How to insulate garage floors using rigid foam and plywood prior to applying finish flooring.
Hmmm?? Suggest two layers of 1/2" plywood on top of XPS layed in opposing directions and screwed together --- this avoids holes through plastic into concrete floor and hopefully adds strenght to eliminate curling of plywood. Suggests 1/4" gaps at all edges. Not sure if it will work, but interesting to consider.
It's an old question asked time and time again, whether or not a stair stringer should sit on top of a landing or notch around it. My personal opinion is that it will always be better to set the stringer on top of something like a landing that will fully support it...
The Aprilaire Model 1750A Whole-House Dehumidifier is suitable for homes up to 2000 square feet. Model 1750A is the environmentally, chlorine free "greener" version of the Aprilaire 1750 dehumidifier. The 1750A dehumidifier runs on environmentally-friendly R-410A refrigerant and removes up to 90 pints of moisture per day from your home, allowing you to be more comfortable, while lowering the humidity, that you can raise the A/C temperature on your thermostat and still feel comfortable while saving on your utility bills! This intelligent unit can automatically sense when humidity levels in your home rise above a certain preset level, saving you money at all times on your electric bill. In fact, this system runs on less than 4.5 pints/kilowatt per hour, giving it an Energy Star rating that many other dehumidifiers don’t have.
The Aprilaire 1750A Dehumidifier can be applied in three methods of choice: Whole-Home, Spot, and Convertible. Click here for details of each method.
Iron Bacteria is "more prevalent in some areas than others. But it wasn`t as rare as everyone was saying. The biggest problem I see about iron bacteria is that our industry hasn’t even admitted that we have a problem. They will admit it is a “rare problem” but by doing so, they can exclude it as a problem that needs to be addressed. It is not so rare for the homeowner who has to deal with the problem. I feel it is my duty to the industry to declare that we need to deal with iron bacteria if we truly care about our customers.
Suggests 140+ degree water flush and / or Iron Out. Do not pump outside -- will kill grass.
Subtitle: Higher R-values and lower permeance make closed-cell foam a winner Images: Green Building Blog By Neal Ganser Replacing long-obsolete insulation materials with closed-cell or open-cell spray polyurethane foam is a big step...
"Although air leakage is a more important mechanism of moisture transport than vapor diffusion, it is silly to assume that the laws of moisture diffusion are suspended for open-cell foams. Because open-cell foam allows moisture to diffuse through it, it can allow condensation to form behind exterior sheathing in winter or behind a vapor retarder or wallpaper in summer."
The CDA research has shown that temperatures of open wires in attics can get perilously close to the 194°F limit. If the wires are buried in attic insulation, pass over light fixtures or, worst of all, are arranged in tight bundles, they get even hotter than if they’re out in the open air. Wires so hot you can’t touch them aren’t good.
A basement represents an entire floor of space in your home — space that many homeowners don’t use to its full potential.
Basements are ideal candidates for finishing space if you’re thinking of adding an additional living area. . . . The process is fast, and it upgrades both the energy efficiency and resale value of your home.
What follows is a brief overview of everything you’ll need to know about basement finishing — including how to prepare for basement remodeling, which products we recommend, and what you can do to add long-lasting comfort, convenience, and value to your home.

"Efflorescence is a common problem in concrete and masonry block foundations. The white fuzzy stuff you see along the inside and outside of your basement wall is efflorescence . . . . . . Although efflorescence is harmless, if it is left untreated the white salt crystals can become trapped on the inside of the wall causing spalling that could lead to major structural problems
A conventional chemical cleaner that has been used for removing efflorescence is muriatic acid in a mild solution, usually one part muriatic acid (hydrochloric acid, HC1) to 12 parts water. Several mild individual applications are better than one overpowering dose. Again, care must be taken to thoroughly presoak the wall with clean water and to thoroughly flush the wall of all remaining acids with clean water"

"There's a two-pronged approach for combating this problem. First, you have to have enough access to the French drain (i.e. the pipe and gravel) to flush the system out with hot water. We are dealing with bacteria so that means the water has to be at least 140 degrees to "pasteurize" it. However, this is not a one time deal; you can't kill off all of the bacteria. So the key phrase is "enough access." Which means our normal 1-inch gap that we leave between the wall and floor now has to be about 6 inches."
Option 1 -- "I just have regular carpet padding and carpet on top of it, I have had no problems with this setup and it has been 5 years. The carpet doesn't get cold and i live in michigan so its very cold in the winter season. If its not leaking then i would not worry about all of this other stuff . . ."
Option2 -- "I used the [subfloor] in my Michigan basement and really like the results. They get you up off the concrete so the room feels more like a regular room and not a basement. My old house had carpet/thick pad on concrete and it was always colder when you walked without shoes. And, while it isn't a lot, when the kids fall down there is more "give" ... I'm also more likely to lay down on that floor than the carpet over concrete floor.
"So, my opinion is if you are looking for more of a functional room that everyone will use just like a main-level room, then get the subfloor. If it's just an occasional room that won't be used to play in, entertain without shoes, etc. then you can get away without it."

"poly next to the concrete followed by 1" of XPS will be about as good as can be done. Minor amounts of water that wicks/seeps up the fastener holes can still easily dry through the XPS without creating mold conditions at the subfloor, and the high vapor retardency of the poly keeps the majority of the ground water where it belongs ( in the ground.)."
I just started finishing my basement and am curious on how to put a heat duct in the walls. Can I simply cut in a hole into the base vent and extend normal vent bought at home depot to the spot I want?
Some suggestions and some thoughts on code. Review before ducting!!
