Résumé en anglais
The design and structure of the 120-year old Renwick Gallery of Art in Washington, D.C., are described. The nature of the materials composing the façade, and the deterioration processes to which they have been and are subjected are detailed. A previous attempt at restoration was unsatisfactory due to the sealing of the surface of the porous stone, and to a mismatch in thermal properties between the stone and the resinous additions. The principles and strategy of a proposed new restoratiion undertaking are discussed.
