Thybar has introduced its new laser-cut, all-welded construction Retro-mate adapters. The company says the Retro-mate offers a cost-effective method of replacing rooftop HVACs. The old rooftop unit is removed, and then the Retro-mate is installed on top of the existing curb to adapt it to the new rooftop unit. The Retro-mate is factory prefabricated of heavy gauge galvanized or Galvalume steel. It includes 1 ½-inch and 3 pound insulation, transitions, baffles and structural supports that mate the new rooftop unit to the existing curb and ductwork.
