Once air conditioning became popular, auto makers stopped putting in the vent windows, they saved money on parts and tooling and made cars look sleeker and function better with improved aerodynamics. The first modern car to not use vent windows was the 1966 Buick Riviera.
Although the front venting windows "provide unmatched ventilation, air turbulence and leakage outweigh the benefits". As automobile air conditioning became more popular, front window vents disappeared by the 1980s.
The vent window was hinged so that it could be rotated outward and could angle from slightly open to about a 45 degree angle. The purpose was to catch the air flow and direct outside air onto the passengers inside the car.
By the 1940s, new glassmaking procedures made it possible to produce panes that were nearly perfectly flat, and no longer had the wavy characteristics associated with antique glass. The hot new process floated molten glass on a bed of molten metal, which is where the name float glass comes from.
Power windows have become so common that by 2008, some automakers eliminated hand crank windows from all their models.
Casement windows, a style that hinges open to the side with a crank, are sometimes thought of as outdated or old-fashioned. But this could not be further from the truth. Homeowners everywhere are re-embracing casement windows for a number of reasons.
But father time, or, at least, father progress, is starting to catch up with the Wrangler, which is finally losing its manual crank-handle windows (as does the 2025 Gladiator). It's probably a bit of a reach to say that the Wrangler JL is a stone-age vehicle.
The earliest type of glass in America was called Crown or Table glass. This glass was blown into a ball, cut open and spun. These circular pieces of glass were then cut and are identifiable by the circular striations in the panes of glass. This is very early glass, most common before 1800.
However, their popularity was not to last. By the start of World War One hinged casement windows, (windows that opened out horizontally) began to become available and the popularity of sash windows declined. This decline continued throughout the interwar years and after the second world war.

The cost of quarter glass and side window replacement can vary significantly based on your vehicle's make and model, glass type, and location. In general, quarter glass replacement is less expensive than side window replacement. This is because quarter glass is smaller and less complex to replace than side windows.
Historically, operable transom windows above doors played a role in the heating and cooling in a home. Operable transoms have sashes that can be opened or closed to help regulate the temperature in a room when the door is closed.
Why Are They Called 'Witch Windows'? Local lore says witches can't fly diagonally, so having a crooked window would prevent them from getting into your home. Less commonly, people also refer to witch windows as coffin windows, crooked windows, lazy windows or Vermont windows.
1990/91Suburban and Grand Wagoneer were the Last to have wing windows.

What is quarter glass? Also called a valance window or vent glass, a quarter glass window is a side-facing window on a vehicle that is significantly smaller than the standard passenger windows and often serves as an extension of the passenger window either above the rear wheel or next to the side-view mirrors.
Unfortunately, original timber sash windows commonly reach a stage where they need to be replaced. As timber is a natural material, time and weathering can cause a variety of different issues, such as rotting, peeling, warping and cracking.
Sash or Hung Windows
They could be horizontal single- or double-hung windows or vertical sliding sash windows. Many old double-hung sash windows include counterbalancing weights on a rope or chain. The weights are hidden in the window frame or a small box. Most old hung or sash windows have wood frames.
Sash windows are often made from timber, which is typically more expensive than uPVC or aluminium. Timber provides an authentic look that complements period properties, but it does require more maintenance. Some modern sash windows are available in uPVC, offering a lower-cost alternative.
You may have noticed that some of our old homes have bricked up or filled in windows. Some properties were built in such a fashion to balance the look of a building but for many their windows were filled in to avoid paying a tax that was introduced in 1696.
Mould is a fungus which can grow on almost any surface where moisture is present. The spores are present in the air and when they meet with moisture they grow and multiply. The biggest cause of mould around windows is condensation.
Pane – A single sheet of glass. Sash – The vertical and horizonal moveable parts of the window that contain the glass.
The last vehicle that was recorded to run on a carburetor instead of a computer was the 1991 Oldsmobile Custom Cruiser. The Custom Cruiser was a station wagon that sported a Chevrolet 350 V8 engine.
The Jeep's previously optional power windows and door locks are now standard fare. Whatever cost increase these represent on Jeep's end are probably more than made up for by the streamlined trim structure and reduced build complexity—no more producing different doors for different Wranglers.
Now practically all cars use disc brakes on the front wheels, and many use disc brakes on all four wheels. In the United States, the Jeep CJ-5 (manufactured by AM General) was the final automobile (produced for the United States Postal Service) to use front drum brakes when it was phased out in 1986.
