The screen that holds its line against wind straight off the bay

Why the zip channel matters here specifically

An ordinary drop screen flaps and escapes its guides in real wind — and this town gets real wind, even with the mountains behind it taking some of the sting out of the summer south-easter. A zip screen's fabric edge is welded into a zipper that runs captive in aluminium side channels, so it holds tension instead of billowing loose. That's the difference between a screen that lasts and one that's shredded by its second winter. Push west along the coast to the open beachfront at Strand and there is no mountain behind the balconies at all, so the wind rating leads the whole specification there — down to how wide we are prepared to run a single bay.

Sunscreen mesh, or clear for a winter braai room

Sunscreen mesh in a range of openness percentages keeps the harbour view while cutting glare and UV and giving daytime privacy from the street below. Clear PVC or crystal panels turn the same opening into a wind-and-rain-proof enclosure that still shows the view — the option most people choose when they want the deck usable through a Cape winter, not just in summer.

Fitted for the position, not just the opening

Motorisation is close to standard on wide spans, with a wind sensor recommended for anything genuinely exposed — the same logic as an awning. Channels are colour-matched to the structure rather than left as raw aluminium. On a managed estate that colour, and the way the channels are fixed, is usually the estate's business as well: at Harbour Island we ask about the rules on canal-facing fittings before anything is ordered. Multi-screen enclosures on a wraparound deck are quoted and fitted as one coordinated job rather than screen by screen.

What a zip screen costs here

Zip screens are guided by the square metre of screen, installed: R2,800 to R4,500 hand-operated, and R4,000 to R6,000 motorised with wind-sensing control. The zipped side channels and the sealed head are what push a screen above an ordinary outdoor blind of the same area — that hardware is the whole reason the fabric stays taut in a blow instead of flapping itself apart.

A stoep is normally several bays rather than one wide screen, and a narrow bay is billed at a minimum rather than strictly by area. Fabric shifts the figure as well: an open mesh that keeps the view and a solid PVC panel that keeps the weather out are not the same money. Every bay is measured at no cost and priced on its own line in writing.
