Because of its rigidity, the frames of windows are often made of a hard, resistant type of plastic.Great insulation is provided by the uPVC windows and they require relatively little maintenance.Unless you are installing the windows in a new house or apartment, you will need to uninstall the existing window frames first.The new frame should be set into the hole that you removed the old window frame from.
Step 1: Take the space into which you will install the window.
To find the height and width of the rectangular hole in your wall, use a tape measure.To get an accurate reading, measure the height and width of the space in 2 or 3 places.It is a good idea to measure the new window to make sure it will fit into the window opening.
Step 2: The screws holding the window in place need to be removed.
To remove the screws that hold the old window panels in the frame, you need an electric screwdriver with a head bit.This will make it easier to remove the frame.The old window is most likely trash anyways, even if the glass gets broken.
Step 3: Remove the window frame from the wall.
To cut through the sealant on the window frame, run a utility knife around the outer edges.You need to remove the screws from the window frame and the walls of your home.Press on the other end of the pry bar to wedge the window away from the wall.Don't damage the wall while you remove the window.The wall is not disposable.
Step 4: Use a mallet to hammer the old frame out of the wall.
Start by hitting a soft-headed mallet against the corners of the window frame.The frame will be prepared for removal after this loosens it up.Hammer around the inside edges of the frame if it is still tight.Lift the frame from the wall on the outside of the home.You will need someone to help you with this step if the window is large.You can dispose of the old window in the trash once you have removed it.If the window shattered while you were removing it, you need to pick up all of the glass shards.
Step 5: Don't leave any sealant around the window opening.
After the old window is thrown away, you can use a putty knife and utility knife to cut off the debris around the opening of the window.As you install the new frame, the material will get in the way.It is possible to put all of this material into the trash.
Step 6: Purchase a slightly larger frame than the wall opening.
You can find high-quality windows at any window and door supply shop.Make sure the window you buy is 10 millimetres narrower than the space where you will install it.There is a gap between the end of the frame and the wall on either side.The gap in the wall should be the same height as the frame.The wall gap is 1,220 millimetres in width.The window frame should be 1,210 millimetres in width.The window can expand and contract as it warms up and cools down during the day if there is extra space on the sides of the window frame.
Step 7: Super glue was used to fit the endcaps.
The lower edges of the uPVC sills are separated from the frame by the small pieces of plastic that cap them off.Wrap the outer edges of the end caps with superglue.They should be put into the openings at the lower left and right corners.The window frame should have an installation guide that will show you where they go.Water can get into the corners of the windows.The entire frame could be broken if water got in.
Step 8: The bottom of the frame has a sill.
The window frame has screws that are designed to hold pieces of the plastic together.The screws should be inserted into the holes in the sill.Line the sill up with the window frame by putting the screws in the holes.Attach the frame with the help of your electric screwdriver and tighten the screws in place.The frame and sill are plastic, so you could over tighten the screws to crack them.Continue to tighten them until they don't turn anymore.
Step 9: Silicone caulk can be used to seal the window sill.
To prevent water from getting into the window frame, run a line of caulk around the open areas.Silicone caulk can be used on the small openings around where the endcaps meet the sill.It is a good idea to run a line of silicone over the other parts of the frame if you think water could enter it.
Step 10: Check the level of the new frame by lifting it into the wall opening.
Lift the window frame from the wall with another person's help.While one person holds it in place, the other should set a level on the sides, bottom, and top of the frame to make sure it is sitting evenly.Put plastic packers between the frame and the wall until it is level.It is common to install 2 packers on both sides of the frame to level it out.The pry bar needs to be inserted between the wall opening and the base of the uPVC frame.Break the packers off with a chisel if they stick out past the frame.
Step 11: Attach holes to the sides of the frame.
On the left and right sides of the frame, use your tape measure to measure from the top to the bottom.Use a pencil to mark the spots.To mark the spots on the top and bottom of the window frame, measure from the right and left sides.You can use your electric drill to make pilot holes.You should drill 2 pilot holes in the top, bottom, left, and right sides of the frame.
Step 12: The frame has 2 holes on the bottom.
There are two holes on the lower side of the frame that need to be covered with a pea-sized bead of silicone.It will seal them against water and prevent condensation from entering the bottom of the frame.It could freeze and crack the entire frame if it were to get into it.
Step 13: The fixing screws need to be drilled into the wall.
The screws are used to anchor the window into the wall.You can use a drill and a head bit to drive the screws through the frame.Make sure not to overtighten the screws in the wall by driving them in until they are tight.There is no metal in the window frames.They are relatively delicate because of this.It is important that you do not overtighten the screws in the frame.
Step 14: There are platforms in the inside of the sashes.
The platforms go into the glass panels.There are long pieces of rigid plastic on the Glazing platforms.At the top and bottom of the glass panels is where the insert 1 should be.The glass panels need to fit into the panels correctly.You won't need to install the platforms separately when you purchase the window.The sashes of a window frame hold individual panes of glass.The window frames usually contain at least 2 sashes.
Step 15: The glass panels need to be inserted into the window frame.
Since there will be multiple panes of glass on your windows, it's a good idea to match each one with the opening in the frame that fits it.First, put the bottom of the glass in the frame.Press the top edge of the glass pane into the sash when it is seated.The glass frames need to be pushed back so that they fit in place.Gloves are a good idea to keep the sharp edges of the glass from cutting your hand.The window kit should include the glazing tool.You can buy one at a hardware store.
Step 16: The beads should be put into the top, bottom, and sides of the sash.
At the outer edges of each glass frame, there are vinyl strips called Glazing beads that fit at the base of the sash.Match each bead to the edge of the glass.Place each bead at the point where the glass frame and the edge of the sash intersect, and gently hammer them into place with the soft-headed mallet.You don't need to pound on the beads with a hammer if they snap into place easily.
Step 17: There is a bead of caulk between the frame and the wall.
There is a small gap between the frame and the wall.Silicone caulk can be used to fill this.The window frame has an interior edge.When squeezing the caulk out of the tube, use a steady and consistent pressure to avoid breaks in the line of silicone.If the glass is dirty or covered in dust, use a chemical cleaner and a rag to clean it.
Step 18: The frame has an external surface.
Run a line of silicone sealant in the gap between your frame and wall, like you did on the internal surfaces.It is important that the line of sealant is intact.Water could enter between the frame and the wall if there are gaps.There is a seal below the window.To see below the windowsill, you will need to crouch down.Silicone sealant can be used to match the brick, wood, or vinyl on the outside of your home.This will not be as disruptive as white sealant.
