Sealing

Sash windows are beautiful in older buildings, but they require regular maintenance and could be susceptible to problems like cracks in putty, wet rot and drafts. It is possible to reduce energy loss and improve the efficiency of sash windows by replacing, repairing or sealing them.

Draughts are usually caused by gaps between the sash and the frame. They can also cause noise reduction and rattling. Sealing beads, specialty products, and secondary glazing can all be used to minimize the air leakage inside a Sash.

A common problem is a gap that exists between the top of the sash and the jamb frame, or the bottom of the sash and the sill. This can cause moisture to leak into the wood, rotting it and the growth of mold. The gap can be closed by caulking made of silicone or polyurethane or foam sealant.

Installing a new sash runner, or spring bronze could be required if a gap prevents the windows from opening and shutting smoothly. These are strips of bronze that are stapled or nailed into the edges of the lower sash to prevent sideways rattle. They can be purchased at DIY stores. Tubular vinyl weather-stripping is an alternative option but it can tear, and can detract from the appearance of windows.

When installing replacement runners for sash It is crucial to take full measurements of the window opening. It is best to take measurements from the top of the sash up to the horizontal centerline on the meeting rail and from the bottom sash down to the sill. These measurements can be incorporated into the new runners, which will help ensure a good fit and better operation of the window.

In older buildings the gap between the frames and sash is typically larger around the leading edge. It can be draught proofed by using a self-adhesive Vstrip, however it is essential to account for this when measuring and cutting the material.

The strip should be cut to the height of the sash with an inch extra on each side to allow movement. It should be trimmed to a square shape and then positioned so that the ends are aligned to the angle of the window sill. It is also crucial to use stainless steel screws, since brass can rust and a high-quality silicone or polyurethane adhesive.

Refurbishment

It involves lining the joining rail and sash box with traditional putty and fixing any rot damage. Re-painting the frame of the timber is also included, as well as re-double glazing Canterbury using traditional glass. A full refurbishment can also include adding draught proofing, re-attaching the sash furniture/ironmongery and replacing the parting bead (the dividing strip between the two panes of glass). It’s also recommended to install brush pile weather strip to minimize the noise of rattling.

Before you put the new window in place It is recommended to compare its metal tabs to the tabs on the old sash (see below). If they’re different sizes and sizes, the new sash will not fit into the window frame slots.

When a window is damaged it’s essential to choose between repair or replacement, since each kind of repair will require a different level of expertise and expense.

Making the window come apart starts by removing any security fittings in front of the lower sash. Then, remove the staff bead. Finally, pull out the sash at the bottom. Then, take the chains or cords on both sides, and tie them to prevent them being pulled back into the frame by the weights attached to them. Now it’s time to remove the upper sash. Unscrew the sash stops (a thin vertical strip of wood that holds the sash) and then loosen any painted-covered hardware. Reverse the sash to reveal the weight. It is a large iron or lead cylinder that is concealed inside a cavity and held by an elastic cord. To stop the sash falling into the void pierce it with an hammer and then sacrifice the weight.

After the sashes are removed clean the jambs and rails that connect them. Remove the glazing bars as well as the sash cords. Then using a utility knife take off any paint that is on the sash stop. When the sashes are back in place, reattach the stops using nails that are small enough to prevent puncturing the weight that is balancing.
