One Last Question: What About Interior Protection?


As a professional working in the commercial re-roofing business have you ever asked the question, "Are we going to recommend Interior Protection for this project?"


This is not your grandfather's type of drape and cover with canvas tarps or 3 mil poly from the hardware store. An Interior Dust & Debris Protec-tion System allows people to work and manufacturing to continue below AND the re-roofing project to take place - all at the same time.

Material View of Mold

First appeared in the ASHRAE Journal, November 2009.

Reprinted with permission. - Building Science Insights.

By Joseph W. Lstiburek, Ph.D., P.Eng., Fellow ASHRAE


Mold is pretty easy to understand.  No water no mold.  Any questions?  Well, there are a few.  For one we have more mold today, but we don't have more water.  What's with that?  We've always built outside out of wet stuff.  Concrete comes in a big truck and we "pour it."  We put "mud" in the joints  of gypsum board.  That hasn't changed.  The problem is that the same amount of water we've always had to deal with is hanging around longer and longer in building materials that can't take it.  We have more insulation  today and that reduces drying potentials because it reduces energy exchange.  That is one reason we have more problems with mold today.  The "more insulation" is responsible for the water "hanging around longer" part.  But there is another reason-the building materials "that can't take it" part.  We used to build out of rocks and 1,000 year-old trees.  Not any more and that is a big deal, as we will see.

Case Study - Dow Corning Solution

First appeared in Dow Corning's Silicone in Construction Magazine, 2002.

Built in 1965 of white precast concrete panels, the First National Bank of Mobile had a history of leaks and patchy repairs but Hurricanes Opal in 1995 and George in 1998 created major water intrusion issue.


It was estimated that the cost to just cut out the old sealant would be $700,000; however, a better idea was offered - Dow Corning 123 Silicone Seal.
