To allow replacement handles for upvc windows seasonal expansion or contraction, subtract 1/8 inch each from the measurements of width and height. These measurements can be taken to a hardware or home center store to have a piece cut of glass that is in stock to the correct size. You can cut the glass yourself if you possess the right tools.

After installing the glass, apply some caulking on the edges. This will make the glass weatherproof. Install a glazier's point on both sides of the frame. This will secure the pane. The points shouldn't be too tight that they create friction between the sash and frame but they shouldn't be loose.

Before applying the putty to the surface, knead thoroughly until it is soft and free of lumps. Then, roll it into pencil-size strips. The first strip should be glued to the frame's corner. Work from one corner to the next and ensure that it is even and smooth.

Glazier's Points

The glazier's points are the small triangular pieces of metal which help to secure glass into a window frame without scratching or damaging the delicate surface. Learning how to use these little helpers is easy and can save you money on professional installation or the cost of new glass.

Note down the exact dimensions of the frame. These dimensions can be taken to the hardware or home center store and the new pane will be cut to a smaller size. This will ensure a snug fit, and allow for expansion and contraction.

Insert the new pane into the frame and push firmly with your hands. Utilize the chisel's point or the back of the putty blade to tap the glazier's points, as illustrated in Figure 11.

After the glazing compound dries, you're ready to install the new window sash. First, coat the wood with a thick coat of Linseed oil. This will prevent the newly-created putty from drying out and 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 tool or the back of the handle to gently smash the new sash or glazier's point into rabbet grooves. Repeat this process in intervals of 10 inches all around the frame.

Putty

A baseball thrown or a rock thrown in error, or a tree falling could result in a broken or cracked window pane. Fortunately, windows can be replaced by simply placing a new piece in the right place. The glass is held into place by a small metal clip, called a glazier’s point and putty. This compound is also referred to as glazing compound.

Remove the glazing points from the rabbets, or the grooves in the sash where the glass sits. If they are hard to chisel, hold the hand tool, Replace window Pane like a heat gun over them to soften first. When using a heating tool, make sure to not scratch the sash or its railings.

Create a bed for your new pane after removing the old putty and glazing points. Roll a rope of glazing compound between your fingers and make it around 1/2 inch thick. Then, push it into the rabbets where the glass will sit. The glass should rest against the putty on both sides. If you need to gently tap your glass into the rabbet using your thumb.

If the new pane has a crack you can fill it with a solvent-based glue or silicone caulk prior to pressing it into the sash. If not, you'll have to apply putty on the crack to form an airtight seal and keep water out. After the putty is dry and the film is oily, wipe it off the glass using an abrasive and allow it to dry completely prior to painting. Paint before the putty is completely dry.

These are small metal triangles that function as "nails" that hold the window in place. They are buried beneath a bead or glazing glue that hardens to solid wedge that holds the wood frame in place and hides the points.

After taking off the old pane clean the frame and wood. Scrape off any paint and sand down the rabbet grooves, where the glazing points used to be. Sand them 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.

Next, measure the dimensions of the window opening. You will need to measure 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 also allow for expansion and contraction of the glass during seasonal change. Take these dimensions to your local hardware or home improvement store and ask them to cut you cut the glass 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.
