Zip screens — the deck closed in, the water view still open

The zip difference

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 answers

View-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 Knysna

The 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 notes

Motorisation 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.
