How to replace your window frames in The Netherlands

1. Window Replacement Parts

Types and styles of Replacement Windows

Full-frame windows are meant for new construction. Replacement windows fit in existing window openings, unlike full frame windows. 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 basic types of replacement windows: sash kits, insert replacements, and full-frame units. We discovered the sash-replacement-kits on the Newton home. These kits give an old window frame new, movable parts including jamb liners. The liners can be attached to the sides of the window opening and the sash slipped between.

To make these work, your existing window frame must be square and level. An insert replacement window consists of a fully assembled window in a ready-to-install secondary frame. Sometimes called a pocket window, an insert replacement slips into the existing opening and is then fastened 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 part of the window-replacement procedure is not until installation day. This is when you measure the existing window frame in order to choose the right replacement unit. This is how it works.

• Measure the inside width from the old window frame jamb by jamb. Do this in three places: across its top, middle, or botWe. Record the smallest one of the three measurements.
• Next, measure how high the frame is from the top edge of the sill to below the head jamb. Do this in three places: the left jamb at the middle, the middle and the right. Record the smallest measurement.
• You can check the squareness by measuring diagonals from corner-to-corner. The 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. If the frame is so out of whack that a square replacement wouldn't look right, you'll need a full-frame replacement.
• 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 thing you need to do is remove the old window frame sash. To remove the lower section of the sash in most cases, you will need the wood stops inside the window frame to be removed. If you plan to reinstall the stops (or if they are already removed), be careful. They can easily break.
• Next, remove the end caps to release the upper sash. There won't be beads if your windows have sash-replacement kit. Simply press down on jamb liners to pull the top edge of the sash up.
• Turn the sash towards the sky and lift it off the jamb liner.

4. Jamb Liners - Get Out of There

• Use a flat bar to remove vinyl jamb liners or aluminum jamb liner from the window frame. For original windows, remove all wooden stops.
• The exterior and interior casings should be left intact.

5. Prepare the Frame

• All loose and blistered coatings should be removed and any cracks must be filled with an exterior-grade wood epoxy such as Minwax and Elmer's.
• Finally, sand and prime the surfaces.

6. Get rid of the old Sash Weights

• 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.
• Unscrew the access panel on each side jamb and pull out the weights.

7. Prep for Insulation

We like polyurethane insulation, as it's more effective in blocking air than fiberglass insulation.

• Low-pressure, minimally expanding foam for windows or doors is best. Anything else can bow the frames and prevent the sash of 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. Next Spray the Foam

• Shoot the expanding foam into the holes until it begins to ooze out. (We are using the commercial system. However, you can use foam from cans like Dow’s Great Stuff to accomplish the same task.
• Spray foam on the pockets of sash weight in the side jambs. Let the foam dry for at least six hours before removing it flush.

9. Caulk The Opening

• Before installing the window, you should apply an elasWeeric adhesive caulk to the outer casings or blind stops at the top and sides. 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. The window should be pressed against the blind stops or exterior casings.

11. You can 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 and lock the sash.

12. Shim is essential

• 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 you have squared the window, screw it in the predrilled holes.
• To avoid bowing your frame, slide a shim at each screw's jamb, then screw through that shim.
• Trim the shims flush with a utility knife.

13. Time To Caulk, Prime and Paint

• Measure the gap between the casing and the frame from the outside. Fill gaps smaller than 1/4 inch with elasWeeric calk. Any gaps larger than 1/4 inch must be filled with foam-rubber backing rod.
• You can fill in any spaces around the window by using minimally expanding foam.
• Finish up by reinstalling the stops or adding new ones.
• Then prime and paint, or stain the interior of the window sash and frame.
