Components

Parts that make up a Sash Window.1. Top Rail: The top horizontal framing member of a sash. Rebated (SEE GLAZING BAR) on the outside.2. Box Frame: Sometimes referred to as a ‘jamb’, the main box frame consists of three TIMBER LININGS.3. Sash Cord: The waxed type is best- it runs over the PULLEY WHEEL and holds the WEIGHTS. Spiral Balancers are an alternative.4. Weight Pocket: The WEIGHTS hang in the pockets created by the TIMBER LININGS on each side of the window.5. Parting Bead: A long, narrow vertical seal that fits in the BOX FRAME to form separate channels for the upper and lower sashes to run in, and holds the top sash in place.6.Staff Bead: A moulded piece of timber made up of four sections, pinned around the BOX FRAME, which aids airtightness when draught proofed and also holds the bottom sash in place.7. Meeting Bars/Rails: The horizontal framing members which meet the two sashes together in the middle. Their adjoining faces are bevelled so they close together tightly.8. Stile: Vertical side framing member of a sash — there is one each side.9. Apron: A decorative panel or cladding beneath the window. Not on all sash boxes.



Components continued 10. Box Cill: A horizontal bottom section of the frame fitted internally at the base of the sashes. Shaped so that water flows away to the outside.11. Bottom Rail: The bottom horizontal framing member of a sash.12. Weight: A pair of lead weights hung on the SASH CORD counterbalance each sliding sash. The sash and weights must weigh the same.13. Wag Tail: A strip of timber inside the BOX FRAME that separates the WEIGHTS. Also known as a ‘parting slip’.14. Timber Linings: The sections that form the casings of the BOX FRAME – which must be hollow to house the WEIGHTS – are made in three parts: the ‘outer’, ‘inner’ and ‘pulley’ linings.15. Pulley Wheel: A pulley mortised into the top of the PULLEY LINING; the SASH CORD passes over it to counterbalance the WEIGHTS.16. Glazing Bar: A vertical or horizontal framing member that divides the panes within the STILES and RAILS. Each rebated – a cut which forms a groove – to hold the single-paned glazing or on replacement bars double glazing. Georgian sash windows have ‘six over six’ panes, but other configurations are common across London.17. Soffit Lining: The windows head is made up of the main inner and outer TIMBER LININGS as well as a separate soffit lining; glued triangular blocks provide strength.
