When you’ve just collected your keys, one of the first big decisions is how to keep your home safe—especially if you have young children, pets, or a high-floor unit. Traditional metal grilles may feel dated and bulky, which is why many new homeowners are now turning to invisible grilles for their windows and balconies.
Below, we’ve answered the questions most new homeowners ask, so you can decide if invisible grilles are right for your home.

Content
Are Invisible Grilles Safe?
Yes. The cables are made of high-tensile stainless steel coated with nylon, strong enough to withstand impact and pressure. You can also customise the spacing (typically 2–4 inches) so children and pets cannot squeeze through.
Are They Approved by HDB and Condos?
Yes, invisible grilles are compliant with the Housing Development Board (HDB) and accepted by most condo management corporation strata titles (MCSTs) since they don’t alter the façade. That said, it’s always best to check with your developer or management before installation.
How Do They Look from Afar?
From a distance, invisible grilles really do “disappear.” You’ll enjoy unobstructed views, natural light, and ventilation—something traditional aluminium or iron grilles simply can’t match.
How Much Do They Cost?
Pricing is usually by square foot. Windows can range from a few hundred dollars, while full-sized balconies may be over a thousand. The investment pays off in both safety and aesthetics, especially compared to resale value down the road.
Will They Last in Singapore’s Humid Weather?
Yes. The grilles are built with 304 or 316 marine-grade stainless steel, which resists rust and corrosion. With minimal upkeep—just a quick wipe-down—they’ll stay strong and clear for years.
Do They Come with Warranty?
Most professional installers provide a 5–10 year warranty against rust and cable breakage, giving you peace of mind.
Can I Customise the Design?
Absolutely. You can choose vertical, horizontal, or angled layouts, and even opt for sliding or casement styles depending on your window or balcony. The goal: safety without compromising on design.
Final Word: Safety With Style
Invisible grilles are one of those smart investments that balance practicality with modern living. For young homeowners, they offer the safety you need without sacrificing the open, airy feel of your new home.
