Our manufacturing plant and general offices are located in Ocala, Florida where we occupy a 225,000 sq. ft. facility built to our specifications in 2006. CWS produces both vinyl and aluminum window and door products which are distributed throughout the Southeastern part of the country. We maintain our own fleet of trucks and deliver to most markets in Florida twice a week and out-lying areas once a week.
