Architectural ventilation should work beautifully — and visually disappear.
Our new Ventmann landing page explores frameless plaster-in MVHR ceiling diffusers designed for high-end residential, Passivhaus and commercial projects where conventional plastic air valves simply don’t fit the design intent.
Made from natural gypsum, Ventmann diffusers are plastered into the ceiling or wall and painted with the surrounding surface, leaving only a clean architectural slot visible.
✔ Frameless plaster-in finish
✔ Designed for MVHR supply and extract
✔ Natural gypsum construction
✔ Paintable to match the ceiling or wall
✔ LINE and CIRCLE diffuser options
✔ Coandă-effect airflow distribution
✔ 5-Year Warranty
✔ Next-day UK delivery available on selected products
✔ Free airflow calculations and technical support
Whether you’re an architect, MVHR installer, M&E contractor, developer or homeowner, Ventmann provides a more architectural alternative to traditional ceiling valves.
