@andersen_windows: Flashing details make or break a window install. @northernbuiltpro shows us how to properly flash a bucked-out opening to accommodate exterior insulation for our 400 Series window. Get it right the first time: flash bottom to top, lap each layer over the one below, and make sure your WRB integrates cleanly into the drainage plane before the window goes in. 🙌 #AndersenWindows #WindowInstallation
