Wind & Seismic Load

Severe wind loads or seismic activity occurs in many areas in the U.S. Thybar seismic curbs for rooftop HVAC's are specifically designed to withstand these forces. Compliance verification and calculations are performed by a Licensed Professional Engineer (P.E.). This includes all 50 states.
