Re: Visqueen in crawl space replacement
I agree with CyFree. I actually wrote an article on crawl space science that discusses issues with traditional systems versus closed, conditioned systems. There are a lot of advantages to closing and conditioning your crawl space, if it is done correctly. If something is utilized the wrong way, if an element of care isn't given to a control mechanism, or if something isn't installed adequately, any remedial activity performed in your crawl space may be in vain. It is best to seek professional assistance. Always look for a spe******t with the proper insurance; one that can explain the details of their system in a way you can understand; one with a warranty; third-party accreditation/certification is preferred; and someone whose system addresses all elements of thermal, humidity, conditioning and moisture control.
