Resumen

La creciente demanda de materiales de construcción sostenibles en áreas urbanas requiere nuevos recubrimientos protectores de madera, que conservan el aspecto natural de la madera al tiempo que minimizan los periodos de mantenimiento. Este trabajo presenta tres procesos diferentes de modificación de superficies de madera y evalúa su efecto protector contra la intemperie después de la aplicación en una fachada de prueba de la Casa de Recursos Naturales ETH (HoNR), un living lab recientemente abierto ubicado en Zürich, Suiza. Se controló la decoloración después de la exposición al aire libre de las formulaciones mejoradas de revestimientos delgados de óxido de metal desarrollados en el laboratorio. Se hizo hincapié en recubrimientos casi transparentes y duraderos con propiedades hidrófugas para disminuir la decoloración debida a la luz ultravioleta y al ataque biológico. Esto debería conducir a fachadas de madera con una mayor durabilidad y, por lo tanto, impulsar una utilización mejorada de recursos renovables y de almacenamiento de CO2.
