Introduction of Pivoted Windows
A pivoted window is a type of window that can be rotated on a hinge to open in different positions. This window is usually made of a piece of glass.
This window is a kind of double-hung window which rotates on its axis and because of this, it is bigger than a regular double-hung window.
These windows are also known as “openers”. A Pivot window is more expensive than a single-hung window or casement window. There is no problem in opening the bottom sash even in rainy conditions and the top sash closes tightly when this window is closed.
What Is Pivoted Window?
Pivoted windows have a sash attached to the center of the frame as well as a normal pivot of 170 degrees around the vertical axis. There are two types of windows. Horizontal pivoted window and vertical pivoted window.
The pivoted window comes with an integral restrictor with 10 degrees or 15 degrees and has a reverse stop at 170 degrees. The uniqueness of this window is that it meets the requirement of specification and has the ability to rotate the sash in the room for cleaning.
Typical applications for this window are large open spaces in commercial buildings or in residential buildings where the design requires an unobstructed view and large window sizes.
The pivoted window is easy to reach from the inside for cleaning and maintenance as the sash can rotate 170 degrees.
There is a restrictor on the front face of the window for ease of access and it helps in draft-free ventilation when opened in pre-set ventilation. When the pivot window is completely inside the wall cavity, it is necessary to install air seals on the top so that there is no problem with a water leak.
When we open this window to one side, the top sash slides up and out of its groove so that it can rotate on its hinge to open. The window has a single sash that rotates on its hinge and allows it to swing back and forth in different positions.
Automatic pivot windows are also available that can be opened or closed using the remote. The pivot window can be fixed at the desired angle using the pivot lock. When the pivoted window is fixed at 90 it allows the maximum amount of fresh air to enter.
Mechanism of Pivot Window
The pivot window is similar to a normal casement window with other opening mechanisms. The movable part in the casement window is hung from the side of the hinges.
While the movable part in the pivot window pivots the center vertically or horizontally through the hinges mounted in the center of the frame.
When this window is opened it leaves the catch on the casement and pivots. The option of bowing to a regular casement window is not possible.
Types of Pivoted Windows
There are three types of pivoted windows depending on the design.
- Horizontal Pivot window
- Vertical Pivot Window
- Center Pivot Window
The horizontal pivot window rotates on a horizontal axis and can be unlocked to rotate 180 degrees for cleaning. The vertical pivot window rotates on a vertical axis. Vertical windows can also be unlocked for cleaning.
The pivot window frame is made from materials such as wood, composite, fiberglass, aluminum, vinyl, etc. The following are the types of pivot windows depending on the material.
1. Composite Pivot Window
A composite frame is made from a mixture of materials. The interior consists of a wooden frame with a fiber frame or a plastic group or an aluminum cladding. The composite pivot window is maintenance-free and can be repainted.
2. Fiberglass Pivot Window
Fiberglass pivot windows are expensive but durable and strong. Fiber pivot windows are about eight times stronger than vinyl pivot windows.
These windows have limited expansion and contraction so such a frame does not place undue stress on the glass. Fiber frames allow for a variety of designs, such as narrow frames.
3. Aluminum Pivot Window
Aluminum pivot windows are cheaper than other options but their insulating capacity is limited compared to other windows. Aluminum frames can be the victim of thermal breaks.
The energy capacity of such a frame can be increased by separating the inner and outer surfaces. If the aluminum frame is anodized or baked on the finish, it limits the need for further maintenance in the future.
4. Wood-Clad Pivot Window
A wood-clad frame is a wooden frame with aluminum or vinyl cladding. Wood clade fame provides excellent insulation but can be deformed or rotten if not maintained periodically. Such a frame provides wood insulating capacity with weather resistance of aluminum or vinyl frame.
5. Vinyl Pivot Window
Vinyl pivot windows are a good alternative as cheap, durable, and maintenance-free windows, as well as these windows, are excellent energy-efficient. Can’t paint this window so the color we choose for this window lasts a lifetime. A thin pivot frame is not possible as vinyl is a heavy material.
6. Glazing Pivot Window
Glazing is useful for resisting heat transfer and for adequate insulation. Energy-efficient glazing increases the thermal efficiency of the window. This window can save on energy savings over a lifetime.
Center Pivot Roof Windows
The center-pivot roof window is very important to allow light to enter the small or unusual space of the house. Sitting between 15 to 90 degrees i.e. lower ceiling they work well. Also, these windows can easily fit into a room with furniture.
The good thing about a center pivot ceiling window is that it can be placed lower on a pitched ceiling. This window is a versatile option to make maximum use of the view while sitting or standing in the room.
The handle is installed at the top of the frame to operate this window, which is designed with hinges in the center of the window. The handle has to be pulled down to open the window.
The bottom of the panel is tilted outwards and the top is tilted inwards into the room. This design works very well in a room with low ceilings as the handle can be easily accessed.
In the automatic version, the window can be run using the remote control. The automatic option is ideal for places that are out of reach of the house such as a high landing as well as a place that needs a little extra light and air.
The mechanism is locked when the window is closed. The only way to reopen a window is from inside the house so this is a great security feature.
Pivoted Window Replacement
The level of thermal insulation and weather resistance of a pivoted window depends on the window framing material. The thermal insulating capacity of this window determines the glazing of the window and the material of the window.
This is necessary to prevent heat transfer between the interior and exterior of the house. There should be sufficient weather-stripping barrier to properly seal this window.
When it comes to pivot window replacement, it is advisable to install the window keeping in mind the above information.
