A Thybar Multi-Zone Retro-Mate® is custom made to adapt the existing roof curb and zoning to new rooftop units. It saves time and costly roof reconstruction, preserves roofing integrity, reduces system downtime, and takes advantage of existing ductwork and zones, says the company. Thybar’s comprehensive library of new and old rooftop specifications allows it to design a matching Multi-Zone Retro-Mate without extensive fieldwork. Reduced engineering and construction time lets you bid more competitively.
