Zip screens — the deck closed in, the water view still open
Vertical outdoor screens running in zipped aluminium side channels — the product that turns a Knysna deck or marina terrace into a usable room on a windy afternoon, without walling off the view that put it there.
Why an ordinary drop screen flaps and this one doesn't
The fabric edge is welded into a zipper that runs captive in aluminium channels down both sides — no flapping, no gap for wind to get behind. An ordinary drop-roller screen escapes its guides in real wind; a zipped screen holds tension properly, which is the whole argument on an exposed Knysna deck, whether that's an open marina terrace on Thesen Islands or a dune-side patio at Brenton-on-Sea.
Mesh or clear — two fabric answersView-through mesh, or a genuine winter enclosure
Sunscreen mesh keeps the view out to the water while cutting glare, UV and insects, with daytime privacy from outside. Clear PVC panels go further — a wind-and-rain-proof enclosure that keeps the view completely open, the right call for a braai room or outdoor lounge you want to use through a wet Knysna winter month rather than just the dry stretches. Blockout options exist too, mainly for an outdoor cinema setup or killing a punishing west-facing sun on the deck.
Where zip screens earn their keep in KnysnaThe outdoor room, made to work
Marina-front decks on Thesen Islands, wide entertaining patios around the lagoon shoreline, and exposed positions along the Brenton-on-Sea dune strip are the three cases we fit these into most. Each wants a slightly different spec: sheltered lagoon decks can often run a lighter setup, while anything facing the open coast wants the full wind-rated cassette and motorised retraction described below.
Practical notesMotorisation and sizing
Motorisation is close to standard on wide spans — reaching across a 4m+ opening by hand every time the wind picks up gets old fast — and a wind sensor that retracts the screen automatically before a gust arrives is the responsible spec for any exposed position, the same logic as an awning. Channels colour-match to the structure, and multi-screen patio enclosures (wrapping two or three sides of a deck) are one of the biggest single jobs in the whole range.
Zip screen pricing, as a guide
Zip screens are guided by the square metre of screen, installed: R2,800 to R4,500 hand-operated, R4,000 to R6,000 motorised with wind-sensing control. Those tensioned channels and the sealed head are what put a screen above an ordinary outdoor blind of the same area — the reason the fabric holds its shape when the wind comes up the lagoon rather than flogging itself loose.
A deck is normally several bays rather than one wide screen, and a narrow bay is billed at a minimum rather than strictly by area. Fabric moves the figure too: an open mesh that keeps the view and a solid panel that keeps the weather out are not the same money. Each bay is measured free of charge and then priced on its own line in writing.
