SpiroFlex wall rosette Ø100 mm painted white SX-WO100R

SpiroFlex wall rosette Ø100 mm painted white SX-WO100R is a circular finishing flange designed to close and tidy wall penetrations for ventilation and exhaust ducts with a nominal diameter of 100 mm. The painted white surface provides a neutral indoor appearance while the simple geometry ensures compatibility with standard round ducts and grilles. The rosette serves as a visible trim that masks gaps between the duct and the wall and helps direct airflow components neatly into the interior or exterior opening.

Advantages

The SpiroFlex wall rosette is made for easy installation and a uniform visual finish: its painted surface resists minor scratching during handling and blends with most light-coloured interiors. The compact circular shape provides a consistent seal around the duct edge, reducing visible gaps and simplifying wall finishing. Its materials and design are suitable for residential and light-commercial ventilation applications where a tidy termination of round ducts is required.

Suitable for

• Finishing 100 mm round ventilation or exhaust ducts in walls
• Concealing gaps around wall penetrations in kitchens, bathrooms and utility rooms
• Residential and light-commercial HVAC and extractor fan installations
• Locations where a painted white visible flange is preferred for interior aesthetics

Key specifications

• Nominal diameter: 100 mm
• Shape: circular rosette / flange
• Finish: painted white
• Intended use: indoor wall termination for ventilation/exhaust ducts
• Compatibility: designed for standard 100 mm round ducts and grilles

How to use

Position the rosette over the round duct where it exits or enters the wall, ensuring the opening aligns with the duct axis. Slide the rosette into place so the inner edge sits closely around the duct pipe, then secure it to the wall surface using appropriate screws or adhesive depending on wall material and installer preference. Apply sealant between the rosette and wall if an airtight or watertight closure is required. Clean the painted surface with a soft, damp cloth to remove dust after installation.

Usage recommendations

For best results, check that the wall opening matches the rosette diameter and that the duct end is trimmed squarely. Use silicone sealant rated for indoor ventilation applications to improve air-tightness and reduce noise. Avoid abrasive cleaners on the painted finish to maintain appearance.
