Fenestration Defined

Fenestration Defined

Fenestration refers to the design and construction of openings in a building's envelope, such as windows, doors, skylights, and curtain walls. These openings provide light, ventilation, and views to the outside, while also serving to regulate the indoor temperature and to control the amount of heat and light that enters the building. The term "fenestration" comes from the Latin word "fenestra," which means "window." The term is used in architecture, engineering, and construction to describe the arrangement, design, and performance of the windows, doors, and other openings in a building's envelope. The science of fenestration involves the study of how these openings affect the building's thermal performance, energy efficiency, and indoor environmental quality.

Further more, fenestration security refers to the measures taken to protect a building from unauthorized entry through its windows, doors, and other openings. The security of fenestration products is a critical concern for building owners and occupants, as these openings can be vulnerable to forced entry, theft, and other forms of crime.

Here are some common measures used to enhance the security of fenestration products:

  1. Locking systems: Windows and doors can be equipped with locking systems that provide a physical barrier to entry. Examples include keyed locks, deadbolts, and sliding bolt locks.

  2. Laminated glass: Laminated glass is made by sandwiching a layer of plastic between two layers of glass. It is more resistant to breakage than regular glass, making it a good option for security-sensitive areas.

  3. Security film: Security film is a clear plastic film that is applied to the surface of existing windows. It helps to hold the glass in place if it is shattered, making it more difficult for an intruder to enter the building.

  4. Window bars: Window bars are metal bars that are installed on the interior or exterior of windows to prevent unauthorized entry.

  5. Security screens: Security screens are mesh screens that are installed over windows and doors to prevent the entry of intruders.

  6. Smart locks: Smart locks are electronic locks that can be controlled remotely using a smartphone or other device. They can be programmed to lock and unlock automatically at certain times, and they can provide real-time notifications if someone tries to enter the building.

These are just a few examples of the many types of fenestration products available. The selection of the appropriate fenestration products will depend on factors such as the location and orientation of the building, the climate, and the desired level of energy efficiency and indoor environmental quality.
