Ten years after its birth, add-On, the design radiator by the Italian company Tubes, is still an original architectural element that offers the designer innovative aesthetic and functional solutions. The model was designed by Satyendra Pakhalé for Tubes and its project is based on a form of 12×24 cm that can be freely combined, customizing the shape of the heater depending on the desires and aesthetic design requirements: add-On can cover a wall, completely or partially, becoming a decorative and architectural element in the room. Thanks to these features, the product received the Red Dot Design Award 2008 and is part of the permanent collection of the Centre Pompidou in Paris. More recently, in the context of the just ended International Art exhibition of the Biennale in Venice, add-On has been selected for the exhibition “Looking Forward. The evolution of the art of doing”.
