Western Sun Control, Clearances, and Fast Drainage
Western Sydney afternoons deliver heat and low glare that make patios and alfresco areas uncomfortable. A well planned shade sail fixes that. Place corners where people move freely, set clear height differences so water drains off the fabric, and keep edges away from gutters and lights. When anchors are solid and geometry is clean, the sail looks sharp, runs quiet, and lasts longer in local conditions.
What Good Alfresco Shade Looks Like
Start with the space you actually use. Map the dining table, the BBQ, and the path to the yard, then choose corner positions that protect those zones without blocking movement. Keep the lowest edge out of reach and away from doors and windows, and set taller corners on the hot western side to cut afternoon sun while keeping winter light where you want it.
- Prioritise seating and doorways, then protect the western exposure.
- Keep clear walk paths under the sail with no hardware in the way.
- Hold edges clear of gutters, lights, and downpipes to avoid rub points.
With these basics set, you get shade where it matters and a layout that feels open.

Fixing Points and Post Placement
Your sail needs anchors that are strong and well placed. If you plan to fix to a building, confirm structure behind fascia or beams, then allow space for turnbuckles to align with the pull. Posts take the load on open edges, so size footing depth to suit soil and span, and set posts back from door swing zones so people do not clip them when carrying trays. A small change to post location now often prevents future noise and wear.
- Align each anchor with the line of pull for smooth tensioning.
- Position posts to protect patios, furniture, and door swings.
- Keep a clean gap for hardware so fittings do not bind against walls.

Fabric Fall and Water Management
Sails should not hold water. Plan at least one high and one low corner, then add a gentle twist across opposite corners to avoid a flat plane. Aim the low corner toward garden beds or a drain, not across the doorway or main path. If the span is wide but heights are limited, two smaller sails often drain better than one oversized panel and make tensioning easier.
- Set distinct high and low corners on every sail.
- Use a visible twist to prevent pooling and flap.
- Direct run-off to safe, non-slip areas away from entries.

Common Layout Mistakes
Small errors lead to callbacks you can avoid. Equal corner heights create ponding. Corners pushed tight under eaves leave no room for hardware. Long spans without extra height sag in the middle and throw glare back at eye level. Edges too close to downpipes or wall lights rub in gusts and stain over time.
- Do not set all corners at the same height.
- Leave room for turnbuckles and shackles to work.
- Add height or split large areas into two sails.
- Keep fabric and hardware clear of anything that can rub.

FAQ
Keep it above head height and away from doors and windows, then raise an opposite corner to create fall.
Yes when the structure behind the fascia is suitable and reinforced. If not, we use posts sized for local wind and soil.
Often two sails give better fall and fewer rub points when heights are limited.
