Hello

Feeling green in every way here. I’m in Seattle renovating a home I bought last November and seeking a strategy for insulation/ventilation. I will be installing and budget is a concern – but I also want to do it right and am a meticulous worker. There are multiple layers of cedar siding on the house and shiplap sheathing. There is no insulation on the main floor and shiplap on the inside of the studs covered with wallboard.

The half story/attic was finished at a later time; is insulated and where all the bedrooms will be located. The bedrooms are all flanked by attic space we intend to use for storage. The attic contains old rock wool which has disintegrated and the majority of insulation is old foil faced fiberglass batt both of which have sagged or fallen. The rafters are 2 x 4’s – 24″ on center.

如果3“多异氰尿酸盐是椽子之间更换绝缘的好选择，我感到好奇。屋顶跳过护套，所以我不确定最好的安装选择。屋顶上有3个蘑菇通风口，在休眠者附近有几个开口，我需要由于过去的松鼠/啮齿动物入口而需要修补。也不确定这些通风口是否足够或必要。山墙上的窗户末端具有一点模具，因为前任所有者将浴室放入主板上的浴室，进入阁楼空间！这将被解决，以发泄侧面以及获得新的炉子系统。谢天谢地拿出一些覆盖模具，似乎仅限于靠近他们发泄的窗口区域。我的主要目标是正确的绝缘并创建一个不促进模具的系统。我的家人将在未来几个月内进入。

I would like to insulate the stud walls between the attic storage and bedroom space and have contemplated using batts. For the main level downstairs I’m not sure whether I’ll use rigid or batts. I’ve considered taking out a couple courses of shiplap, tucking in batt, nailing back down the shiplap and covering it with sheetrock. Sorry for the long winded post but I wanted to paint an accurate picture.

Cheers and Thanks
