Sliding Window Singapore (HDB, Condo & Landed)

ZGH Aluminium is an HDB & BCA registered window contractor supplying and installing custom aluminium sliding windows across Singapore. HDB sliding window replacement in Singapore can start from around $1,800 for smaller 3-room resale flats and go above $3,900 for larger 5-room flats. The final cost depends on the flat type, window size, number of panels, aluminium frame, glass type and site requirements.

Sliding windows are one of the most common window types for HDB flats, condominiums and landed homes. They are affordable, practical, durable and space-saving. Their panels open horizontally along a track without swinging into the room or projecting outside, making them suitable for bedrooms, kitchens, service yards, common-corridor areas and other compact spaces. 

Each window is made to measure. Customise the panels, frame colour, tracks, glass and optional grille. ZGH manages the window works from measurement and fabrication to installation and testing.

Benefits of Aluminium Sliding Windows

Space-saving operation: The panels move sideways within the frame. This is especially useful for a compact HDB flat or a room beside a common corridor.

Simple and convenient to use: A sliding system opens and closes with a straightforward horizontal motion. Quality rollers and aligned tracks support smooth daily operation.

Flexible ventilation: Open one or more panels to adjust airflow. Wider windows can use additional panels to balance ventilation, weight and operation.

Low maintenance: The simple sliding mechanism has fewer exposed moving parts. Regularly removing dust from the tracks and wiping the aluminium frames is generally sufficient for routine maintenance.

Durable aluminium frames: Aluminium is lightweight, moisture resistant and well suited to Singapore’s humid climate. Powder coated finishes provide a neat appearance and allow the frames to complement different interior styles.

Custom privacy and daylight: Choose clear glass for views, frosted glass for privacy or tinted glass to reduce glare. Consider the room’s direction, surroundings and desired daylight.

Suitable for different properties

ZGH produces high quality sliding windows for HDB, BTO, condominium and landed properties. We assess each project according to its opening, façade requirements, access, and site conditions.

For HDB window replacement, you need a window replacement permit. The work must be done by a BCA-approved window contractor listed with HDB. ZGH Aluminium is an HDB and BCA-approved contractor and can handle the permit process before installation begins.

Sliding Window Customisation

ZGH will recommend a configuration based on how you use the room and how much of the opening you want to access. Customisation options include:

• Panel count: Select two to six panels according to the width of the opening.
• Panel proportions: Adjust panel widths for balanced movement and a cleaner overall appearance.
• Frame colour: Powder coated finish should complements the building façade.
• Glass finish: Select clear, frosted or tinted glass for your preferred balance of visibility, privacy and glare control.
• Window grilles: Add an aluminium grille when you need extra safety for children, elderly family members, or pets.
• Upper and lower sections: Use a two-tier setup if you stay near a corridor unit. Choose it when openings or privacy need separate sections.

For condominium projects, owners should check their management corporation’s renovation and façade requirements. Landed homeowners can customise larger openings, heavy duty sliding window, subject to measurement, structural surroundings and practical panel sizes.

Our Sliding Window Services Include

Dismantling and disposal of existing windows
Our installers carefully remove the existing window system and clear the dismantled materials from the work area. The removal approach is planned around the opening and site access to minimise disruption to the household.

Installation of new sliding windows
After fabrication, our team fits the new aluminium frame, installs the panels and checks the tracks, rollers, locks and seals. We test the window movement and alignment before completing the work, helping ensure that every panel opens and closes smoothly.

Submission of the HDB window replacement permit
HDB window replacement requires a permit before work begins. As an HDB & BCA registered window contractor, ZGH can submit the window replacement permit and complete the installation according to the approved requirements.

Sliding windows with grilles

An aluminium grille can be installed as a separate layer for added peace of mind. ZGH will plan the window and grille together so both remain practical to operate and maintain.

ZGH Aluminium has more than 20 years of aluminium experience, direct-factory pricing and a five-year workmanship warranty for eligible window installations.
