Vergenoegd Löw — EIFS facade on the wine estate

Vergenoegd Löw is a wine estate outside Cape Town. The buildings in this album are single-storey, flat-roofed and low, set in open ground between the vines with the mountains behind them. There is nothing to hide behind: full sun on every elevation, wind off the flats, and a client who sells the view. The facade had to be the finish, not a base for one.

Technopol supplied the Terraco EIFS: EPS insulation board, mechanically fixed, then a Styrobond DP basecaot with Terramesh glass-fibre mesh embedded in it, then the Terracoat textured topcoat as the weatherproof outer skin. That is the whole external wall build-up — insulation and weatherskin in one system, on the outside of the structure.

What the site photographs prove is the continuity. In the December record the EPS is carried across the face of a sheathed frame and turned up and over the roof edge in the same plane, with the washer-plate fixings visible in a regular pattern. The reveals are cut and returned in the EPS itself. There is no point on the elevation where the insulation stops and the structure comes through — no expressed slab edge, no interrupted line. That is the reason to specify continuous external insulation rather than a cavity, and it is a thing a photograph can actually show.

By the January record the same walls are rendered and the building reads as one monolithic white block. The junctions are where a specifier should look: the render returns into each reveal and stops clean against the aluminium frame, and the parapet is capped in the same skin. The surface is the Terraco grain — a coating with the texture built into it, not paint over plaster — and it is the coating, not a separate render, that is carrying the water. The audited spec puts the pull-off bond above 2.0 N/mm² and the coating at Sd <0.10 m: it sheds liquid water and still lets the wall breathe.

One thing worth saying plainly: the SANS/BS 8414-2 facade fire-spread PASS applies to the full EIFS system built exactly as it was tested, and it is a reaction-to-fire result, not a fire-resistance rating. The inner wall still has to earn its own FRR.
