Specifying window treatments involves a lot of small details – from the way they are mounted, operated and hemmed to the measurements inside and outside the area of the window. So it’s no surprise that there are a lot of important terms to know!
If Jabot, Lambrequin and Swag sound like made up words to describe window treatments … we assure you, they aren’t! Here are the A-Z’s of Window Treatments that will have you better prepared for your next drapery or window top treatment project:
Allowance – Additional fabric added for hems, headings, bolt loss, etc. for fabrication.
Blackout Lining- Lining fabric that has been laminated to block out light. The laminate makes the lining heaver and stiffer than standard lining. Available in 2 and 3 pass. It is most often white or cream.
Clearance – Distance from wall to back of the rod.
Directional Fabric- Fabric that has a specific orientation due to pattern, nap or weave that needs to be considered.
End Bracket – Two supporting grips that holds a drapery rod, shade or blind. The end bracket controls the amount of projection.
Fullness – Extra fabric added to the finished width of the window treatment. Example: 100” finished width would need 200” of fabric width hemmed to achieve 2 to1 or 100% fullness.
Give – Allowance added to finished drapery width to allow panels to traverse easily. General rule is 1” – 2”.
Heading – Hemmed, usually stiffened portion across the top of a drapery.
Inside Mount - Treatment is mounted inside the window frame, so that it is recessed within the window opening.
Jabot - Fabric that is folded and falls in a zigzag fashion down the sides of a treatment. Cascades are most commonly used with swags.
Kick Pleat – Pleat formed like a box pleat in reverse, so the edges of the pleat meet in the middle on the face of the treatment. Also known as an Inverted Pleat.
Lambrequin – Box-like structure typically made of wood stained, painted or upholstered with fabric. Unlike a cornice, a lambrequin continues down the sides of the window.
Master Carrier – Lead carriage on drapery hardware.
NFPA 701- National Fire Protection Association test methods for small-scale and large-scale drapery fabric vertical ﬂame tests.
Outside Mount - Treatment is mounted outside the window frame on the wall or casing surrounding the window.
Projection – Distance from the wall to the front of the drapery rod or valance board.
Return – Part of a drapery, cornice or valance that turns around the sides for a neat finish and light control.
Swag – Draped fabric folded to form pleats and a scallop shape on the bottom.
Traverse – To draw across. A traverse drapery is one that opens or closes across a window by means of a traverse rod.
Valance – Soft fabric skirt that hangs from the top of a window.
Width – Describes a single width of fabric. Several widths of fabric are sewn together to create window treatments. The term is also used when referring to the “rod width” or “finished width”.
