A sliding window is one of the most common glass window mechanisms found in Singapore homes — from HDB flats to condominiums and landed properties. Known for its smooth operation and space-saving design, a sliding window is a durable and affordable choice for modern Singapore homeowners.
If you’re planning to replace or install a new sliding window in your home, this guide explains everything you need to know — including how sliding windows work, the different configurations available, HDB regulations, material and colour options, as well as useful maintenance tips.
What Is a Sliding Window?
A sliding window opens by gliding horizontally along a track instead of swinging outward like a casement window. This makes it an ideal choice for areas such as HDB corridors or internal windows where space is limited.
Each window set usually features two or more movable glass panels that slide smoothly on high-quality rollers. The sliding window frame is made from durable aluminium, ensuring it will not rust or corrode even in Singapore’s humid climate — making it a long-lasting and low-maintenance option for any home.
How Do Sliding Windows Work?
A sliding window operates on a track fitted with smooth-gliding rollers. The rollers allow the panels to slide left or right, enabling easy control of airflow and light.
Quality systems such as Prime Sliding Window from Ho Ho, include wind proof blocker, side seals, and middle rubber seals to reduce noise, dust, — all essential features for Singapore’s tropical weather.
Why Are Sliding Windows Popular in Singapore?
Sliding windows are one of the most popular window types in Singapore because they are practical, affordable, and perfectly suited to our living spaces. Whether you live in an HDB flat, condominium, or landed home, a sliding window offers several key advantages:
Space-efficient: No swing clearance needed — ideal for internal openings and HDB corridors facing windows.
Low maintenance: The aluminium frame of a sliding window does not rust and is easy to clean.
Bright and open: Wide glass panels allow maximum daylight and unobstructed outdoor views.
Smooth to operate: Quality roller systems ensure the panels glide effortlessly for years.
Affordable option: Among all window mechanisms, the HDB sliding window is generally the most budget-friendly to install and maintain.
Common Configurations of Sliding Windows
Different sliding window configurations suit different areas of the home. Below are the most popular designs commonly installed in Singapore homes.
a) Standard Sliding Window
The most practical and affordable option for everyday use. A standard sliding window offers a clean, modern look that makes your home appear brighter and taller.
b) Sliding Window with Top Hung
This configuration combines a top hung window above and a sliding window below. The top hung portion allows continuous airflow even during rainy days or when you’re not at home. It’s especially useful for HDB corridor-facing windows, as you can close the lower sliding section for privacy while keeping the top open for ventilation.
However, the top hung panel may be harder to reach for shorter homeowners, and using a stool or ladder to open it can be unsafe.
c) Double Section Sliding Window
A double section sliding window is another common choice for HDB corridors facing bedrooms or living rooms. It features two independent sections — top and bottom — that can be customised with different glass types. For example, many homeowners choose frosted glass for the bottom section to maintain privacy, and clear glass for the top to allow more natural light. This design offers privacy and ventilation while remaining easy to operate, as both sections slide horizontally without needing to reach upwards like a top hung window.
HDB Guidelines to Note for Sliding Windows
Before installing or replacing your HDB sliding window, it’s important to ensure your new windows meet all HDB safety requirements. These rules are designed to prevent accidents and ensure long-term safety for homeowners and the public.
Below are the key HDB guidelines for aluminium sliding windows:
Safety Devices
Every sliding window must include two self-locking safety devices made of polyethylene (2 per panel).
Install synthetic resin stoppers at the top of the window’s outer frame — a minimum of two stoppers per panel width.
Stoppers must be secured with stainless steel grade 304 screws or rivets
The bottom outer frame must use an aluminium frame with a fixed angle facing outside for extra stability.
Panel Dimensions
The width of each sliding window panel must not exceed 1200 mm
Licensed Contractor Requirement
All window installations in HDB flats must be done by a BCA-registered and HDB-licensed contractor.
Your contractor is responsible for submitting the HDB Window Permit before any work begins.
