Window grilles are a common feature in Singaporean homes, providing security while complementing the overall design. With options ranging from aluminium and wrought iron to nearly invisible grilles, homeowners can choose a style that fits their space.
Finding the right installer, however, is just as important as selecting the material. A well-installed grille ensures durability, safety, and a polished look. To make your search easier, we’ve put together a list of trusted window grille installers, known for their craftsmanship, reliability, and fair pricing.
Are Window Grilles Mandatory in HDB Flats?
In Singapore, HDB does not mandate window grilles for all flats, but installation may be required in certain cases. Families with young children are encouraged to install them, particularly in high-rise units, to prevent falls. Some HDB flats undergoing renovation may also require window grilles for safety compliance.
For rental flats, the Housing & Development Board may have specific guidelines on the design and materials used. If you plan to install or replace your window grilles, ensure they comply with HDB regulations, especially regarding approved materials and aesthetics.
When Do You Need Approval?
- DBSS flats or executive condominiums require prior approval from estate management.
- Standard HDB flats generally do not require approval unless external aesthetics are affected.
- If hiring a contractor, ensure they are HDB-licensed to avoid compliance issues.
Why Install Window Grilles?
Even though window grilles aren’t mandatory, they provide essential safety benefits, particularly for households with children, elderly family members, or pets. Many homeowners also install them for added security against intrusions, especially for ground-floor or lower-level units. Additionally, grilles help prevent accidental falls, making them an important feature for high-rise apartments and balconies.
For those concerned about aesthetics, invisible grilles are a popular choice, offering protection without obstructing views or compromising natural light. They blend seamlessly with modern interiors while maintaining functionality and security.
In short, while you don’t have to install window grilles, they are a practical, cost-effective, and widely used feature in Singaporean homes for both security and peace of mind.
What Are the Different Types of Window Grilles, and How Do You Choose the Right One?
Selecting a window grille involves considering material, design, and function. Common options include:
- Aluminium Window Grilles – Lightweight, rust-resistant, and affordable, making them ideal for HDB flats and condominiums.
- Wrought Iron Window Grilles – Strong and decorative, often used for landed properties and classical interior designs. They require rust protection.
- Stainless Steel Window Grilles – High strength and corrosion resistance, suitable for homes near coastal areas where moisture levels are high.
- Invisible Window Grilles – Made of high-tensile cables, perfect for modern apartments where maintaining an open view is a priority.
How to Choose the Right Window Grille?
- For HDB Flats – Aluminium grilles are the most common choice as they are affordable, lightweight, and comply with HDB guidelines. If you want an unobtrusive look, opt for invisible grilles, which provide security without blocking natural light or airflow.
- For Landed Properties – Wrought iron is a great option for decorative and intricate designs, but if you want something modern yet durable, stainless steel is a better long-term investment due to its higher strength and rust resistance.
- For Coastal or Humid Areas – Choose stainless steel grilles as they are highly resistant to corrosion. Wrought iron may rust faster in such environments, requiring regular maintenance or protective coatings to extend durability.
- For Families with Young Children – Opt for grilles with closely spaced bars or invisible grilles with child-safe lock systems to prevent accidents while maintaining an open, modern look. Consider custom height adjustments for added safety.
Beyond function, consider custom designs to match your home’s aesthetic. Many installers offer powder-coated aluminium grilles in different colours to blend seamlessly with interiors.
By balancing safety, design, and practicality, you can select a window grille that meets your household’s needs while complementing your home’s overall look.
