Myron：我们将首先挂上这一部分天花板。在我们在框架上放置任何粘合剂之前，我们希望获得第一个面板的测量。这样它并没有得到我们的卷尺。我们已经有了衡量和切割的面板。现在我将继续前进并将干墙粘合剂放在上面。我正在将干墙粘合剂施加到每个椽子上，约为3/8英寸厚的珠子，一点过去，接缝会击中，一直到底板。干墙粘合剂实际上增加了一点剪切强度并减少了我的干墙中的紧固弹出，但它也将有助于密封这些海湾，因此可以减少空气泄漏可能从一个海湾到下一个海湾。现在我们将在推动天花板之前尝试将它放在这个角落里。现在抵靠天花板。我们会让它缓慢滑下。 Justin: When placing the sheets, be careful not to smear the caulk or adhesive too much.

Myron: I’ve been able to apply adhesive to each rafter, but at this little gap between the…
