Invisible Grilles in Singapore: Prices, Affordability, and Practicality for Balconies and Windows

Invisible grilles are becoming increasingly popular in Singapore, especially among HDB and condo dwellers who seek safety without compromising aesthetics. Whether you're a parent concerned about child safety, a pet owner, or simply want peace of mind, invisible grilles offer a modern solution for securing balconies and windows. But how much do they cost, and are they truly worth it?

What Are Invisible Grilles?

Invisible grilles are made from high-tensile stainless steel cables, often coated with nylon or other protective materials. They are spaced evenly apart (typically 2–4 inches) and installed either vertically or horizontally. When viewed from a distance, they are barely noticeable—hence the term “invisible.”

Average Prices of Invisible Grilles in Singapore

The cost of installing invisible grilles in Singapore depends on several factors:

• Size of the area (sq ft)
• Grille type (fixed, casement, or sliding)
• Material quality (standard vs. premium stainless steel)
• Installation complexity (curved balconies or high-rise units)

Estimated Pricing (2025):

| Type | Price Range (SGD) |

| ------------------------------------ | ----------------------- |

| Living room windows | \$12–\$18 per sq ft |

| Bedroom windows | \$12–\$18 per sq ft |

| Balcony (standard size) | \$900–\$1,800 total |

| Custom structures or curved surfaces | Custom quoted |

Some vendors offer discounts for larger surface areas or full-home installations. Maintenance packages may be included in premium pricing tiers.

Why It’s Practical to Install Invisible Grilles

Safety without Sacrificing View

• Perfect for high-rise units: keeps children and pets safe without obstructing views or ventilation.

• Complies with Condo Aesthetics

• Most MCSTs (Management Corporation Strata Title) in private condos prefer invisible grilles due to their unobtrusive appearance.

Low Maintenance & Durable

• Made from rust-resistant materials that last years. Most cables are coated to withstand Singapore’s humid climate.

Customisable Options

• Choose cable spacing, colour (black, silver, white), and type (fixed vs. operable) to suit your unit’s layout.

Child and Pet Safety: A Key Benefit for Families

For families with young children or energetic pets, invisible grilles provide an essential layer of security. In high-rise apartments, accidental falls are a real concern—especially when children lean against open windows or balconies. With invisible grilles installed, parents can rest easier knowing there’s a physical barrier that doesn’t obstruct airflow or natural light.

Cats, known for their climbing habits, are particularly at risk of slipping through traditional grilles or open gaps. Invisible grilles with narrower spacing (2 inches apart) can be tailored to prevent this, ensuring your pet stays safely indoors without the need for unsightly mesh or cages.

How It Can Be Affordable

• Modular Installation: You can choose to install grilles in stages—start with the balcony and add window grilles later as your budget allows.

• Vendor Promotions: Many companies offer package deals or seasonal promotions (e.g., up to 20% off during National Day or year-end sales).

• Long-Term Investment: Compared to traditional grille replacements or repairs, invisible grilles can be a better value in the long run.

Choosing the Right Vendor

When sourcing an installer:

• Ensure they use marine-grade 316 stainless steel for superior durability.
• Ask for BCA compliance and warranty (typically 5–10 years).
• Check reviews on platforms like Qanvast, Hometrust, or Google.

Popular vendors in Singapore include:

• CSA Invisible Grille
• LeGate
• Invisys
• SkyGrilles

Final Thoughts

Installing invisible grilles is a smart move for any homeowner looking to balance safety, aesthetics, and property value. With prices ranging from $12 to $18 per square foot and multiple installation options, it’s both affordable and practical—especially for balcony and window spaces in Singapore's high-rise environment.

Beyond the sleek appearance, invisible grilles offer peace of mind—whether you're safeguarding a curious toddler, a playful cat, or simply want to secure your unit without bulky bars. With low maintenance, condo-compliant designs, and long-lasting materials, they’re an investment in both safety and lifestyle.

If you’re upgrading your home or renovating a new BTO or resale flat, consider invisible grilles not just as a trend, but as a reliable and future-proof addition to your home security setup.
