A Jaali is a window or screen mesh carved into wood or stone by craftsmen. Commonly found in Islamic and East Asian architecture, it was initially developed as an architectural solution for combatting extreme heat in arid climates and regulating light.

Jaali allows light and air while minimizing sunlight and rain and cooling by passive ventilation. One of the main advantages of Jali is the ability to see across without being seen. However, it depends a lot on the size of the openings and the amount of light they transmit. These perforated screens are often used outside houses, like windows, partitions, skylights, door panels, railings, and more. These are the best to hide bathroom plumbing and ventilation systems.

For building purposes, terracotta has meaning in a world where energy, environmental and financial difficulties cannot be ignored. In this type of clay, bricks, coatings, and tiles are energy efficient and economical.
Terracotta blocks store thermal energy during daylight and release it slowly at night. It is therefore less expensive to heat the building during cold times and to cool it in hot weather. Rain screens and umbrellas made from the material have also been proven to reduce power consumption.
