Ductwork is an ugly but necessary feature on many commercial rooftops. Sharing the project’s roof plan with a project manager is the best way to find a screening solution that will be able to conceal HVAC units and ductwork effectively. Most popular styles include post mounted or unit attached screening systems.
Post mounted screening offers a solution to enclose any sized roof equipment, unsightly elements, and ductwork all in one enclosure. However, these systems require you to disrupt the roof membrane. Putting holes in the roof and welding in steel posts requires multiple subtrades and is often a costly solution, especially when it comes to a fully completed structure vs a new build.
Envisor® Unit attached screening systems offer municipal code compliance with easy installation and no roof membrane disruption required. The system is designed to mount to the HVAC unit, keeping the curb clear so in some cases, ductwork can pass underneath without disrupting the screen. However if needed, here are three ways unit-attached screening can be easily adapted for ductwork:
1. Partial Screening
Depending on the line-of-sight requirements for the project, unit attached screening has the option to only screen what you need. 1, 2, or 3 sided screening can block HVAC units from public view while allowing ductwork to attach as needed to the back of the units.
2. Removing Panels
Unit attached screening offers a modular system with sliding panels. For larger ductwork panels can be removed to allow connection to the HVAC unit.
3. Cut Outs
Small intrusions like pipes or ducts can be easily accommodated by cutting out part of a panel. This allows for the unit to remain fully screened without blocking access.
Envisor® screening systems offer a variety of options to accommodate any roof plan all while avoiding roof penetration. Discuss your roof plan with a project manager to find the best solution for your project.
