What Are Parts of a Balcony Called?

Homeowners and builders often ask about the correct names for balcony components. Here’s a quick guide to the essential parts—useful for design, safety checks, and SEO-friendly product listings. The balcony deck (slab) is the walking surface, tied to the structure with a ledger and supported by joists or a concrete cantilever. Moisture protection comes from the waterproofing membrane, drip edge, and flashing at wall junctions. The fall-protection system is the guardrail/balustrade, which includes posts (newels), top rail/handrail, bottom rail (shoe/base channel), and infill—typically balusters/spindles, glass panels, perforated metal, or cable. Side or underside finishes may feature fascia cladding and soffit panels. For glass systems, note the base shoe, post brackets, and end caps; for metal systems, specify mounting type: top-mount, fascia/side-mount, or core-drilled.

When planning, confirm baluster spacing, rail height, and live-load rating per local codes (e.g., IBC/EN standards). Popular searches include “balcony railing parts,” “balustrade components,” “glass balcony systems,” and “waterproof balcony flashing.” Clear terminology improves quotes, reduces site errors, and helps users find the right products online.
