Stellenbosch Wine Route blinds: questions from four wards

Because the wine-of-origin wards were never drawn for tidiness. Elevation, rainfall and shelter change enough from one ward to the next to change what grows there, and published figures make the point: from roughly 100 m above sea level to 1,200 m, and from about 400 mm of rain a year to as much as 2,000 mm. A tasting-room wall of glass in an open, low-lying ward faces a fundamentally different afternoon to the identical wall fifteen kilometres away on a mountain slope, which is why shading either from a catalogue is guesswork and why we measure each ward for its own numbers.

Something held in tension rather than hanging free. Bottelary is the lowest, driest ward on the drive, with nothing standing between a building and the sky, so a west-facing cellar wall holds sun until it sets and wind arrives across open ground without warning. A zip screen, mesh tensioned inside aluminium side channels, will not lift, flap or wear at its edges the way an unrestrained fabric does, and it turns an open stoep into a room you can seat people in on a February evening. Where the shading has to go on the glass itself, this is external-shading country, with sunscreen mesh inside to hold the view.

It inverts the priority. Devon Valley is a compact bowl held between ridgelines, and where the air does not move, heat accumulates in the walls and paving through the day and lets go slowly in the evening, so a homestead there can be several degrees warmer at seven than one on the open ground you have just left. The whole argument becomes intercepting heat before it builds, which still puts external shading first, and a folding-arm awning suits this basin better than anywhere else on the route, run right out over a tasting table without the wind rating dominating the choice. Shelter is relative, though, so the wind sensor stays standard.

Because the daily shape of the light there is a hard, bright morning and a shadow line that arrives sooner than the almanac says, as the mass of rock behind cuts the afternoon short. Where the whole problem is a strong morning and a short afternoon, a fixed fabric position is the wrong tool; you want something steered through the day. Slats tilted up bounce light onto the ceiling, tilted down send it to the floor, and level put the mountain back in the window. On old homestead windows 50 mm timber slats sit at the rhythm of the original glazing; on a newer cellar-door face, aluminium external slats do the same job outside the pane.

It decides the material before the sun does. The pass ward is the highest and wettest of the four, with rainfall published as high as roughly 2,000 mm a year, and sustained damp is hard on the wrong materials. Timber slats belong indoors here in a room that dries out; a bathroom, a cellar workspace or a room that runs cold wants aluminium. Cellular honeycomb blinds do real work in guest accommodation, where the complaint is more likely a cold, slow-to-warm room than a bright one. And because the pass accelerates the air moving through it, anything mounted outside is specified against gusting and motorised with a sensor. A wet ward finds out cheap exterior hardware fastest.

No, and it is a real site question rather than boilerplate. Where the oldest roofs along the route are still thatched, South Africa's thatch regulations set clearance requirements around conductive material near and under the thatch, which governs where a fixing for an awning, a screen track or an external slat system may land. That is one of several reasons we would rather look at a roof than a photograph of one. On the same buildings the sixty-year heritage protection applies to anything on the outside face, so the old core generally takes an internal blind inside the reveal and the newer wing takes the external work.

While the bulkhead is still a drawing, not after the plasterer has packed up. A concealed blind vanishes into the ceiling of the new wing until the sun swings round, and that only works if the slot is planned with the ceiling. The new cellar-door or cottage wing is the building with the large glass and the actual heat problem, and it carries none of the heritage constraint of the lime-washed core, so it is also where external shading on the outside of the glass earns its keep. Bringing us in at drawing stage lets the two be planned together.

Because this is a winter-rainfall basin. The district is wettest in June and July and driest in January and February, so outdoor shading here is tested by sustained wet-season wind and rain, not by a highveld hail calendar. What we design against in summer is the south-easter, which builds from around September into March and typically peaks around five in the afternoon, exactly when a terrace awning is most likely to be out, and whose influence falls away as you move inland. Every motorised awning or screen on an exposed terrace carries a wind sensor as standard, and a full cassette keeps the fabric dry on exposed positions.

No. All day it gives daytime privacy, because the bright side is outside and the mesh reads as a surface from there. The moment the lamps are on inside, it reverses and the lit room becomes the thing being looked at. On a working farm with nobody for a kilometre that may not matter at all; beside a public tasting terrace it matters. Where a space needs both, a double roller carries mesh and blockout on one bracket, and a banded day-and-night fabric does a lighter version of the same trick on a single tube.

Usually one bracket carrying two fabrics. Guest cottages built for overnight visitors often end up on a double roller, blockout for night and sunscreen for the rest of the day on the same headrail, which is the practical middle ground between daylight over the vines and an actual dark room for a guest who has driven a long way. A banded day-and-night blind tunes the same room hour by hour on a single tube, though its solid bands are not true blockout. In a stone-walled west-facing bedroom a cellular blind gives genuine blackout with an insulating bonus.

Yes, and the width decides the product. Past roughly three metres of unbroken fabric a roller needs either a central join line or a second, linked blind, usually motorised so the sections travel together with the joins set against the door mullions. Vertical and panel blinds cover a wide stacking door without a seam down the middle, tracking back into a slim stack against the jamb so the opening you spent the money on is still an opening once the blind is drawn. Timber venetians past about two metres get split or motorised rather than left as a heavy hand tilt.

It takes the person out of the loop. Timers, sun sensors and wind sensors mean the shading happens on schedule whether or not anyone is on the farm that week, which at harvest is a real consideration rather than a hypothetical one: the awning retracts itself before the south-easter peaks, the west blinds drop before the afternoon, and the cellar doorway nobody wants to reach with a pole moves with the rest. Inside the glass, chain control with a wall-anchored tensioner remains standard and perfectly good on an ordinary homestead window; motorisation earns its place on wide cellar-door glass and runs of linked panels.

They can. Clear PVC or crystal panels in the same zipped side channels give a wind-and-rain-proof enclosure that keeps the view entirely, the right call for a winter tasting room that still wants to feel outdoors, with sunscreen mesh or blockout available bay by bay for the openings that need glare control instead. Two honest riders: clear panels need periodic cleaning to stay genuinely clear, and a multi-screen enclosure around a whole terrace is a bigger-ticket, bigger-planning job than a single blind, so it belongs in the conversation at the measure rather than as an afterthought.

Because ward figures describe a district, not a wall, and five things on the ground decide the quote. Which era each opening belongs to, old core or newer wing, which settles internal versus external before anything else. Reveal depth, measured at several points, since homestead openings are rarely square. What the wall and the roof are made of, because substrate decides the fixing and thatch decides where a fixing may not go. Exposure at that exact spot, since a courtyard and a ridge-top terrace on the same farm behave nothing alike. And power and approvals. Finding those out first is cheaper for everyone.
