Semi-frameless is the lowest-cost option, for low-level edges with a drop under 600mm. Where the drop is 600mm or more, post & handrail is the value choice, as its posts and rail carry the load and it uses 10mm toughened glass. Spigot and channel systems put the load through the glass itself and use thicker laminated panes at height, which is what moves them up the price scale.
Both give you glass-led looks without posts. The spigot system holds each pane on two floor-mounted spigots — a frameless appearance with small fixings visible at the base. The channel system sets the glass into a continuous base channel with nothing else on show at all. Channel is the more premium route; spigot gets you most of the look for less.
It depends on the drop. For a low deck under 600mm, semi-frameless is the value choice. For a raised deck, spigot suits contemporary designs with minimal hardware, the frameless channel system is the premium pick where the deck is all about the view, and post & handrail suits decks with steps. Every system must be fixed into the deck's structural frame, not just the boards.
Post & handrail. It follows the pitch of the stairs and gives you a continuous rail to hold. Our other systems can serve the level areas either side, with post & handrail on the flight itself.
Not always. Our spigot and frameless channel systems use toughened laminated glass for drops of 600mm or more, with a top rail as an option rather than a requirement. Post & handrail always has a rail, and it is the system we recommend for stairs. Each system's page covers its own glass in detail.
Yes. Post & handrail follows the stair pitch and gives you a rail to hold, which is what we recommend on stairs. Our frameless and spigot systems can be used on the level landings either side.
