This guide will walk you through everything you need to know about window grilles in Singapore.
What Are Window Grilles?
Window grilles are protective frameworks installed over windows to enhance security and style. They come in materials like aluminium, which is strong and resists rust. They also have powder-coated finishes. These finishes add elegance and resist scratches and fading. Grilles not only act as a barrier against break-ins but also ensure the safety of children and pets, making them essential to any Singapore home.
Are window grilles compulsory for HDB flats?
No, window grilles are not compulsory in HDB flats or condos in Singapore. However, it is highly recommended to prevent accidents while providing added security against unauthorized access. Although not mandatory, experts strongly recommend using grilles for safety, especially in homes with children or pets.
Types of Window Grille Designs: Finding the Perfect Fit
The ideal window grille design depends on your home’s style, security needs, and personal preferences. Here are some popular options to consider:
1. Latticed Window Grilles

Characterized by a crisscross pattern, latticed grilles provide a classic, elegant look while ensuring strong protection. They work well for both traditional and contemporary homes.
2. Horizontal Bar Grilles

Horizontal bar grilles are sleek, simple, and one of our most popular options. Ideal for modern interiors, their clean, straight lines offer a minimalist yet stylish appearance while ensuring dependable security. The standard gap between each bar is 100mm, providing a balance between safety and views. A major advantage of this design is its easy maintenance and cleaning, making it perfect for busy homeowners. Combining functionality, convenience, and aesthetic appeal, this grille is a top choice among our customers.
3. Slim Grilles (Only available in Horizontal Designs)

Slim grilles are a modern and stylish option, offering the same level of safety as traditional grilles but with a sleek, less obtrusive profile. Perfect for homes aiming for a minimalist aesthetic, these grilles are a great way to blend functionality with a contemporary look.
4. Invisible Grilles

Invisible grilles feature slim, high-tensile cables in place of traditional bars, offering enhanced safety without obstructing your view. They are ideal for homeowners seeking a clean and open aesthetic, making them especially suitable for properties with scenic surroundings. These fixed grilles pair perfectly with swing and slide windows, ensuring unobstructed views while maintaining maximum safety.
