While My Window Gently Weeps: Window Gasket and Weep Systems for Keeping Water Outside

Installing windows isn’t hard—you apply sealant to the back of the nailing flanges, pop it into the opening, secure with a few roofing nails and--if you’re into best practices--you go over all four flanges with housewrap tape. At least that’s what many of us learned 30-40 years ago (except for the tape part) and it’s still how most windows are installed. Why, if that system works, do windows still leak? Building science expert and educator Peter Yost joins us this week to discuss the science behind window installation. According to Peter, “Windows are complex elements of our building enclosures and their installation is just as complicated.” He will break down what that means and some evidence-based solutions.
