A curb adapter is a custom-made apparatus that mates the new RTU’s layout with the old RTU’s curb, which remains fixed to the buildings. Curb adapters must be custom made to transition the air from the new unit openings to the old unit openings and to ensure the structural integrity of the whole system.

When a building is constructed, prior to the installation of the HVAC Rooftop Unit (RTU), the roof is cut, and a metal structure called a Roof Curb is installed. The roof curb is designed to support the weight of the unit, and to offer a means for contractors to connect the supply & return air duct work.

All Knockdown curbs are furnished with a full perimeter wood nailer. This wood strip allows the roofer to nail the roofing material up to the top of the curb when sealing the roof. Insulate the outside of the curb using rigid insulation between the roof material and the roof curb.

Can TPO be installed over an existing roof system? But once all the existing insulation and decking has been inspected and approved, a TPO system can be installed after an insulation board has been applied over an existing built-up roof system or another single ply membrane.
