One of the key benefits of rectangular shaped windows is their simplicity and versatility. They have a clean uncluttered appearance that can enhance the aesthetics of any home. They are also easier to install, which can help to reduce construction costs and time.


Rectangular shaped windows come in a wide range of sizes, from small accent windows to large picture windows which makes them suitable for various applications, from providing natural light and ventilation to creating a focal point in a room.


Another benefit of rectangular shaped windows is the variety of opening functions in which they are available. Rectangular windows can easily be installed in any room of the house, including kitchen, living room, studies, bedrooms  and insure smooth operation and aesthetic appeal.

Recommended products

Sidehung window - outward opening and perfect for fire egress routes

Sidehung windows, also called casement windows, are a type of window that opens outwards on hinges attached to the side of the window frame. They are a popular choice for houses as they provide good ventilation and the best “clear opening” area for the size of the frame.



Top-guided window - for excellent ventilation

Top guided windows provide particularly good ventilation, as fresh air is able to enter from both above and below. Also they are very easy to operate.



Fixed window - unobstructed views and natural daylight

Fixed windows, also known as picture windows, are windows that cannot be opened or closed. They are designed to provide unobstructed views and allow natural light to enter a room.
