01 / Span1
Clear span between beams
The span sets the fabric width and the number of seams. Give the clear distance, not the pergola footprint, and say which way the fabric runs.
Up to 3200 mm per drop
Application
Sunscreen fabric for pergola and patio shading
A horizontal or sloped span between beams. The fabric sags between supports, sheds nothing, and takes a different load path from a vertical blind.
Horizontal spans behave differently
Nothing hangs; everything spans.
On a pergola the fabric runs between two beams and is tensioned at both ends. There is no bottom bar to pull it straight, so the span sags under its own weight and the amount of sag is set by the tensioning detail. The open weave lets air through, which reduces the wind load on the fabric, and lets rain through, which means the pergola is shade and not shelter.
Span
Tell us the clear span between beams and how the fabric is tensioned at each end.
Water
An open weave is not waterproof. Rain passes through the openings.
Weight

A pocket for a tensioning bar, a welded loop, or a track are different operations. Tell us which one the structure uses.
Welded, sewn or pocketed

Whether it is semi-permanent
Fabric left rigged through a winter takes more UV and more wind than one rolled away. Say how it is used and we will advise on the colour and weave.
