How to install new windows frames 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 come in a wide range of sizes from as small as 11 1/2 inch to as large as 68 inch and can be ordered in wood or vinyl as well as fiberglass and vinyl-clad wooden.There are three basic types: insert replacements or sash kit replacements. The Newton house's Sash-replacement Kits were what We discovered. They give an old window frame new parts, including jamb liner and sash. The liners attach to the side jambs at the window opening. After that, the sash is slipped between them.
These insert replacement windows cannot be used if the existing frame is not square or level. An insert replacement window is made up of a fully assembled, ready-to-install window. Insert replacements are sometimes called pocket windows. They fit into the existing opening, and then attach to the old side jambs. The glass area may be smaller because you are adding new jambs/liners.
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 only available if the window frame, sill or jambs have rotted. These must be removed from the window opening so that it can be reassembled.
2. Calculating Replacements
The most crucial step in window-replacement is the one that happens before installation day. Measurements of your existing window frame are important to ensure you order the right size replacement unit. Here are the steps.- Start by measuring the inside width of the old window frame, jamb to jamb, in three places: across the top, middle, and botWe. Note the smallest measurement.
- Next, measure from the top end of the sill up to the underside and height of your frame in three places. These are the left, middle, and right jambs. Take the smallest measurement again.
- Check the squareness of the frame by measuring the diagonals from corner to corner. The two dimensions should be the same. Don't worry if the frame is not square by 1/4 inch. The replacement can be shimmed to make it fit. Anything more may require adjustments to the frame. You will need a replacement for the whole frame if your frame is so out-of-whack that a replacement in square would look wrong.
- 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 take the old frame and sash off the window. In most cases, you'll need to pry off or unscrew the interior wooden stops to remove the lower sash. If you are going to reinstall them, be careful. They are easily broken.
- Next, remove the parting beads from the upper sash. You won't find any beads on windows that were fitted with sash replacement kits. Just press down on the jamb liner and pull the top of your sash forward.
- Now pivot one end of the sash toward the top to release it from the jamb lines.
4. Jamb Liners - Get Out of There
- To remove vinyl or aluminum jambliners from the window frame, you can use a flatbar to pry them out. Remove any wooden stops that may remain from an original window.
- Be sure to keep the exterior and inner casings intact.
5. Prep the Frame
- Remove all paint that is loose and blistered and use an exterior-grade wood paste such as Minwax or Elmer's to patch any cracks.
- Then sand the jambs smooth, and prime and paint the surfaces.
6. The Old Sash Weights Must Be Removed
- If the original sashweights are still in their place, use this opportunity to take them out of their pockets and insulate the frame behind the window.
- Pull out the weights by unscrewing each side jamb's access panel.
7. Prep for Insulation
We prefer polyurethane foam to fiberglass insulation because it is more effective at blocking the air.- 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, take out any fiberglass material that is still in the weight-bearing pockets.
- Next, drill three holes measuring 3/8 inches in diameter at each end. One in the center. Then, run the screws down through the sill to reach the head jamb.
8. Begin To Spray the Foam
- To get the foam to expand, shoot it into the holes. (We uses a commercial system. But foam from a can like Dow's Great Stuff can be used to do the same thing.
- Spray foam into the side jambs to seal the sashweight pocket pockets. Allow excess foam to set for at least 6 hours. Once it has hardened, cut or break it flush before you replace the sashweight pocket panels.
9. Caulk the Open
- To prepare for the installation of the window, apply an elastic caulk to either the exposed outer face of the exterior casings of the frame or the blind stops on its top and sides. Also apply two continuous beads of caulk along the windowsill.
10. Install the Window
- Start by working from the inside of the room. Place the insert replacement's botWe on the sill and then tip it into the opening. Push the window against the blind stops or exterior casings.
11. Secure It Loosely
- One 2-inch screw should be used to hold the window in place. It should be driven loosely through both the upper side jambs and into the framing. The screw should reach just enough to allow the glass to operate.
- Lock the sash and close it.
12. Shim is a must
- 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, corner to corner. Once the window is squared up, screw it down through the predrilled holes.
- To avoid bowing your frame, slide a shim at each screw's jamb, then screw through that shim.
- With a utility knives, trim the shims to the desired length.
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. Any gaps larger than 1/4 inch must be filled with foam-rubber backing rod.
- 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.
