Balcony Invisible Grills
Tensioned steel cable across the balcony opening — full fall protection, almost no visual obstruction.
A conventional welded grill turns a balcony into a cage. Invisible grills do the same safety job with 2.5mm stainless steel cable set at close vertical spacing, running between an aluminium track fixed at the floor and the soffit above.
The cable is thin enough to disappear against a bright sky at normal viewing distance, so the balcony still feels open and the room behind it keeps its light. The system carries a lateral load well beyond an adult leaning against it, and the spacing is set so a child cannot pass through or use it as a ladder.
We measure on site, fabricate to your opening, and fit in a single visit for most balconies.

Balcony Invisible Grills — common questions
Will the cable sag over time?
Each run is tensioned at installation and the track allows re-tensioning. We check tension free of charge at the first annual service.
Can I still dry clothes on the balcony?
Yes. The grill runs at the opening; the floor area behind it is unchanged. Many customers pair it with a ceiling cloth hanger.
What material are the nets made from?
Knotted high-density polyethylene, UV stabilised. HDPE is chemically inert, waterproof and does not degrade in sunlight the way untreated polypropylene does. Nets are tensioned on a stainless steel wire frame using screw pins, turnbuckles and hogging staples, so the installation stays tight rather than sagging after the first season.
How much does it cost?
Pricing starts from a base rate per square foot and varies by product — invisible grills cost several times more than netting. Use the estimate calculator for an approximate figure, then book a free site visit for an exact written quotation. Measurements taken over the phone are almost always wrong.
How long will the installation last?
Five years is typical for HDPE netting in direct sun, longer on sheltered elevations. Invisible grills last considerably longer — the stainless cable is the limiting component and it does not corrode. Sun exposure is what ages netting, not rain.
Can a bird cut through the net with its beak?
No. HDPE at the gauge we use cannot be cut by a pigeon or crow. The failure mode for bird netting is never the mesh — it is a gap left at the perimeter, which is why edge sealing is the part of the job that actually matters.
