In the current scenario, our well-being and health (antibacterial) have become central concerns in our society. NIGHTFALL BLACKOUT FR combines the characteristics of its anti-bacterial finnish with another essential asset for our well-being: tranquility (sound absorber, causing less stress). In addition to these features, its energy efficiency (thermic) stands out, being intended not only for the residential market but also for contract due to its fire retardant properties, being totally opaque (does not allow the passage of light) and guaranteeing total privacy of the spaces whether from our neighbors or from the passers-by on the street.
