Performance of thermal break strips in lightweight steel framed partition walls
Abstract
<jats:p>En este trabajo, se midió la resistencia térmica global superficie-superficie (valor R) de diez configuraciones diferentes de tabiques interiores LSF en condiciones controladas de laboratorio. Las pruebas de laboratorio se llevaron a cabo utilizando un aparato de caja mini caliente con un conjunto de dos cámaras climáticas, siendo el rendimiento térmico de las paredes LSF medido utilizando el método de medidor de flujo de calor. Los resultados experimentales se compararon con simulaciones numéricas de elementos finitos. Se evaluaron tres materiales de tiras de rotura de puente térmico (TB) y tres ubicaciones de TB y se compararon con el rendimiento térmico de una pared de referencia sin tiras de TB. En cuanto a los materiales de las bandas de rotura de puente térmico, se llegó a la conclusión de que el mejor rendimiento térmico se obtiene con el aerogel. En cuanto a la ubicación de las tiras TB, la aplicación en el lado interior o exterior presenta rendimientos muy similares y la aplicación en ambos lados del montante de acero muestra un aumento significativo relativo del rendimiento térmico. El espesor de las tiras de TB también tiene una influencia significativa en la resistencia térmica de la pared.AbstractIn this paper, the overall surface-to-surface thermal resistance (R-value) of ten different configurations from interior partition LSF walls were measured under controlled laboratory conditions. The laboratorial tests were performed using a mini hot box apparatus with a set of two climatic chambers, being the thermal performance of LSF walls measured using the heat flux meter method. The experimental results were compared with finite element numerical simulations. Three Thermal Break (TB) strips materials and three TB locations are assessed and compared with the thermal performance of a reference wall without TB strips. Regarding the TB strips materials, it was concluded that the best thermal performance is achieved by aerogel. Considering the TB strips location, the application inner or outer side, presents very similar performances and the application on both sides of steel stud shows a relative significant thermal performance increase. The thickness of the TB strips also has a significant influence on the wall thermal resistance.</jats:p>
