    • The fenestration structures include external frame segments facing the interior and exterior surfaces of a building wall, and an internal frame segment “sandwiched” between the external frame segments. The external frame segments are made from a relatively hard, dense and/or resilient material, such as hard wood, while the internal frame segment is made from paulownia which is a moisture-resistant, dimensionally stable thermal barrier material. The external frame segments therefore provide durable and attractive exterior and interior surfaces of the fenestration frame, while the internal paulownia segment provides superior resistance to thermal transfer across the frame, while also remaining dimensionally stable across a variety of moisture and temperature levels. Internal paulownia segments may be positioned around the entire periphery of the fenestration frame to create a comprehensive thermal barrier.
    • 开窗结构包括面向建筑物墙体的内部和外部表面的外部框架段和“夹在”外部框架段之间的内部框架段。 外部框架段由相对硬,致密和/或弹性的材料(例如硬木)制成,而内部框架段由泡桐制成,该泡桐是防潮,尺寸稳定的热障材料。 因此,外部框架段提供了开窗框架的持久和有吸引力的外部和内部表面,而内部泡桐部分提供了优异的抵抗框架的热传递的阻力,同时在各种湿度和温度水平下保持尺寸稳定。 内部泡桐节段可以围绕开窗框架的整个周边定位,以形成综合的热障壁。
