你先看看你現在的窗戶是什麽結構的. 是木框還是鋁框. 框子有沒有爛了. 下窗沿是否是13度傾斜的.有沒有爛. 窗框爛了你就得換整個窗戶.
Lowes那個是STORM WINDOW,是裝在現有的窗戶外防風雨的. 你應該換的是Double Hung Window. 如窗框沒爛可以隻換那兩片窗, 加上旁邊一對軌道. Vinyl costs $200-$300. Wood cost $300. Wood with vinyl cladding and wood with Aluminum cladding $300-$600 per window.
Installation is easy if you know how.
