Jalousie windows are louvered glass panels installed to enclose residential and commercial areas. They are composed of parallel glass, acrylic, or wooden louvers set in a frame. The louvers are joined onto a track so that they may be tilted open and shut in unison to control airflow, usually by turning a crank. The windows are designed through a combination of popular hand-cranked glass, aluminum, and screen window. They are commonly used in areas in need of more light and ventilation. Jalousie windows maximize natural ventilation by allowing airflow through the entire window making them ideal to mild- winter climates. They allow full ventilation even in stormy driving rains; they create some architectural interest with their strong divisions of light, and generally create an iconic ambience in any sunroom they grace.
Jalousie windows have the ability to be left at least partway open in most heavy rains, maintaining desirable ventilation whether a sun shower or prolonged tropical storm.
Jalousie windows work in the following manner;
The horizontal slats are layered on top of one another, similar to shingles or siding. The bottom of the slat above it covers the top of the bottom slat and the cycle continues all the way up. A crank opens the slats. As the crank is turned, the bottom of the hinged slats tip up and out creating an opening. Most can become fully horizontal creating a nearly unobstructed view of the outdoors. Most of these windows make use of glass panels, especially the modern options, but some use aluminum panes, or other solid materials to create a more durable window. These solid panes can still both ventilate and create a view because of the way they open.
Jalousie windows have the following features that make them ideal for residential and commercial applications. This includes;
1. They allow full length view and ventilation
2. Jalousie windows have solid vinyl thermal-wielded for strength and seal to provide a lifetime of attractive low maintenance beauty and performance.
3. They are intruder resistant such that when the window is closed it cannot be pried open from the outside.
4. They are attractive with high security hardware, which includes corrosion resistant components.
5. They have ultra-violet resistant polypropylene slat holders for added strength and durability.
6. Jalousie windows have no exposed operating metal parts for maximum corrosion resistance.
BENEFITS OF JALOUSIE WINDOWS
1. Useful during light rain
Like an awning window, the slats of a jalousie window help repel rain and keep the weather out, allowing one to bring in the storm’s cool air without soaking the floors and other surfaces around the window.
2. Enhaced airflow.
Jalousie windows allows more air flow by making use of the entire opening unlike double hung or single hung windows which can only have half the space open at a time.
3. Simple repairs.
Jalousie windows are easy to repair and cost effective because one needs to replace the damaged slat. When a section of a jalousie window breaks, one unhooks that section and put a new one in.
4. Versatile decorating options.
The slats of a jalousie window are replaceable with different types of glass and even non-glass materials like aluminum or wood. It is easier to change the look and function of this type of window than it is a full plane window type.
DISADVANTAGES OF JALOUSIE WINDOWS
1. Less water resistance
Jalousie windows do not hold out the rain snow and wind like the one solid windows do. This is due to the many openings they have which are not sealed or secured as well as a double-hung or casement window.
2. Poor insulation.
Due to their numerous sections, they have too many gaps to effectively seal and keep a home nice and warm.
In conclusion, jalousie window has proven to be the most versatile and functional window yet. Its design efficiency and security has continued to advance. If one is considering adding jalousie windows to his it is important to take into consideration of his climate, expectations for the space and security features.
