uPVC Louvre Features

uPVC Louvre windows are sought after for their aesthetic appeal. In place of glass, the opaque nature of the louvres gives you additional privacy, ventilation or add a certain character to your home.

Commonly used in outdoor spaces, generator and pump rooms, louvres can be either fixed at a 30° angle to block out the sun while providing ventilation, or fully closed up to enhance privacy.

With a wide range of colours, styles and finishes to suit any design aesthetic, uPVC Louvres makes an interesting addition to any home or building.

Adjustable Glass Louvre Features

One of the main benefits of our UPVC Louvre Windows is that they allow for superior ventilation and airflow, which is essential in Singapore's tropical climate.

The angled design of the louvres allows for precise control over the amount of air entering the space, making it easy to adjust the ventilation based on your needs. This helps to maintain a comfortable indoor temperature and improve indoor air quality.

Remember the days in school with classrooms having ceiling fans and louvred windows all around? The reason for adjustable glass louvres was to fully ventilate the hot room, without having the window stick out to the corridor.
