Frequently Asked Questions
Do these screens block all sunlight?
No — these HDPE screens typically block about 85–90% of direct sunlight and UV, which significantly reduces heat and glare while still allowing some light and air to pass through. That balance keeps patios cooler without making them dark and stuffy.
Will the included zip ties and grommets hold in strong wind?
The reinforced edges and rust-resistant aluminum grommets improve wind performance, but success depends on how tightly the screen is fastened and fence type. Many users recommend using longer or heavier cable ties or additional fasteners on very windy sites.
How do I measure for the right size?
Measure the length and height of the area you want to cover and add a small allowance if you need to tie or trim the screen. SUNLAX notes an elasticity-based tolerance (about 4 inches), so if you need a precise fit, choose a slightly larger size you can trim or secure tightly.
