At a home & garden show today, I saw a number of vendors pushing their
encapsulated crawl space, mostly CleanSpace brand. In some ways it sounds
attractive but they claim you need no vents and no dehumidifier. It seems
to me that with no air movement there will be inevitable humidity build up
due to small leaks, air conditioning ducts etc. and that the mold problem
could be increased rather than eliminated (dark, moist, little to no air
movement).

Does anyone have experience with these? Good or bad experiences? If so,
how long has it been installed?

Look at The Building Science Corporation web site.
This is * researched * informaition.
As a practicing architect, I refer to this information.
Your local climante has a lot to do with wheather or not this is a
useful approach.

There was a government study that said this worked better than ventilated
spaces since ventilation lets warm humid air in and water condenses out
under the house. You need a good french drain system for it to work
properly.

I am an AC contractor and about 20% of my business is crawlspace
encapsulation. I started doing it based on my own research long before
I ever heard the term encapsulation. I even had an article published
on it in an HVAC trade journal.

Here is a link to my article on Crawlspace problems

http://www.contractingbusiness.com/C...S=&NI L=false

It is kind of technical, but I hope it helps. email me at sixfoot7 at
sccoast dot net if you have any questions. Note: if you live in a
desert, ventillation works better, most anywhere else, encapsulation is
better.
