PEX tubing is remarkably tough once installed in Warmboard's modular channels and it tolerates the normal wear and tear of a construction site well. However, sharp objects like loose screws and nails can puncture the tubing, which is why we recommend keeping the job site free from excess debris. As an added precaution, some professionals use temporary masonite panels or thin plywood to cover high traffic areas during construction. Experienced Warmboard installers rarely incur tubing damage. If tubing damage does occur, it can be fixed in about 10 minutes time. More information on this topic can be found in our installation manual.
