Guest guest Posted August 25, 2005 Report Share Posted August 25, 2005 , I would like to give you the technical side of this type of insulation. But, I can't seem to find the info I had on it. Hopefully, someone will have the full knowledge of it. I can tell you though, that I was asked to assist with some trial studies on it. (I declined-didn't have the time) But, I do remember for some reason that this type of insulation will allow the mold to grow faster if it gets wet. They say that it is treated for mold growth, but the studies were not there to support the claims. I will look to see if I still have my IESO notes, there was a builder there that teaches with IESO, and he would probably be able to help. Let me look and see. Give awhile though. Maybe someone here knows, if not I'll try to get the info to you.

Guest guest Posted August 25, 2005 Report Share Posted August 25, 2005 , Something else I remembered being told is that the blown in insulation keeps the house extremely air tight, more so than regular insulation. I had looked into having it put in my home, but didn't because I just couldn't find the info. I wanted. You know having a home to air tight for us is not good either. I hope someone here is an expert on this type of insulation and can help. I would be interested in hearing about it.

Guest guest Posted August 25, 2005 Report Share Posted August 25, 2005 >>>>You know having a home to air tight for us is not good either.<<<< Hi , Having a tight home is no problem at all since every home should have an air exchanger installed which makes it completely a non-issue. Some air exhangers come with their own HEPA filter. Even not so tight homes should have air exchangers to keep the cold air from condensing where it leaks in. Air exchangers drain their moisture. The air exchangers are suppose to pressurize your home which in effect seals out a non-tight house. Plus fresh incoming air and outgoing stale air also removes/dilutes VOCs, carbon dioxide, etc. Fletch Quote Link to comment Share on other sites More sharing options...
Guest guest Posted August 25, 2005 Report Share Posted August 25, 2005 I,am a Sheetrock and painting contractor in Pensacola fl. 1 year after hurricane IVAN and Dennis we are still 2 years booked removing and replacing molded rock and insulation. Some of the worst devastation has been the never ending supply of " MOLD REDEMPTION " companies, scam artists, jack legs, fear mongers and down right thieves that blew into town after the storms. With every claim, magic potion and snake oil you can imagine. Some charging $20,000.00 to spray a house with what turned out to be $3 worth of bleach. Here mold grows on every thing, sidewalks , roofs etc. I happen to have replaced ceilings in houses that used the soy-bean based spray in Insulation you are asking about. And recently saw the process. (the claim) is the installation process involves heating the three part liquid (thus by proxie " killing " any bacteria) and expands 100x to form an air tight soy-Polly skin. The claim " mold won`t grow on plastic " The bad news is here in Florida mold grows on plastic, glass and even in the lungs of some of my customers. For what it is worth here is the product link. http://www.biobased.net/ beening on this board for 3 years and developing a water management system and working every day in homes and condo`s that are literally black with mold. I can tell you what I tell my costumers ; mold needs three things Food, water and temperature. Mold spores are everywhere. They are already in the Sheetrock. Ad water and mold blooms, feeding on the gypsum. The key is the water, the less time building materials are wet the smaller the mold impact. Fiber glass and cellulose insulation hold water allowing the spore`s Germinate into an out break. Filling the inner wall cavity`s with a water tight foam and maybe applying and anti-microbial (tem-loc) should greatly reduce the chance of mold forming behind walls. Water tight walls open up air flow and interior moisture issuse`s.

Guest guest Posted August 25, 2005 Report Share Posted August 25, 2005 Tom, Thank you for the info. You say: <Water tight walls open up air flow and interior moisture issuse`s. Could you please elaborate on this for me. What exactly do you mean?

Guest guest Posted August 26, 2005 Report Share Posted August 26, 2005 , There should be no problem installing foam insulation. By Code, you must install insulation, and foam is a much better choice, albeit more expensive, than fiberglass.The foam makes the wall more airtight and if there is ever a mold problem, air flows are restricted. You do have to be careful that the type of insulation does not off-gas. Corbond (closed-cell urethane) and Icynene (open-celled urethane) are both foamed-in-place and in my experience, stop off-gassing after a few days. WALLTITE Resin (manufactured by BASF) is another closed-cell foam has a foul ammonia smell (from dimethylaminoethanol) that can linger long after installation, so I would avoid this brand. Choose an open cell foam. Keep in mind that the most important details to keep water out of walls are adequate roof overhang (the more the merrier) and proper flashing details at windows and doors (especially the gable ends where there is no overhang to protect the siding). At most new construction, the window cap flashings are bent improperly upwards, channeling all water that flows down siding to the weak point of the window: the corner and casing joints. (I have investigated rotted walls at about 50 homes where the decay was attributable to incorrectly installed window and door flashings.) Make certain that all water is shed directly off the window and door flashings. Test this during construction, after the siding and windows are on, with water from a squirt bottle. The water should drop immediately off the window trim or flashing; if it travels to the sides and down the edges or disappears behind the window trim (worst case) you have a problem. If you have a deck, you must have a gutter over the deck to avoid splash that inevitably leads to decay. Good luck C.
