寒冷地区坡屋顶建筑老虎窗的构造处理

老虎窗具有造型丰富、视线良好、物美价廉的优点，是目前民用建筑在坡屋顶常用的设计手段之一。塑钢窗采用PVC工程塑料制作，节能效果明显，是我国当前在民用建筑中大力推广的窗型。因为塑钢窗通常为单层框，缺少传统双层木窗的过渡温度区，有时会在室内墙体表面产生结露现象。老虎窗侧一般制做单侧保温，正面墙体的热工状况较差，因此结露的现象更加严重。做好老虎窗墙体细部的保温处理，选择良好的保温材料，是改变这种局面的有效手段。

Structure of sloping roof window in the cold area

Sloping roof window is the popular means of design in civil architecture because of the obvious advantages of plentiful sculpts, excellent view and the high quality with low price level. Made up of PVC engineer plastic,plastic\|seteel window is popularized in the civil architecture in our nation becase of the obvious effect of energy saving. But the plastic\|steel window is often single window frame without the temperature transition, which is common in traditional wood windows of double window frame. So the phenomena of dew is often occurs in the inner walls. Sloping roof window is often used by single\|layer for keeping warmth, with low thermal power in the front walls, so the phenomena of dew is more serious than the plastic\|steel window. Therefore, the following is the effective means to improve the above condition: improvenment of detail arrangement for better keeping warmth of sloping roof window in the walls, and the better choices of the keeping warmth materials.
