Why Invisible Grille is a "Must -Have" in Your Home?
- No Blocked Vision
- Anti-Rust
- Built Alarm System (Optional)
- Protect Children
- No More Cages
- Easy Escape During Emergency
- Fast Installation

Anyway, a picture speaks a thousand word. Take a look at how an invisible grille look like?


From what I observe, Invisible Grille looks like thin wires strung across the balcony...and thus helps blend into the interior, exterior design and improves the overall aesthetic of your home. Invisible grille offers you better visibility as compared to traditional installation and most importantly, it doesn't compromise safety and security concerns. Installers also offer integrated 24/7 alarm system for the Invisible Grille owners. This is a new solution to home owners who are looking for window and balcony protection. 

legate.com.sg also offers invisible grille installation. Take a look at this gallery which features their past projects.
