Louvre roof pergola system


Comforting Reliability | High Quality | French Made | Unique Features

Since 2009, Biossun have been reinventing the art of outdoor living by creating new and innovative ways to enjoy nature. The louvre slat for shading isn’t a new concept by any means, but how the slat is positioned with moving sunlight is.

Their bioclimatic louvre pergola systems have been designed in the Isère valley, in the foothills of the Alps. Where their research, development and quality assurance teams work daily to innovate anticipating trends and working respectfully with nature.

Biossun was the result of a meeting of minds and the spirit of 3 entrepreneurs deciding to develop an innovative aluminium sun protection system with adjustable louvre slats.

Today, Biossun still only focus all their energies on the bioclimatic pergola louvre roof system and nothing else. With over 25,000 private customers and more than 3,000 commercial installations in the hotel, bar and restaurant trade, they are leaders in this field and have more to offer than most similar systems.

The BIO 120 and BIO 230 bioclimatic covers with intelligent integrated systems that offer users a choice between shade and sunlight, according to personal preference.

The special S-shaped slat design of Biossun bioclimatic patio and terrace covers allows for a tighter space in which air circulates, speeding up the air flow and drawing it upward. This exclusive Biossun design ensures temperature regulation that is clearly felt.

For the BIO 230 and BIO 120 bioclimatic models, you now have the choice between two types of aluminium blades: S-shaped or flat-bottomed, for a more stylish look with the same weather protection properties and natural ventilation effect.
