Helioflex is a sunlight reflection system for urban spaces and dwellings, a technological development with the goal of directing light in great quantities and at low cost to where previously it had been dark.
The dense development of inner cities leads to a social gradient of light: from the penthouse terrace to the ground-floor apartment on a rear courtyard. The sun reflector compensates for this gradient and reflects, together with the sunlight, also a connection to the outside world into formerly constantly dark spaces.
