Vital Louvre Series

The ‘jewel in the crown’ of the INNIVATE performance Louvre system is the Rain Defense and VITAL series Louvres. Proven under test to resist rainwater entry whilst being subjected to high airflows, the twin blade horizontal and the triple blade, vertical Louvre systems are the perfect solution where the restriction of water entry is critical whilst a good level of airflow is required.

The VITAL series with its ‘chameleon like’ architectural mesh treatments provides a welcome change for the designer to incorporate performance Louvres into this façade without compromising the visual aesthetic.
