## Three Products, One Decision Path

“Balcony glass” covers three different builds: railings (the safety barrier at the edge), glass balconies (structural glass replacing solid balustrade walls), and glass curtains (folding panels that enclose the whole opening). Choosing well means walking one decision path — safety first, then weather, then look and budget — across whichever product your balcony needs. All three sit inside

 scope.

## Step One: Safety Sets the Floor

The barrier function is non-negotiable, and it fixes your glass options before taste enters the conversation. Balustrade glass must be safety glass — tempered or laminated-tempered to MS 1498 — at a thickness sized to the span between fixings and the panel height. Fall-critical edges favour laminated-tempered, which stays in place even if broken.

Only after the safety spec is settled do the style questions open up: frameless or framed (our

 guide covers that trade), clear or tinted, standoffs or base channel.

## Step Two: Weather Decides the Extras

Malaysian balconies live with driving rain, afternoon heat and, on high floors, real wind load. Exposure shapes the specification:

-   **Wind** raises glass thickness and fixing demands on high, open elevations
-   **Rain** makes drainage planning essential for glass curtains — water must escape the track, not pond in it
-   **Heat** makes tinted or solar-control glass worth considering on west-facing edges

Glass curtains earn their keep here. Folded open, the balcony breathes; closed, it becomes usable in a downpour and cuts wind, dust and traffic noise.

> Many managements regulate balcony alterations — frame colours, tint levels, whether enclosure is allowed at all. We regularly prepare the simple drawings and specs management offices ask for; getting approval before fabrication saves everyone grief.

## Step Three: Budget, Honestly

| Option | Budget position |
| --- | --- |
| Framed railing | Most economical |
| Frameless railing | Mid to premium |
| Laminated-tempered barrier | Premium safety spec |
| Glass curtain enclosure | Priced per opening width and panel count |

Every project is custom-fabricated, so pricing follows your measured opening rather than a catalogue. The RM50 on-site measurement — deducted from your order — captures spans, heights, fixing substrate and drainage, and the quotation that follows covers glass, hardware and installation as one number.

Send us balcony photos and a rough width to start; we will tell you which of the three builds fits, and what it will cost.

## Frequently Asked Questions

What is a glass curtain?

A frameless folding-glass system that encloses an open balcony. The panels slide along a track and fold to one side, so the balcony can be fully open, fully enclosed, or anywhere between.

How thick should balcony glass be?

It depends on span, panel height and exposure — 12mm is a common balustrade baseline, with laminated-tempered constructions for fall-critical positions. We size each run individually.

Can you make custom sizes?

Yes. Every panel, fixing layout and curtain track is fabricated to your measured opening, including angled and stepped balcony edges.
