External venetians for a Kommetjie facade
The most effective heat control there is, because the sun never reaches the glass in the first place — motorised as standard, with a wind sensor built in for the days the south-easter means business.
Wide aluminium slats, mounted outside the glass
An external venetian is a venetian blind that lives outside the window rather than inside it — wide aluminium slats, typically 60–90mm, running in guided side rails or cables, tilting and raising much like an interior venetian but doing the work before the heat ever crosses the glass. On a north- or west-facing wall the difference this makes to the room behind it is not subtle: an interior blind manages heat that has already arrived, while an external one intercepts most of it at the pane.
Because it lives outside, it is effectively always motorised, and always paired with a wind sensor that retracts the blind automatically before a gust arrives — a blind left extended in a serious wind doesn’t survive it, exterior products here or anywhere else. Finishes are powder-coated for weather exposure, and slats tilt through a full range so you can steer light without losing the room entirely.
Why it suits a Kommetjie home specifically
Kommetjie’s architect-built beach houses tend toward large glazed walls chasing the dune and ocean view, and because the village sits low and flat rather than tucked under a cliff, that glass rarely gets any natural shade from the terrain around it. Most of it looks south-west across the dunes rather than dead into a sunset, which means steady afternoon heat and glare off open water rather than one blinding hour — exactly the load an external venetian is built to intercept. Fitting one is also, honestly, a facade decision: on an architect-built house near the reserve boundary we’ll flag anything worth checking with you before it’s ordered, and the powder-coated finish needs to handle salt air reaching every elevation, not only the one facing the water.
External venetians, answered
Will it actually survive Kommetjie’s wind?
That’s the point of the wind sensor — it retracts the blind automatically before a gust arrives, so you don’t need to be home or watching the sky. We confirm the specific wind rating for your elevation at the free measure, since exposure varies more from street to street here than it does in most suburbs.
Is this the same as a roller shutter?
No — different product. An external venetian tilts and raises like a blind, giving you shade with a view through the open slats. A roller shutter is a solid slatted curtain that rolls down for full blackout and shading, with no in-between tilt position. Both live outside the glass; which one suits depends on whether you want to keep some visibility while shading.
Does an exterior alteration like this need any sign-off near the dune boundary?
Sometimes, depending on exactly where the property sits relative to Table Mountain National Park and the protected dune belt beside it. We check your position against that boundary at the free measure and flag anything worth confirming before we quote — better to know upfront than after ordering.
