What Is a Two Tier Sliding Window?
A two-tier sliding window is a practical and space-saving option. It is designed especially for HDB corridor-facing flats. It has two layers of sliding glass panels. The top and bottom can open separately. This gives you control over airflow and privacy.
This design is ideal for households that want fresh air without compromising on privacy. The window has a strong aluminium frame that lasts a long time. You can choose clear or translucent glass. This lets in natural light while keeping your home comfortable and private.
What Are the Benefits of a Two Tier Sliding Window?
- Privacy with Ventilation – For HDB flats facing a common corridor, it’s often difficult to balance airflow and privacy. With a two-tier sliding window, you can keep the bottom part closed for privacy. You can open the top panel for ventilation. This lets fresh air in without showing the interior of your home.
- Ideal for Corridor-Facing Homes – This design slide horizontally prevents obstruction along walkways and is an excellent choice for maintaining both comfort and safety in shared spaces.
- Custom Glass Options – Choose between clear glass for maximum brightness or translucent glass for added privacy. Both options provide excellent natural lighting while reducing glare and visibility from the corridor.
- Durable and Easy to Maintain – Built with high-quality aluminium frames and powder-coated finishing, these windows are designed to withstand Singapore’s weather conditions. The smooth sliding mechanism ensures long-term use with minimal maintenance.
