How to install new window frames in The Netherlands

1. Window Replacement Parts

Types and styles of Replacement Windows

Unlike full-frame windows, which are designed for new construction, replacement windows are made to fit into existing window openings. There are many standard sizes available, including those that are as narrow as 11 1/2 inches to as wide at 68 inches. They also come in wood, vinyl and fiberglass.

There are three types of replacement windows that you can choose from: sash replacement kits, insert replacements and full-frame units. Sash-replacement kits--what We found on the Newton house--give an old window frame new movable parts, including jamb liners and sash. The liners are fastened to the side jambs of the window opening, then the sash are slipped in between.

These insert replacement windows cannot be used if the existing frame is not square or level. An insert replacement window is a fully assembled and ready-to install window. An insert replacement window is sometimes known as a pocket window. It slips into an existing opening and is then attached to the old sidejambs. The glass area will shrink slightly because of the addition of liners and jambs.

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 are the only alternative if the original window frame, sill and jambs are damaged. These must be removed from the window opening so that it can be reassembled.

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's how to do it.

• Measure the inside width from the old window frame jamb by jamb. Do this in three places: across its top, middle, or botWe. The smallest measurement should be taken.
• 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. Record the smallest measurement.
• You can check the squareness by measuring diagonals from corner-to-corner. Both dimensions should be equal. Don't worry about if your frame isn't square by 1/4" or less. You can easily shim it to fit. You may need to adjust the frame for any additional dimensions. A full-frame replacement is necessary if the frame is so outof whack that it would not look right with a square replacement.
• Use an angle-measuring device to determine the slope of your sill. Some replacements include a variety of sill angles.

3. Grab the Sash

• Remove the old sash from your window frame. Most cases, the inner wooden stops will need to be removed or pry out to remove the lower part of the sash. You should be very careful when reinstalling the stops. They break easily.
• Next, take out the parting beads to free the upper sash. Beads won't appear on windows with sash-replacement systems. Just press down on the jamb liner and pull the top of your sash forward.
• Next, turn one side of your sash upwards to remove it from the jambliners.

4. Jamb Liners to be Removed

• If the window frame was fitted with vinyl or aluminum jamb liners, use a flat bar to pry them free. In the case of an original window, remove any remaining wooden stops from the window frame.
• Keep the exterior and interior casings intact.

5. Prep the Frame

• You can scrape away any loose or blistered paint, and then patch any cracks or holes with exterior-grade wood glue such as those from Minwax or Elmer's.
• After sanding the jambs, prime and paint the surfaces.

6. Remove the Old Sash Weights

• If the original sash weights are still in place, take this opportunity to remove them from their pockets and insulate behind the window frame.
• Pull out the weights by unscrewing each side jamb's access panel.

7. Prep for Insulation

We love polyurethane foam because it blocks more air than fiberglass insulation.

• Use only low-pressure foam that is minimally expanding for windows and doors. Anything else will bow the frames, preventing the sash's from functioning.
• First, remove any fiberglass from 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. Next Spray the Foam

• The expanding foam should be pushed into the holes until the foam begins to ooze. (We are using a commercial system, but you can do the same job with foam from a can, like Dow's Great Stuff.)
• Spray foam in the sash-weight pockets at the sides jambs. Let the foam dry for at least six hours before removing it flush.

9. Caulk the Opening

• In preparation for installing the window, apply an elasWeeric caulk to the exposed inner face of the exterior casings or to the blind stops on the top and sides of the frame. You can also apply two continuous beads with caulk to the windowsill.

10. Install the Window

• Set the insert replacement botWe onto the sill. Once it is placed, flip the insert up into the opening. Press the window tight against the exterior casings or blind stops.

11. Do not fasten it

• Hold the window in place with one 2-inch screw driven loosely through the upper side jamb and into the framing. The screw should not extend beyond the window's functionality.
• Close and lock the sash.

12. Shim as Necessary

• You can adjust the unit by placing shims behind the side jambs and under the sill until it is centered. It will then open, close, and lock smoothly.
• Measure the window diagonally from corner to corner; the measurements should be the same. After the window has been squared, screw it in position through the holes.
• To avoid bowing the frame, slip a shim behind the jamb at each screw, then screw through the shim.
• Use a utility knife to trim the shims.

13. Begin Caulk and Prime and Painting

• From the outside, measure between the casing of the window frame. Fill gaps smaller than 1/4 inch with elasWeeric calk. Fill any gaps wider than 1/8 inch with elasWeeric caulk.
• Place minimally expanding foam around the windows on the inside.
• Next, reinstall the stops and add new ones.
• Prime and paint or stain the interiors of the frame and window sash.
