An inverted roof with mineral wool

Eighteen months’ monitoring is reported of an experimental roof on the building physics laboratory of the Catholic University of Leuven, Belgium. The existing lightweight roof with roofing felt finish, built some twenty years before, was covered with water‐repellent mineral wool slabs, of which only the edge slabs were bonded. The results showed poor water‐repellent quality of the MW slab, leading to a changed formulation with better performance. Water ponding under some slabs produced moisture uptake within the slabs themselves, probably from interstitial condensation. Despite these faults, the authors suggest that the concept can be made to work, with good thermal performance. Prof. Hens is co‐ordinator of CIB W40.

建筑室内S带电磁污染控制板材的薄形化研究

本文报道了基于k／4型电磁波吸收原理,通过理论设计和模拟分析,以石膏板为介电材料,采用住相调制膜设计制备吸波体,成功实现了电磁波吸收体的薄化。研究表明,多边形及圆环形位相调制膜结构都可以实现吸收体的薄化和吸收宽化,但多边形效果更好。实验表明,环宽度15mm,间距为10mm的正六边形三环结构膜可以实现在2．2GHz附近,达到-25dB吸收,并呈现更大宽化,整体-10dB带宽达到70％且可减少介电层厚度15％。新材料可用于室内电磁环境的改善和污染控制。
