Adopted in 2018, EN 17037 is the first European standard on natural light in buildings. It recommends minimum guidelines in terms of the amount of natural light to be achieved for building comfort. Beyond these quantitative recommendations, it also covers other aspects of natural light, such as exposure to direct sunlight, protection against glare and a view outside.
Numerous studies corroborate that daylight, when properly used, is irreplaceable. Nothing compares to or gives such a feeling of well-being as daylight. Some products on the market aim to exploit the beneficial characteristics of daylight, while avoiding its negative aspects such as glare, reflection on screens and uncontrolled overheating of a room.
Easy to install, blackout blinds are practical when using video projectors or to avoid reflections on computer screens, but using them entails suspending natural light and means compensatory artificial lighting must be used, while external sunshades regulate excess light without depriving the room of natural light and its physiological benefits.
Made of profiled aluminium blades, Airfoil® sun protection’s advantage is that it is modular and fully customisable. Fixed sun protection can be assembled on a projection awning, installed on the building’s façade (horizontal or vertical sunshades, blades flat or standing) or even corner-mounted on a projection awning.
RAL powder coatings are QUALICOAT and QUALIMARINE certified. Aluminium blades can be ovoid, commonly called aeroplane wing blades, or rectangular. To provide even better building performance, they can integrate soundproofing solutions or LEDs.
In terms of energy, whether blackout blinds or architectural sunshades, both solutions limit excess heat from sunlight and help limit the need for air conditioning. But unlike sun protection, blackout blinds require repeated human intervention, meaning that they cannot be considered a reliable and sustainable device.
