  • How long will shade sails last?

    All fabrics used in shade sails have a minimum working lifespan of 10 to 15 years.

  • How to ensure good installation?

    Shade sail’s proper installation basically depends on accurate measurements. If you’ve taken some accurate measurements, you’ll find that shade sails are stretched tight and they don’t sag upon installation. But, the smallest measurement errors may cause shade sails to experience unnecessary wear and tear.

  • How to measure shade sails for installation?

    Before installing shade sails, it is recommended that you take measurements carefully. You should consider the location where you’ll install shade sails and ensure to measure the things out properly. Other than that, you’ll have to determine the available attachment points during the process. If you did not find any, you will have to erect structures or poles to attach the shade sails.

  • Are shade sails waterproof?

    In general, shade sails are not waterproof. Although there are several available shade sails which are made to be waterproof, the idea of using shade sails is to offer shade, not protection from the rain. Shade sails offer a little rain protection yet water will still seep through when there is a heavy downpour.
