaining the historic integrity of older homes. A majority of homeowners with hand tools can repair the window pane. You will also need a replacement window seals upvc window handles [www.kmgosi.co.kr] window pane, glazier’s tips, pliers, and latex glaze putty. If needed you may make use of a heat gun to warm the old putty. Before beginning, wear gloves and safety goggles as working with broken glass could cause injuries.

Begin by removing any broken pieces of glass. It is recommended to use pliers for this however a flathead could be used equally. After that, use a wood chisel or putty knife remove the remaining old putty from around the frame and the sash. Be careful to not scratch the window sash. Be careful and slow. This should be done on an elevated ladder, not on the ground. Also, have someone on the ground to ensure it is held steady.

After you have removed all the old putty, it is time to prepare the window frame to fit the new pane. Take measurements of the width and height of the opening in the sash by subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be taken to a home center or hardware store to have cut a piece of stock glass to the right size. Alternatively, you can cut the glass yourself if you have the appropriate tools.

After installing the glass, apply some caulking on the edges. This will make the glass weatherproof. Install a glazier’s pointing on both sides of the frame. This will secure the pane. The points should not be too tight that they cause friction between the frame and sash however they should not be loose.

Before applying the putty work it in a gentle manner until it’s soft and free of lumps. Then make it into pencil-sized strips. The first strip should be glued to the corner of the frame. Work from one corner to another and ensure that 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 damaging the delicate surface. Learning how to use these tiny pieces of help is simple and can save you money on professional installation or the cost of purchasing new glass.

After taking off the old putty, glazier points as well as any remaining residue, clean the frame thoroughly using an utility knife. If necessary you can lightly sand the wood along the rabbet grooves to smooth out rough areas. If you decide to sand wood, cover it with painter’s tape to prevent accidental damage.

Take the dimensions of the frame and note down precise measurements. Take these measurements to an hardware store or home center, and have the new pane made slightly smaller than the frame’s opening. This will ensure a secure fit and will allow room for expansion and contraction.

Insert the new pane into the frame and push it in using your hands. Make use of the chisel’s point, or the edge of the putty blade to smudge the glazier’s points, as illustrated in Figure 11. When you’re done taping, they should be in line with the top edge of the pane and the shoulders that are raised of the points should be below the rabbet’s rim groove.

Apply a thin layer glazing compound to the rabbet grooves and edges of the new glass. This will protect and seal the edges. Let it dry completely and cure.

Install the new window sash once the glazing compound has dried. First, coat the wood with a heavy coat of linseed oil. This will prevent the new putty drying out or cracking due to the moisture it absorbs. Use a brush to apply this coat, or the point of the putty blade. Then use the chisel on the back of the putty tool or the back of the handle to gently hammer the new sash or glazier’s point into the grooves of the rabbet. Repeat this process every 10 inches around the frame’s perimeter.

Putty

A hurled baseball or a rock that is errant or a fallen branch can cause a window pane to break or crack. Fortunately, the majority of windows can be easily replaced by simply putting a new piece of glass in its the proper place. The glass is held in the position with a tiny metal clip, also known as the glazier’s point, and putty. This compound is also called glazing compound. Remove the old pane and clean the area with the rag, a scraper that is a pull type or a wood chisel. Wear protective glasses and gloves when working. You’ll require a heat gun in the event that the window is glued to the frame.

If you’re planning to install the original sash, remove the molding pieces that hold the old pane in place. Then sand the sash to ensure it’s smooth and ready for new caulk. After the sash has been reinstalled it is possible to apply a silicone caulk over the glass. This will ensure that it doesn’t get soiled or discolor over time.

Take the glazing points out of the rabbets, the grooves in the sash that the glass is. If they’re hard to cut, place the hand tool, like a heat gun over them for a few minutes to soften them. When using a heated tool, be careful to avoid damaging the sash or its railings.

Once the old glazing points and putty are removed, make a bed for the new pane. Roll a rope made of glazing compound between your fingers and make it about 1/2 inch thick. Then, you can press it into the rabbets where the glass will rest. It’s important that the glass is positioned against the putty on each side, so if you need to, lightly tap the glass into the rabbet using your thumb.

If the new pane has a crack, you can cover it with a solvent-based glass glue or Replacement upvc window handles silicone caulk before pressing it into the sash. If not, you’ll have to putty over the crack to form an impervious seal to keep water out. After the putty has dried remove the oily film off the glass and let it dry completely before painting. If you paint before the putty is completely dry, it won’t form a strong seal and may leak or discolor in time.

Paint

If you’ve had a broken window pane, then you may be worried about the expense of replacing it. It’s true that replacing a single piece of glass doesn’t need to be costly when you do it on your own. In fact windows with double panes can be replaced for a fraction of the cost of an expert.

First, if you are working on a large-sized window, ensure that it is securely fixed to the frame. This can be done relatively easy and fast using the right tools and techniques.

When you are ready to begin with the removal of the window pane. Pry out the metal glazing points that are attached to it. These are essentially small metal triangles that act as “nails” which hold the window in place in the wood frame. They are submerged beneath a bead or glazing glue that hardens to a solid wedge that holds the frame in place and conceals the edges.

After you have the old pane removed Clean up the frame and wood. Scrape off any paint and sand down the rabbet grooves, where the glazing points used to be. These should be sanded to bare wood, to allow you to paint them the same color as the rest of the frame. After sanding, apply a layer of flax oil to the wood that is not sanded down to extend the life of the frame.

The next step is to determine the size of the window opening. You’ll need to determine the vertical and horizontal dimensions of the entire opening, as well as the thickness. To get the exact size of the new pane, subtract 1/8 inch from both measurements. This will allow for seasonal changes in the glass. You can bring these measurements to a hardware or home improvement store and have the glass cut for you.

Now, it’s time to bed the new window pane. To do this, place the pane inside the frame and move it around until a 1/16 inch of putty remains between the edge of the glass and the sash on all four sides. Use a putty knife to smear the putty evenly, making sure that there isn’t an excessive amount of excess putty in the corners and along the edges. When the putty dries, it can be painted with the same color as the frame to prevent water and air from leaking into the frame and causing fogging.
