DIY,升级屋顶通风窗 (upgrade vent on roof)

[stevenw]

这是升级前后的图片。中间的升级了，两侧的要封起来。

原因：新房第一个冬天的一天早晨，发现Attic中有冰（半天后消失）。
所以天暖后加厚了 insulation 并换了 Vent.

希望对大家有帮助。

Are you sure only one vent is big enough for your attic air circulation?

It is 3 tire (function like 3 bigger-vents).
Original vent is 9" X 9" size, this one is 12" X 12"
It is said good for 3000 sqft house. seems a over-kill.
