“After extensive research on exterior insulation for my 1970s Berlin home, I selected these XPS boards primarily for their documented moisture resistance and compressive strength. The precise sizing facilitated a smooth installation process. Following one winter, the interior is noticeably warmer and drier—we now rarely use the fireplace. Most significantly, the persistent dampness in the basement walls has completely resolved. This investment has proven its value.”
