CEU DESTACADO

Soluciones competitivas, constructibles y completas que especifican el envolvente total en un mundo de ofertas bajas

Un impresionante 90% de los litigios en construcción están impulsados por la intrusión de humedad. Esa intrusión ocurre dentro de solo el 5% del área superficial total de la envolvente. El culpable siempre es el mismo: transiciones y penetraciones. El tejado debe hacer la transición hacia la pared, la pared debe pasar a la cimentación, las aberturas perforadas deben conectarse a la barrera de aire, el aislamiento debe instalar sobre la barrera de aire y el revestimiento ir encima... y así sucesivamente. ¿Cuál es el reto? Necesitamos que el envolvente funcione como un todo unificado, pero especificamos, diseñamos, licitamos, VE, instalamos e inspeccionamos en fases, lo que siempre implica múltiples fabricantes y múltiples oficios. La industria se está consolidando claramente en torno a las "soluciones de envolvente total" proporcionadas por tres o cinco conglomerados integrados horizontalmente, pero aún no alcanzamos el punto de inflexión: especificaciones/garantías de envolvente integradas. ¿Qué hará falta para hacerlo mejor?
