地毯在一个寒冷的板:蒸汽/ xps / double plywood
Background: the house was built in 1938 with slab poured between pre-existing foundation walls in 1954, and topped with vinyl asbestos tile. The slab does seem to stay dry all year, but nearby crawl space dirt is always a bit dark and moist. The slab is at grade. Quake contractors reported wetness at the bottom of each drill hole in the foundation nearby. Termites have been active through the slab. Radon is not a problem.
Climate: San Francisco Bay Area fog zone. It is a heating climate with chilly days possible all year, and only a few hot days ever.
我们想“热身”这个寒冷的地下室地板，将其变成卧室。我们完全知道没有真正的“好”选择。
We have about 2.5″ of space to play with:
————————————————————————————————————–
Option A:
多蒸气屏障，木制卧铺拧入混凝土，胶合板上方，然后是地毯底层和地毯。刚性板填充木材卧铺之间的空间。
Option B:
Epoxy top coat over the existing tile, cork on top of that, then permeable industrial carpet.
Option C:
XPS/EPS board on the slab with taped seams, two staggered layers of plywood floating on top. Then underlay and carpet.

所有选项都通过基础进行了一些热桥，这些桥梁在平板上方上方零至八英寸。房间约为10'x 10'。第二个类似的房间为8'x 15'。

But would love to hook up with actual examples of the techniques in action. Do they really work in real life?

Bryce,
I'm a little confused; you say that "The slab is at grade, " but elsewhere you refer to the slab as "this cold basement floor." So which is it -- a below-grade basement slab or a slab on grade?
无论如何，我建议您使用选项C。可以通过在混凝土板和XPS泡沫之间包括凹痕垫或schluter ditra来改进此组件。
是的，它将起作用 - 只要您的平板没有水分感染事件。
Martin: the cold room is slab on grade.
The other half of the house shares the same grade, but is foundation/cripple wall.
Bryce,
使用选项C。但是您可以考虑将胶合板通过泡沫拧紧到下面的混凝土，而不是将胶合板浮动。
选项C或变体是否在类似情况下工作，除了房间有可能从上方使用大量水，例如厨房，浴室或洗衣房吗？
我对选项c的变体很幸运。
Diamond ground the existing slab to creat a good bonding layer. In your case this may not be possible due to the asbestos tile.
Used a bostech concrete sealer vapor barier
Covered the floor with Poly taped at all seams (I prefer the dimpled mat but the client did not)
Installed 1/4 inch cork then laied a floating wood floor
Additionally I installed a slab depreasureization system similar to the ones recomended for radon.
Humidity in the house before the system was 58 to 60% after the system to remains under 48% in most cases.
What type of floating wood floor did you install? Our contractor is mostly worried about expansion/contraction in the larger room. We're looking at making the subfloor two layers of plywood, overlapped, but screwed only to each other. The contractor is used to tongue and grove ply.
What about the edges? What sort of detail should go around the edge of the room at both the foam and plywood layers (for Option C)?
Ok, we're down to doing it. Which option do you recommend:
A）Dimple Mat，XPS多层或带胶带接缝的EP，边缘泡沫。
3/4 T&G plywood, screwed through foam to floor. This is semi-permeable.
b）带有胶带接缝的XPS或EP的多层，边缘处有泡沫。
Double ply screwed to itself, and friction fitting onto the foam. This is less permeable, any moisture will rise to the bottom of the foam.
我们的平板比我们想象的要湿。如果我将塑料放在附近的泥土爬网上（在同一海拔处），我会得到水。向下钻大约4英寸后，它会钻入基础上。现在的平板始终干燥到现在的触摸，并且在我们已卸下的石棉瓷砖下是干燥的。
Just my take on finish floor. Carpet would feel warm. Engineered flooring works well in your situation. Open packages, open stack and leave for two weeks. I have 4000sqft stapled down that is flawless.
您的大多数地板隔热想法应该可以做到。这是另一个。一层泡沫胶带，一层Pt 3/4“胶合板，胶合胶带，胶带或不胶带，3/4 T＆G胶合板胶和螺丝，然后是ROSEN纸，然后是工程地板钉在下面。或地毯。
好的，看起来我们正在登陆：
Dimple Matt或Schluter Ditra取决于身高，胶带
xps taped, with good foam at the edges
3/4" T&G glued.
地毯底漆
没有螺钉

还有其他人有一个关于地板不起作用的故事吗？为什么？
