窗框材料的特性对窗户的性能有着重要的影响。窗户本身在决定建筑物的整体能源性能方面起着至关重要的作用。本文从可持续性的角度分析了四种不同的框架类型：铝，铝包木，聚氯乙烯（PVC）和木材。这些框架类型已经过各种参数的研究，例如：框架材料生产/提取和框架处置过程中的环境影响;内含能量、耐久性和使用寿命;以及框架的维护和修理。还讨论了价格比较和市场情景。已经发现，木材和铝包覆的木材窗户是可持续的产品，因为它们具有环境友好的特性，即，低能耗、低环境影响、更好的耐用性和更长的使用寿命。而铝和PVC框架具有较高的内含能量值和相关的环境影响。实际应用：在当今可持续发展意识的时代，窗户行业正在强调如何提高其产品的能源和环境性能。本文不仅对现代窗户制造商感兴趣，而且对客户也感兴趣，因为它解决了窗户的关键可持续性特征，即，能源和环境性能、耐久性和使用寿命以及维护和生命周期成本。
The characteristics of the frame materials have significant impacts on the properties of a window. A window itself plays a crucial role in determining the overall energy performance of the building. This article analyses four different frame types; aluminium, aluminium-clad timber, Polyvinyl chloride (PVC) and timber make, from the sustainability perspective. These frame types have been studied on various parameters such as; environmental impacts during production/extraction of frame materials and disposal of frames; embodied energy, durability and service life; and maintenance and repair of frames. A price comparison and market scenario has also been discussed. It has been found that timber- and aluminium-clad timber windows are sustainable products due to their environment-friendly characteristics i.e., low embodied energy, low environmental impacts, better durability and longer service life. While aluminium and PVC frames have high values of embodied energy and associated environmental impacts. Practical application: In the present sustainability-conscious age, the window industry is emphasising how to enhance the energy and environmental performance of their products. This article will be of interest not only to modern window manufacturers but also to customers as it addresses the key sustainability features of windows, i.e., energy and environmental performance, durability and service life, and maintenance and life cycle costing.
