What is an invisible grille?

All the safety, none of the cage

An invisible grille replaces bulky traditional grilles with a series of fine, high-tension stainless-steel cables spaced close together. From a few steps back they all but disappear — so you keep natural light, airflow and an unobstructed view, while gaining a strong barrier against falls and intruders.

Unobstructed view — barely visible cables keep your scenery intact.
Child & pet safe — closely-spaced cables prevent falls.
HDB & condo friendly — neat, low-profile and easy to maintain.

Choose your fit

Six invisible grille types

Different windows call for different grilles. We supply and install all six, and advise you honestly on the best fit for every opening in your home.

Most secure

Fixed Invisible Grille

A permanent grille made of several SS316 stainless-steel cables, anchored to solid concrete for maximum stability and security.

Permanent

Fixed Frame Invisible Grille

Installed on top of the window frame. It can't be opened, but you can still reach and operate your windows behind it.

Easy cleaning

Casement Invisible Grille

Opens inward for improved access to your windows for cleaning, and easy reach to air-conditioning units outside.

Seamless

Sliding Invisible Grille

Installed above the window frame for a seamless, transparent finish — easy access while keeping everyone safe.

Widest opening

Bi-fold Invisible Grille

Folds fully to the left or right for the best airflow, the widest view and full, unobstructed access to the outside.

For balconies

Structure Invisible Grille

Designed for balconies with a false ceiling — fully encloses the space to create a secure environment for the family.

Invisible grille FAQs

Are invisible grilles safe for children and pets?

Yes. The cables are spaced closely together and held under high tension, forming a strong barrier that prevents children and pets from falling from windows, balconies and open spaces — while keeping the view clear.

Will an invisible grille block my view?

No. The cables are very fine and, from a normal viewing distance, they're barely noticeable. You keep your natural light, airflow and scenery — that's the whole point of an invisible grille.

What material do you use?

Marine-grade 316 stainless steel (SS316), known for its strength and resistance to rust and corrosion. It's coated to withstand humid weather and is designed for minimal maintenance.

Which grille type suits my home?

It depends on the window and how you use it. Fixed and fixed-frame grilles are the most secure; casement opens inward for cleaning and air-con access; sliding and bi-fold offer the easiest access; structure grilles enclose balconies. We'll advise on the best fit during a free site visit.
