A Thybar Retro-Mate is custom made to adapt your existing roof curb to a new rooftop unit. Company officials said the product saves time and costly roof reconstruction, preserves roofing integrity, reduces system downtime, and takes advantage of existing ductwork. A comprehensive library of new and old rooftop specifications lets the company design a matching Retro-Mate without extensive field measurements. Reduced engineering and construction time lets you bid more competitively.
