When it comes to choosing windows for your HDB or BTO flat in Singapore, the most common options are sliding windows and casement windows. Both are typically made from aluminium, which is durable and low-maintenance — ideal for our humid climate. But which type is best for your home?
Let’s break down the pros and cons of each type of window.
⸻
Sliding Windows
Sliding windows operate by moving horizontally along a track. They’re popular in service yards, kitchens, and bedrooms.
Pros:
1. Easy to Maintain – Simple design makes it easy to clean and operate.
2. Practical for Laundry Areas – Ideal for service yards where you need to hang clothes or access poles.
3. Wider Viewing Space – Offers an unobstructed view, perfect for enjoying natural light.
4. Wide Panel Option – Each panel can be up to 1200mm wide, as per HDB guidelines.
Cons:
1. Water Accumulation – Tracks may trap rainwater if not properly maintained.
2. Lower Noise Insulation – Gaps in the sliding mechanism can let more sound in.
3. Limited Design Options – Not suitable for custom or odd-shaped windows.

Casement Windows
Casement windows are hinged on the side and swing outwards. They’re commonly used in bedrooms and living rooms for better airflow.
Pros:
1. Saves Space on Parapet – Great for tight spaces, especially in BTO units.
2. Better Sound Insulation – Provides a tighter seal, reducing outside noise.
3. Improved Water Resistance – Hinged design offers better protection against rain.
4. Sturdy Build – Each panel can go up to 700mm wide, in line with HDB standards.
Cons:
1. Requires Effort to Operate – Opening and closing may need more force.
2. Not Corridor-Friendly – Can’t be used along corridors due to safety regulations.
3. More Difficult to Clean – Especially if placed in hard-to-reach areas.
4. Blocked View – Middle frame (or “bone”) can obstruct the scenery.
