Frequently Asked Questions
Will adding a privacy screen stop my shade sail from flapping?
A privacy/windscreen reduces the gusts that reach your sail and can significantly cut down flapping when mounted as a leeward barrier or behind posts. For best results combine the screen with proper tensioning hardware (turnbuckles, straps) and corner reinforcement — the screen alone helps, but it’s most effective as part of a system.
How tight should I tension a shade sail to prevent flapping?
Tension enough that the fabric is flat without wrinkles at rest; corners should be under steady load but not overloaded. Use turnbuckles to fine-tune tension and consider a small inline shock absorber or elastic damper to handle gust spikes. Avoid over-tensioning which can stress fixings and corners.
What hardware reduces vibration and noise best?
Stainless steel turnbuckles combined with short elastic dampers or marine-grade springs are ideal. They let you set high baseline tension while the damping element absorbs sudden gusts, preventing the repeated snap that causes noise and fabric fatigue.
