Most installations happen with at least one corner fixed to the wall, using the wall profile or wallkit. Sails can be fixed to any element that is strong enough (e.g. a tree). Every sail contains a storage bag and the necessary ropes. The size and form is a matter of personal taste and size of the area that needs to be covered. The Ingenua shade sails are to be used under normal weather circumstances and have a wind rating up to 50 km/h or 31 mp/h.
