The Mold Explosion: Why Now?

Posted on Dec 18 by Christina Glennon

Abstract

Mold comes from moisture problems. So where do moisture problems come from?

Today's houses seem highly susceptible to mold. Building scientist Joseph Lstiburek explains why: wood products that can't tolerate mold; houses that don't dry out properly; hollow walls stuffed with insulation; and how the way residents use the mechanical systems affects the house's envelope. Lstiburek says that the fix to mold problems is clear: Water problems must be repaired quickly to prevent water from entering today's high-performances houses. The article includes sidebars on whether moldy framing lumber can cause rot, how mold can make residents sick and how to remediate a mold problem.
