长期读者..第一次海报

我目前在气候区4中翻新1941年砖块Cape Cod复苏家庭，涉及在家庭后部的碰撞时解决一些现有问题。尽我所能，我可以告诉空间最初是一个无条件的太阳室，建造在一个高架的混凝土板上，坐在房子的成品地板下方约5-1 / 2。板块下方是一种未经辩护的爬行空间，可以通过部分完成的地下室的开口进入。爬行空间在污垢上具有蒸汽屏障和喷涂到混凝土表面（垂直基础壁和水平板底部）上的几英寸闭孔。在多年来，以前的房主试图通过在混凝土板上添加枕木来调节空间，使其与主房子带电水平，通过轮辋托梁进入睡眠空腔并在地板寄存器中终止它们。

Even with the added air conditioning/heat from the forced air system, the room is still quite uncomfortable during the as the wall/roof insulation is very poor and there is no thermal break between the slab and the space above. The initial plan is to tear the space down to the studs and address the roof/wall insulation as well as new windows and door. However I am struggling to come up with a gameplan for the floor. Looking around on this website and others it seems like the typical way to address a slab on grade is to lay down a vapor barrier and building up the floor with EPS foam board and pressure treated lumber. In my case I have the added complications of the ductwork and the crawlspace below. I am worried about doing something that might trap moisture in the floor or walls.

我想在最好的行动方面获得一些意见，以帮助解决与混凝土板的一些挑战。我意识到陷入困境，重建它是最好的，但这在这一点上不是经济可行的选择。

我试图将草图放在一起，帮助说明一些现有的条件。

任何投入将不胜感激。
