The new Thybar Retro-Mate is custom made to adapt an existing roof to a new rooftop unit. The manufacturer claims that the product saves on time and costly roof reconstruction. The Retro-Mate is also designed to preserve roofing integrity, reduce system downtime, and to take advantage of existing ductwork. The company has a library of new and old rooftop specifications, which allows Thybar to design a matching Retro-Mate without extensive field measurements.
