In bustling commercial spaces and industrial facilities where machinery operates around the clock, achieving acoustic comfort might seem improbable. Yet Greenheck's ATIP series roof fan curb transforms this aspiration into reality. This innovative solution addresses two persistent challenges in mechanical ventilation: disruptive operational noise and the complexities of sloped roof installations.

Modern architectural design increasingly prioritizes indoor environmental quality, where ventilation systems play a crucial role. Roof-mounted exhaust fans, while effective for air exchange, often introduce undesirable noise pollution. These acoustic disturbances particularly affect noise-sensitive environments—corporate offices, healthcare facilities, educational institutions, and premium residential developments.

The mechanical vibrations and sound waves generated by conventional roof fans propagate through building structures, creating problematic low-frequency noise that compromises interior acoustic conditions. Greenheck's engineering team developed the ATIP curb system specifically to mitigate these transmission pathways at their source.

The ATIP series distinguishes itself through four key engineering features:

Traditional roof curbs require extensive modification when installed on pitched roofs, often compromising weatherproofing and structural stability. The ATIP's straight-edge design naturally conforms to roof angles, minimizing gaps and creating seamless integration with the building envelope.

Available with acoustic insulation thicknesses of 1", 1.5", or 2.5", the curb's internal sound-dampening materials significantly reduce noise transmission. This absorption layer effectively decouples mechanical vibrations from the building structure, preventing noise propagation into occupied spaces.

The curb's primary structure utilizes galvanized steel, providing exceptional corrosion resistance and mechanical durability. This material selection ensures long-term performance in demanding outdoor environments exposed to UV radiation, precipitation, and thermal cycling.

The system incorporates a 2" flashing flange and built-in wood nailer, streamlining installation while enhancing waterproofing performance. These features create a continuous water barrier at the roof penetration, preventing moisture intrusion common in sloped roof applications.

Comprehensive technical documentation supports proper product selection and installation:

• Fan selection guides for system optimization
• Performance coating specifications for specialized environments
• Detailed warranty documentation
• Complete product catalogs covering roof curb systems

For building information modeling (BIM) and computer-aided design (CAD) workflows, the manufacturer provides:

• Revit model files (.RFA format)
• 3D CAD models (.DWG format)
• 2D CAD drawings for traditional design applications

The ATIP roof curb system represents a convergence of acoustic engineering and structural design. By addressing both noise transmission and installation challenges inherent to sloped roofs, this solution enhances mechanical system performance while improving indoor environmental quality. For architects and engineers specifying roof-mounted ventilation, the ATIP series offers a technically robust option that meets demanding acoustic and weatherproofing requirements.
