INTENSIVE VENTILATION INTENSIVE VENTILATION – NIGHT COOLING The building will cool down by ventilating with large flows of natural air at night.

These louvres are available in 3 variants: ∫ Type 431 – Excellent rain-repellant properties (class A: less than 1% water infiltration at high wind speeds) – Maximum airflow (physical free...

WATERTIGHTNESS TESTS RAIN-REPELLANT Renson® louvres are subjected to European testing (according to EN 13030: 2011) by the internationally accredited corporation BSRIA Ltd. During these tests, a louvre of 1m2, equipped with stainless steel mesh is exposed to downpours at a rate of 75 litres per hour and a wind speed of 13 m/second. The classification is based on the obtained results, i.e. the quantity of water infiltrating through the louvre. Attention: The “air speed” reference always indicates the air speed at the suction side. If a louvre is assigned to a watertightness, the class...
