Why Window Grilles Are Important in Singapore Homes
Window grilles are a necessity in many Singapore homes due to high-rise living and urban density.
1. Safety for Children & Pets
Open windows pose a serious fall risk. Window grilles help prevent accidents, especially in homes with young children, elderly parents, or pets.
2. Enhanced Security
Ground-floor and low-floor units are more vulnerable to break-ins. Window grilles act as a physical deterrent, improving home security.
3. Peace of Mind
Window grilles allow homeowners to keep windows open for ventilation while enjoying daily peace of mind.
Types of Window Grilles in Singapore
Choosing the right window grille depends on your budget, security needs, and design preference.
1. Aluminium Window Grille (Most Popular Window Grille in Singapore)
✔ Most commonly installed window grille
✔ Reliable, and rust-resistant
✔ Most affordable window grille in Singapore
Aluminium window grilles are the most popular choice in Singapore because they are cheap, low-maintenance, and durable. They come in various designs and colours, making them suitable for both modern and classic homes.
2. Wrought Iron & Mild Steel Grille (Best Window Grille for Security)
✔ Strong and sturdy
✔ Ideal for ground-floor or corridor-facing units
✔ Traditional and decorative designs available
These iron window grilles provide higher security but may require anti-rust treatment and maintenance over time.
3. Invisible Window Grille (Best for View & Aesthetics)
✔ Almost invisible from a distance
✔ Maintains an unobstructed view
✔ Popular for condos and high-floor units
Invisible window grilles use stainless steel cables under tension. They are ideal if:
You want safety without visual obstruction
Your unit has a good view
You prefer a minimalist look
Invisible window grilles are generally more expensive and require proper installation to ensure long-term safety.
What to Look Out for When Buying Window Grilles
Before choosing a window grill contractor in Singapore, always check these critical points.
1. Material Quality
Ask about:
Aluminium thickness or stainless steel grade
Rust resistance
Finishing quality (painted, sprayed, or powder-coated)
Cheap materials may look fine initially but fail over time.
2. Child-Safe Spacing & Cat-Safe Spacing
Grille spacing is one of the most important safety considerations.
Child safety:Recommended spacing is less than 5 inches to prevent children from squeezing through or getting stuck.
Cat safety:Cats are far more flexible. Recommended spacing is less than 2 inches to prevent pets from escaping or falling.
Always inform your contractor if your household includes children or cats, as spacing requirements differ.
3. Warranty & After-Sales Support
A reliable window grill contractor should provide:
Clear warranty coverage
Support for adjustments or repairs
