The cuts break the shape and make it functional for use but above all they accentuate the perceived value, making it three-dimensional and sculptural. The light and shadows reveal an intrinsic spirituality of the object. SEQUENZE is supplied with the innovative concealed hydraulic connection system installed directly in the company. Available in two models, SEQUENZE S and SEQUENZE L, with two thermal powers.

The Designer

Angeletti & Ruzza

A couple in both personal and professional life, Silvana Angeletti was born in Rieti in 1969. Daniele Ruzza was born in Rome in 1967. After graduating in industrial design, they began their partnership in February 1994 and opened their own design studio: angeletti ruzza design. They took part in numerous competitions, winning prizes and commendation. They live and work in Rieti and cooperate with numerous prestigious Italian companies. They have been collaborating with IRSAP since June 2006 and their research into proportion and linearity has led to three products that blend artistically into the home environment. SEQUENZE, a radiator that speaks a contemporary language, with a neat and simple form that fits natural into any architectural environment. Shape and function, calm and simplicity are the inspirational muse of the new It Is and M’ama thermo-artworks, made in 2017.
