Singapore’s most commonly installed invisible grille, nylon and teflon coated stainless steel cables offer a clean, nearly invisible barrier for your HDB or condo windows and balconies. If you’re a renter, new homeowner on a budget, or simply want a fuss-free short-term solution — this is the most practical choice in the market.
Endo Grilles has started installing homes of nylon coated invisible grilles across Singapore since 2017. Our cables are stainless steel at the core, coated with either nylon or teflon for added durability and a smooth, clean finish.
What is a Nylon or Teflon Coated Invisible Grille?
Nylon and teflon coated invisible grilles — sometimes known in the industry as Nano cables — are stainless steel wire ropes with a BASIC thin polymer coating applied to the surface. This coating makes the cable smoother, reduces friction, and provides a layer of protection against minor moisture exposure.
The stainless steel core gives the cable its strength, while the nylon or teflon coating gives it a cleaner appearance and slightly longer lifespan compared to bare stainless steel cables. These grilles are installed vertically or horizontally across your window, balcony, or staircase opening — creating a child-safe barrier that is virtually invisible from a distance.
Why Choose Nylon & Teflon Coated Invisible Grilles?
Unobstructed Views
Unlike traditional metal grilles that block your view and make your home feel like a cage, nylon coated invisible grilles are so thin they disappear from sight. You get full natural light and an open, airy feel — even in a high-rise HDB.
Child & Pet Safety
Each cable is tensioned to withstand significant force, creating a safe barrier that prevents children and pets from falling through windows and balconies. Fully compliant with HDB window safety requirements.

Frequently Asked Questions
What is the difference between nylon and teflon coated invisible grilles?
Both are very similar — nylon and teflon are polymer coatings applied over stainless steel cables. Teflon (also called Nano coating) is slightly smoother with marginally better moisture resistance. In practice, both perform similarly for indoor Singapore conditions.
How long do nylon coated invisible grilles last in Singapore?
Typically 3–5 years for indoor use with no direct sun or rain exposure. For outdoor or balcony areas with weather exposure, we recommend upgrading to All Weather Cables which last 10+ years.
Can nylon coated grilles be installed on HDB balconies?
Yes, but only for sheltered balconies with minimal sun and rain exposure. For exposed outdoor balconies, All Weather Cables are strongly recommended for longer durability.
How much does nylon coated invisible grille cost in Singapore?
Prices start from $4.90 psf or $120 per area. A typical HDB living room costs $180–$300 depending on size. Get an exact quote using our instant quotation tool.
What happens if a cable breaks or loosens?
All Endo installations come with a 3–5 year warranty. If any cable breaks or loosens within the warranty period, we will rectify it at no charge.
Will invisible grilles affect my HDB resale value?
Invisible grilles are generally viewed positively by buyers as a child safety feature. They do not negatively affect resale value.
Can I remove the grilles when I move out?
Yes, invisible grilles can be removed. However removal will leave small anchor holes in your window frame. Most HDB buyers and landlords are not concerned by this.
How do I maintain nylon coated invisible grilles?
Simply wipe down the cables with a dry or slightly damp cloth every few months. Avoid abrasive cleaners. Check cable tension annually — if any cables feel loose, contact us for a free inspection.
