We are closely monitoring the Coronavirus outbreak and are proactively managing any potential impact on our ability to supply you while maintaining a safe work environment for our employees. The current assessment by our global team is that our ability to maintain adequate production levels and service to our customers is not in jeopardy.

Our plants remain in full operation and our business units and associated manufacturing facilities have met the criteria of an essential business as outlined in paragraphs 9 and 12 of the Ohio Stay at Home order from the Director of the Ohio Department of Health issued March 22, 2020. Our Tremco Construction Products Group staff (Tremco, Dryvit, Nudura, Willseal, WTI and WTC) who are not essential to production, will be working remotely, and will stay connected to one another and to you. Please continue to reach out with questions by email and phone during normal business hours. In addition to remote working for all non-essential staff, other precautions that we are taking:

  • Banning all non-essential work-related travel
  • Increasing cleaning and sanitization of high touch areas
  • Banning all non-essential outside visitors; for essential visitors such as contractors, enacting policy for screening and/or temperature scanning


As the situation with COVID-19 evolves, our plans may alter too. As we work together through this unprecedented event, we will continue to provide the strong support and service you have come to know and rely on for your business.

Please know that we are thinking of you and hope that you and your families stay safe and healthy during these uncertain times.

Thank you,

Tremco Construction Products Group
