| Primary planning goal | Balance shade, airflow, outward view and partial privacy. | Retain outward visibility while creating a more continuous transparent barrier. | Prioritise shade, visual privacy and stronger visual screening. |
|---|
| Airflow | Open mesh constructions can retain more airflow, depending on openness and wind conditions. | Airflow is more restricted when the blind is deployed because the material is substantially continuous. | Airflow is more restricted while deployed; ventilation should be planned through other openings where required. |
|---|
| View / privacy | Openness percentage changes the balance between outward view and privacy. | Maintains a clearer visual connection through the material, subject to reflections, condensation and cleanliness. | Provides the strongest visual screening of the three broad pathways when deployed. |
|---|
| Sun / heat planning | Useful for solar control while retaining some view and ventilation; exact performance depends on the selected fabric. | Can reduce direct weather exposure but should not be treated as the primary solar-control choice without exact product data. | Can provide stronger shade and glare control where view-through is not the priority. |
|---|
| Rain / enclosure expectation | Treat as an outdoor screen, not a sealed rain barrier or storm shutter. | Can improve day-to-day rain separation in suitable configurations, but it is not a sealed building envelope or severe-storm system. | Can screen weather in normal outdoor use, but exact rain performance and operating limits remain product-specific. |
|---|
| Key project inputs | Opening size, openness, wind exposure, view/privacy target, controls and maintenance. | Opening size, guide system, temperature exposure, service access, controls and cleaning. | Opening size, privacy/shade target, wind exposure, controls, colour/heat considerations and maintenance. |
