Why is there condensation in between 1.5" polyiso board and roxul insulation?

Tyler Norrie Feb. 9, 2021Last updated: Feb. 12, 2021

嗨，伙计们，我来自加拿大，我最近完成了研究和绝缘我的地下室。我用了一个半英寸的polyiso板绝缘粘在墙上与粘合剂，我留下了半英寸的缺口在所有的板周围喷洒泡沫。在墙的前面，我买了一个框架来做墙壁和绝缘的Roxul绝缘球拍，我今天去做一些电气工作，并收回了一个浴缸，注意到有一堆冷凝和一点模具之间的蝙蝠和polyiso。我做错了什么吗?我地下室的湿度是45%。
