Witch window

Witch window is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Witch window rather than just read about it. In short: In American vernacular architecture, a witch window (also known as a Vermont window, among other names) is a window (usually a double-hung sash window, occasionally a single-sided casement window) placed in the gable-end wall of a house and rotated approximately 1/8 of a turn (45 degrees) from the vertical, leaving it diagonal, with its long edge parallel to the roof slope. This technique allows a builder to fit a f…

Key takeaways

  • Witch window belongs to chemistry; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Witch window to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Witch window from memory before moving on to harder problems.

Reference excerpt

In American vernacular architecture, a witch window (also known as a Vermont window, among other names) is a window (usually a double-hung sash window, occasionally a single-sided casement window) placed in the gable-end wall of a house and rotated approximately 1/8 of a turn (45 degrees) from the vertical, leaving it diagonal, with its long edge parallel to the roof slope. This technique allows a builder to fit a full-sized window into the long, narrow wall space between two adjacent roof lines, where a window would not otherwise fit. Witch windows are found almost exclusively in or near the U.S. state of Vermont, generally in the central and northern parts of the state. They are principally installed in farmhouses from the 19th century, and can be found less frequently in new construction.

Etymology The name "witch window" appears to come from a folk belief that witches cannot fly their broomsticks through the tilted windows, although it seems unlikely that the tale was taken seriously. The windows are also known as "coffin windows"; it is unclear if they were used for removing a coffin from the second floor (avoiding a narrow staircase), or if the odd placement on the wall were reminiscent of a coffin. Either explanation seems far-fetched. The windows are also known as "Vermont windows" for their distribution and as "sideways" or "lazy windows" for their orientation.

Construction Dormer windows are unusual in Vermont, particularly in older construction; windows are mostly placed in walls. When a house is expanded, for example with a kitchen wing or an attached shed, there may be very little wall space available in the gable end in which to put a window, which may be the only window available for an upper floor room (if there is no dormer—adding a dormer to an existing roof is problematic, as it involves puncturing the roof membrane). The solution is to rotate the window until its long edge is parallel to the nearby roof line, to better maximize the space available for a window. Thus, not only is the window area (and thus incoming light and ventilation) maximized, but building or buying a custom window is avoided. An alternative explanation for the orientation of the window is that getting at least one corner of a window up as far as possible in the interior of the house allows hot air (which rises to the top of the room) to escape on summer afternoons. However, this reasoning seems suspect, as Vermont is not as hot as many other locations, where the windows are not ubiquitous. If heat escape were the goal, diagonal windows could be placed in other walls as well. The slanted orientation of the window can complicate the placement of the siding (such as clapboards) on the wall in which the window is hung, because if the siding is horizontal, it will meet the window frame at an acute angle, complicating both the cutting of the siding and the waterproofing of the frame-siding joint. One solution is to orient all of the siding on the wall so that it is parallel with the window frame.

Product placement The Weird Window Brewing company, based in South Burlington, Vermont, was named for witch windows. One of the windows is depicted in the brewery's logo.

Worked examples

Example 1 — a first encounter with Witch window

Start with the simplest possible case. Write down what Witch window claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Witch window before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Witch window ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Witch window

In research
Witch window appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Witch window in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Witch window is common in secondary-school and first-year university syllabi. It links to neighbouring topics American witchcraft, Architectural elements, Superstitions of the United States, so understanding it makes those chapters shorter.
In everyday life
Look for Witch window outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Witch window matter?

Because it connects several chemistry ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Witch window?
