标题：一种用于建筑物翻新的极高热效率和气密性幕墙系统研究和开发一种覆层系统，用于改进建筑结构，以减少能量损失并改善舒适条件。我们提出了一种热效率高的幕墙系统，可用于任何商业建筑，包括固定立面的框架。它解决了幕墙建筑中常见的金属结构立面存在的热桥和气密性差的问题。SAS和MagmaTech正在开发一种纤维增强聚合物（FRP /复合材料）拉挤型材系统，该系统能够支持一系列幕墙材料。该系统将允许结合上釉区域和非上釉区域，并具有可变的最终光洁度，以实现PassivHaus标准性能。该系统具有优异的节能潜力，并且作为“织物优先”方法是特别理想的节能措施。结构元件是FRP，因此具有非常低的导热性。事实上，常用的铝型材和钢型材通常具有分别为200或60倍的更大导热系数。复合型材将支撑现有结构并将其连接到高度隔热的窗户（U值为

TITLE: An extremely thermally efficient and airtight curtain walling system for building refurbishmenttResearch and development of a cladding system with a building scale demonstrator for improving building fabric to reduce energy loss and improve comfort conditions.We propose a thermally efficient curtain walling system that can be used in any commercial building comprising a frame to which the façade is fixed. It solves the problem of thermal bridging and poor airtightness which is acute with the very common metal structural facades of curtain walled buildings.SAS and MagmaTech are developing a Fibre Reinforced Polymer (FRP / composite) pultruded profile system which is capable of supporting a range of façade materials as curtain walling. This system will allow a combination of glazer areas and non glazed areas with a variable final finish to achieve PassivHaus standard performance. This system has excellent energy saving potential and as a “fabric first” method is a particularly desirable energy saving measure. The structural elements are FRP and therefore have a very low thermal conductivity. Indeed commonly used aluminium and steel profiles will usually have greater thermal conductivity by a factor of 200 or 60 respectively.The composite profiles will support and connect the existing structure to highly insulating widows (U value of
