At MOÑITA we have designed, manufactured and installed a multitude of Shade sails in playgrounds or public squares and we are aware of their advantages and design particularities. They are usually used to cover small or medium-sized surfaces, normally no more than 100m2, usually supported on masts that can be free-standing or tied with metal straps. Microperforated or mesh-type membranes can be used when what is mainly pursued is sun protection or use waterproof membranes to also protect from rain.
