Welgemoed blinds questions: slope light, wind and estate rules

Because no eave can save it. At Cape Town's latitude the noon sun sits in the northern sky and stands near-vertical in late December, so an ordinary overhang shades north glass without help. From about three in the afternoon the summer sun comes in sideways, under any overhang and at eye level, straight through the biggest view glass in the house. With a UV index in the extreme band from October to March, that is glare, heat and fading arriving together. Only something at the glass itself stops it, which is why the guide starts with the west wall.

No. The north wall is well-mannered: steep and eave-shaded in summer, low and warming in winter. By June the noon sun has sagged to around 33 degrees and pours deep into a north room, which on a slope with wet, grey winters is free heating. A permanent blackout throws July's warmth away along with January's glare. This wall wants something adjustable, a sunscreen roller or a tiltable slat, so you can manage the light rather than block it.

Sunrise arrives hard and early into east rooms, then the wall goes quiet by mid-morning. Heat load is trivial; sleep is the whole brief, and it is an interior job all the way. A blockout roller settles it. If the bedroom also owns a view worth waking up to, a double roller carries sunscreen and blockout on one compact bracket, so the room is not permanently dark but the sunrise can be shut out when it matters.

Openness is the share of the weave that is actually hole. Three percent is the glare-killer for the truly punished western glass: the room goes calm and the view softens to a muted picture. Five percent is the everyday compromise most Welgemoed lounges land on, with noticeably more view and still enough control for glass that gets an hour or two of low sun. Ten percent keeps the panorama almost intact and suits windows that catch brightness rather than direct fire. The consultant holds the actual fabrics against your actual light at the measure.

Think moisture, not sun. The south wall gets barely any direct sun, the least airflow, and the most winter condensation on a slope that takes the north-west fronts head-on. Fabric cells and standing damp are a bad marriage, so a honeycomb blind is the wrong reflex there even though it is the warmest blind in the range. Aluminium venetians are the wet-room specialists: steam and condensation wipe straight off the powder-coated slats, and the tilt still gives light and privacy by degree. Keep timber out of genuine damp, where it swells and marks.

Only with the right spec. Height is why Welgemoed has its views and why it takes the summer south-easter harder than the streets below, and an awning caught open in a strong gust is a sail. On this slope the automatic wind sensor that retracts the awning before the gust does damage is a condition of fitting, not an extra. A full cassette that seals fabric and arms away suits an exposed, weather-facing terrace; semi-cassette or open mounting can work where the position is more sheltered. The fixing substrate is checked on site before anything is quoted.

They are partners, not substitutes. An awning is overhead shade for the lunch table, and the low side-on evening sun ducks straight under it. A zip screen is a vertical product: its fabric is locked into zipped channels down both sides, so it stands taut against gusts, low sun and mosquitoes while the outlook stays visible through the mesh, but high-noon sun comes straight over the top of it. Screens for the wind and the level sun, canvas for the overhead. The terraces up here that work hardest run both.

No, and we say so plainly. The roller shutters we fit are shading products, made for sun, heat, glare and light control on the outside of the glass. They are the heaviest shading in the range for the one window that bakes relentlessly every February afternoon, rolling down from a slim headbox and sitting quietly on the facade the rest of the time. They are not security-rated, which is a different product altogether. Remember also that down means dark: a closed roller shutter takes the view and daylight with the heat, so it is an on-demand tool rather than an all-day companion.

We confirm the rules first. Secure enclaves and the estates nearby often run architectural or body-corporate guidelines, and anything on the outside of the house, external venetians, roller shutters, awnings and zip screens, may need its colour and profile signed off. We check your estate's scheme before quoting any external product and supply the product specification sheets an aesthetics committee typically asks for alongside the quote. Unpicking an installed awning after a committee letter is nobody's idea of a good month, so nothing arrives on install day that has to come down again.

Completely. The Welgemoed that grew up around the golf club is oaks, settled double-storeys and houses with deep reveals, existing pelmets and window lines that have looked right for decades; shading one is restoration work as much as fitting, and the treatment has to slot into the architecture already there. The newer double-storeys climbing the slope have entire walls of view glass and a heat-load problem rather than window lines to respect, so the conversation goes straight to external shading, wide spans and motors. Reveal depth alone puts the two in different worlds.

At the window-schedule stage, not after the ceilings close. New estate homes increasingly wire for motorisation during the build itself, which avoids a retrofit and gives every blind app or schedule control from day one. Concealed rollers that drop from a slim bulkhead slot have to be planned, because the slot and the motor cabling must exist before the ceiling is sealed. A full house of new windows also suits one coordinated specification, so fabric, colour and control type match from main bedroom to scullery. We are happy to time the measure and fitting with whoever is running the build.

Either, and the house decides. Rechargeable battery motors slot into a finished home with no chasing of walls; wired motors belong in a build that is still open, where cabling can be routed before the ceilings close. Which one suits you depends on what power we can reach, and that is one of the things ten minutes on site settles that a phone call never can. Sensors ride on the same system: a sun sensor drops the west blinds before the four-o'clock heat, home or not, and a wind sensor stows the awning when the gusts pick up.

Most fabrics run happily to around three metres in a single drop. Past that the tube starts to deflect and the fabric can wander on the roll, so we split the opening into a linked pair, usually motorised so both halves move as one, with a slim join line placed where a mullion or frame already breaks the glass. On Welgemoed's wide sliders onto the garden or pool deck this is a regular conversation, and it is also where vertical or panel blinds come into their own.

Five things. The wind, corner by corner, because on an elevated stand the south-easter mauls one edge of a terrace and barely touches another, and that sets the screen, the awning and the sensor threshold. Reveal depth in millimetres, with the handles, stays and bars that eat into it. The wall under the wall, since face-brick, timber lintel, aluminium section and plasterboard each take their own fixing and a heavy motorised blind in this wind is a safety matter before a cosmetic one. Where the power hides. And what your estate will sign off.
