How to put new window frames in place In The Netherlands
1. Window Replacement Parts
Types Of Replacement Windows and styles
Instead of full-frame windows that are built for new construction, replacement windows can fit into existing window openings. They are available in many sizes from 11 1/2 inches up to 68 inches wide.There are three main types of replacement windows available: insert replacements, sash kits and full-frame units. We found a sash-replacement kit on the Newton house. It gives an old window frame new movable components, including jambliners and sash. The liners attach to the side jambs at the window opening. After that, the sash is slipped between them.
To make these work, your existing window frame must be square and level. A replacement insert window is a fully-assembled window that comes in a ready to install secondary frame. Insert replacements are sometimes called pocket windows. They fit into the existing opening, and then attach to the old side jambs. Because you're adding new jambs and liners, the glass area will be slightly smaller than it was before.
These windows can be used as replacements for inserts. However, they come with a complete frame which includes sill, side jambs and head jambs. These windows are your only choice if your old window frame, sill, and jambs is rotten. You will need to strip the window opening from its rough framing.
2. Measuring Replacements
The most important step in the window-replacement process happens long before installation day. This is when you measure the existing window frame in order to choose the right replacement unit. Here are some steps.- Measure the inside width from the old window frame jamb by jamb. Do this in three places: across its top, middle, or botWe. Write down the smallest of the three measurements.
- Next, measure the frame's height from the top of the sill to the underside of the head jamb in three places: at the left jamb, in the middle, and at the right. Keep the smallest measurement.
- Take the diagonals measuring from corner, corner, and back to check the frame's squareness. The dimensions should be equal. You can shim the replacement to fit if the frame is less than 1/4 inch square. Additional adjustments to the frame may be necessary. You may need to replace the entire frame if the frame is out of alignment.
- Finally, use an angle-measuring tool to determine the slope of the sill; some replacements come with a choice of sill angles.
3. The Sash is yours
- The first step is to remove the old sash from the window frame. To remove the lower sash, in most cases you will need to take off the wooden interior stops. If you plan to reinstall the stops (or if they are already removed), be careful. They can easily break.
- Next, take out the parting beads to free the upper sash. If the windows are like this, you won't see any beads if they were previously fitted to sash repair kits. Just press down on the jamb liner and pull the top of your sash forward.
- Then pivot one side of the sash upward to free it from the jamb liners.
4. Jamb Liners: Get Off!
- Use a flat bar to remove vinyl jamb liners or aluminum jamb liner from the window frame. If the original window is still in use, take out any wooden stops.
- The exterior and interior casings should be left intact.
5. Prep the Frame
- Take off any paint that has become brittle and scraped. Then, use exterior-grade wood putty such as Minwax to fill in any cracks.
- Next, sand the jambs and prime the surfaces.
6. Remove the Old Sash Weights
- If you have the original sashweights, remove them from the pockets and wrap the window frame in insulation.
- Pull out the weights by unscrewing each side jamb's access panel.
7. Prep for Insulation
We prefers polyurethane to fiberglass insulation.- Make sure to use only low-pressure, minimally expanding foam intended for windows and doors; anything else will bow the frames and keep the sash from working.
- First, pull out any existing fiberglass in the weight pockets.
- Then bore 3/8-inch-diameter holes, one near each end and one in the center, down through the sill and up through the head jamb.
8. Spray in the Foam
- You can push the expanding foam into holes until it starts to ooze. (We are using the commercial system. However, you can use foam from cans like Dow’s Great Stuff to accomplish the same task.
- Also spray foam into the sash-weight pockets in the side jambs. Allow the foam to set for at minimum 6 hours. After that, you can break it off or cut it flush to replace the sash-weight pockets panels.
9. Caulk the Open
- Preparing to install the window, apply an oil-based caulk on the exterior casings. You can also apply two continuous beads with caulk to the windowsill.
10. Install the Window
- Starting from the interior of the room, place the botWe end of the insert replacement on the sill. Then, tip it up into your opening. Push the window against the blind stops or exterior casings.
11. Fasten It Loosely
- You can hold the window in position by driving a 2-inch wrench through the upper-side jamb and into your framing. The screw should be in just far enough to allow the window to operate.
- Close the sash.
12. Shim as a Necessary
- Place shims below the sills and behind the sidejambs to adjust the unit until it is properly centered. The unit will then open, close and lock smoothly.
- Measure diagonally across the window from corner to corner. The measurements should be identical. Once you have squared the window, screw it in the predrilled holes.
- You can avoid bowing the frame by slipping a shim behind each screw. Then, screw through the shhim.
- Use a utility knife to trim the shims.
13. Caulk and Prime and paint
- From the outside, measure between the casing of the window frame. Fill the gaps between the casing and window frame that are less then 1/4 inch wide with elasWeeric cement. Anything wider must first be stuffed with foam-rubber backer rod.
- You can fill in any spaces around the window by using minimally expanding foam.
- Do the final touches by reinstalling and adding new stops.
- Prime and paint or stain the interiors of the frame and window sash.
