Roof Vent Plate SpiroFlex 150, stainless steel, 2-way exhaust

SpiroFlex 150 Roof Vent Plate is a stainless steel rooftop exhaust component engineered for 150 mm duct systems. It creates a protected termination for ducts on roofs and delivers a two-way air outlet to facilitate ventilation and extraction. The unit's stainless steel construction resists weathering and supports durable rooftop installation in residential and light-commercial buildings where a compact, corrosion-resistant exhaust outlet is required.

Advantages

The stainless steel construction offers corrosion resistance and dimensional stability for outdoor use. The two-way exhaust configuration enables bidirectional air discharge while preventing direct ingress of rain and debris into the duct. The plate is designed for straightforward integration with standard 150 mm circular ducts and provides a low-profile rooftop termination that helps maintain finished roof appearance and airflow efficiency.

Suitable for

• Ventilation and mechanical extraction for homes and apartments
• Kitchen and bathroom exhaust systems
• Light-commercial ventilation outlets on low- to medium-pitch roofs
• Replacement or upgrade of existing 150 mm rooftop duct terminations

Key specifications

• Material: stainless steel, suitable for outdoor exposure
• Duct connection size: designed for 150 mm circular ducts
• Exhaust type: two-way outlet configuration
• Mounting: rooftop plate for fixed installation on roof surface
• Finish: metal, corrosion-resistant surface for long service life

How to use

Position the SpiroFlex 150 Roof Vent Plate over the prepared roof opening aligned with the 150 mm duct. Secure the plate to the roof structure using appropriate fasteners and sealants compatible with the roofing material to ensure a watertight installation. Connect the internal duct to the plate's circular outlet, verifying a tight mechanical fit and proper alignment to prevent air leaks. After installation, inspect exterior joints and internal seals and test the ventilation system for correct airflow and discharge.

Usage recommendations

For reliable performance, select fasteners and sealants that match the roof substrate and local building codes. Periodic exterior inspection and clearing of any accumulated debris will maintain airflow. When used with motorized extraction systems, ensure ductwork is supported and sized correctly to avoid excessive backpressure; consult ventilation design guidelines for airflow and noise considerations.
