It Is

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.


Shape and function, calm, simplicity are the muses that inspired the new interior design radiators IT IS. Harmony, rhythm, balanced full and empty spaces, perfect proportions, and painstaking attention to detail make the IT IS architectural structure clean and readable, giving it a sense of freshness, cleanliness, and order. The simple and immediate IT IS design is distinguished by the material nature of its rectangular section cornice that frames the horizontal bars in a slightly retreated position. IT IS comes complete with its own exclusive towel holder and can be positioned wherever the customer desires.

Construction features

horizontal elements featuring rectangular tubes 60x20 mm section

side manifolds with a 70x20 mm squared section

(*) Thanks to the high performance of Irsap It Is radiators, the ideal Δt for low temperature projects is Δt at 30°C.

For Δt different from 50°C use the formula: Q=Qn (∆t / 50)n
