What kind of insulation do you recommend to put on my exterior sheet rock wall?

Uwe Thomas May 22, 2020Last updated: Sept. 29, 2020

我们住在加利福尼亚的圣何塞。我们的房子已经有50年的历史了，我想在我们的灰泥壁板(混凝土一样的材料，大约3/4英寸厚)外面增加隔热层。我在考虑安装大型隔热板(泡沫聚苯乙烯或类似)，类似于他们在欧洲各地使用的那种。我正在寻找一个指针在哪里开始和找到更多的信息。Thanks,

Insulating the exterior walls of older homes has to be done carefully so you don’t trap moisture.

我建议你使用一些矿物棉/岩棉保温材料，因为它们不会受到水分的伤害，水分会直接穿过它们。墙壁需要能够干燥，所以任何时候你添加墙壁，最好确保你只使用透气性产品。Here is our page onChoosing the best rigid insulation,
