Frequently Asked Questions
Do lighter colors really keep patios cooler?
Yes. Lighter colors reflect more visible and infrared light, which lowers the amount of heat absorbed by the sail and the shaded surface beneath. For maximum cooling, choose breathable HDPE fabric in a light or medium tone.
Are breathable HDPE sails waterproof?
No. Breathable HDPE is designed to let air and water pass through; that helps cool the area but means it won't shed heavy rain. If you need rain protection, look for a waterproof-coated fabric or design the sail with a steep pitch so water drains off.
What hardware do I need for a durable installation?
Use stainless-steel pad eyes, turnbuckles, snap hooks, and thimbles rated for outdoor use. While many sails include ropes, upgrading to stainless hardware prevents corrosion and gives better tensioning and longevity. Anchor points (posts, walls) must be strong and placed to maintain a tight installation.
