HDB Window Replacement Guidelines in 2025
Introduction: If you're planning to replace your windows in your HDB flat in Singapore, it’s essential to understand the HDB window replacement guidelines to ensure your renovation project complies with regulations. Whether you're looking to upgrade to modern sliding windows, install Bi-fold windows (Slide and Fold Windows), or simply refresh the look of your home, knowing the rules for window replacements can save you time, money, and potential legal headaches. In this blog post, we’ll guide you through the key HDB window replacement guidelines for 2025 to help you make informed decisions.
Why Replace Your Windows in an HDB Flat?
There are several reasons why you might consider replacing your windows, including:
- Improved Aesthetic: Modern windows can enhance the overall look and feel of your home.
- Increased Safety: Outdated windows can be less secure, while newer models offer advanced locking mechanisms.
- Enhanced Ventilation: Modern designs like bi-fold (Slide and Swing Windows) or Casement windows allow for better airflow in your home.
Key HDB Window Replacement Guidelines for 2025
1. Obtain Prior Approval from HDB
Before replacing any windows, HDB approval is required. This ensures that the new windows comply with HDB's safety and design standards. If you engage MAG, we will help to submit a renovation application to HDB for approval before proceeding with the installation.
- Approval Requirement: Whether you are replacing windows with the same design or opting for a completely new style (like sliding windows or Slide and Fold windows), HDB’s approval is mandatory.
- Window Types Allowed: HDB typically approves aluminum windows for replacements, provided they meet the required specifications.
2. Materials and Window Types
While HDB allows window replacements, they are strict about the materials and types of windows used. Here are some of the common options that meet HDB regulations:
- Aluminum Windows: The most common and affordable option, known for being lightweight, durable, and resistant to corrosion.
- Sliding Windows: Ideal for maximizing natural light and ventilation while maintaining space efficiency.
- Casement Windows: Hinged windows that open outward, providing good ventilation and security.
- Slide and Fold Windows (Bi-Fold Windows): a modern window design that allows multiple panels to slide and fold neatly to one side, creating an expansive opening.
Note: Wooden windows or windows with non-HDB approved materials (such as glass or steel) are typically not allowed.
3. Compliance with Size and Design Regulations
When replacing windows, the design and size must align with the existing structure and comply with the HDB design specifications. This includes:
- Maximum Size: The replacement window must not exceed the maximum size allowed by HDB for the particular type of window in your flat.
- Aesthetic Consistency: Windows must maintain a similar aesthetic to the original design, ensuring consistency across the block and community.
- Safety Considerations: Windows must meet safety standards and cannot project beyond the edge of your unit.
4. Hire an Approved Contractor
Only HDB-licensed contractors are allowed to carry out window replacement work. These contractors are familiar with HDB’s renovation regulations and can ensure that the installation meets the necessary standards.
Ensure the following:
- The contractor must be licensed by HDB for window replacement works.
- The installation must adhere to the approved design and size.
5. No Encroachment into Common Areas
Replacement windows should not extend into the common areas or obstruct the views of neighboring flats. This means that your new window design should remain within the boundaries of your unit and cannot interfere with external aesthetics. For this reason, only Sliding and Louvre Windows are permitted along the common Corridors. Slide and Fold (or Bi-Fold Windows) are permitted so long as they fold inwards into the house and Approval is granted from HDB.
6. Adherence to Safety Standards
HDB requires that all replacement windows meet safety standards to prevent accidents, especially in high-rise buildings. The windows should be designed to withstand strong winds, prevent unauthorized access, and limit accidental falls.
- Secured Locks: Windows should be fitted with proper locking mechanisms.
- Safety Glass: Some types of glass that are below 1m height from ground is needed to be safety-rated (Laminated Glass) to avoid breakage.
