院使用绝缘混凝土模板（ICF）系统字面上具有嵌入墙壁结构的一部分的绝缘建造。该系统创建具有高耐热性，与R-值通常高于R-17的壁。尽管ICF家庭使用的混凝土建造，它们看起来就像传统的坚持建造的房屋。
形成大部分的混凝土被组装在该领域，并且允许浇铸的现浇混凝土来被塑造成用作结构构件板，梁，柱，地板和墙壁。 Just about any material can be used to create a form, but traditional wood forming and modern pre-fabricated panel systems are the most common types of formwork for cast-in-place concrete. The design of a forming system must consider the basic geometry of the concrete to be formed, the weight of the concrete during placement, the lateral loads (wind forces) and the methods for attachment for additional concrete pours and/or future material attachments. In more complex concrete projects, shoring or falsework is sometimes required as support or scaffolding for the formwork to ensure that the formwork can support the loads and stress being applied by the concrete.
