The Custom Blinds case study reports

One per product category. Each opens with a short set of key protocols, then the field evidence behind them.

Awnings: wind loading, fixing failures and the automation standard
What fails when wind loads are underestimated, why Somfy wind-sensor automation is the standard recommendation for retractable awnings on the Garden Route, and how wall substrate assessment decides whether an installation proceeds at all.
Outdoor blinds: uplift protection and coastal specification
Why standard ground latches fail as the wind builds, how core drilling and chemical anchors address uplift, and what the coastal maintenance protocol actually requires.
Shutters: coastal climate, heat and security
How PVC and aluminium shutters cope with salt, heat and daily use, why timber struggles at the coast, and where aluminium security shutters belong.
Indoor blinds: heat gain, glare control and coastal hardware
Honeycomb insulation performance, sheer fabric selection for large-windowed coastal homes, and why the hidden hardware fails before the visible slats.
