Ventilation chimney
VENTOS X BITU UNI ALU
*Available to order.
The advanced Eurovent® VENTOS X BITU UNI ALU roof ventilation chimney has a ventilation cross-section of 170 mm and a connection diameter of 150 mm. It is made of high-quality plastic and features an EPDM gasket and a flexible FLEX 3D aluminium sealing collar with a thick butyl layer, measuring 400 × 550 mm. The design of the chimney supports ventilation by harnessing wind energy and ensures proper chimney draught. It features an anti-condensation system that drains condensate to the outside of the roof. The profiled cap prevents rainwater from entering the chimney. The inclination angle can be adjusted from 5° to 45°. It features a universal, flexible base for installation of the chimney, including on trapezoidal sheets. It is available in several of the most popular colour variants according to the RAL colour palette.

System products
To ensure maximum ventilation efficiency and airtightness of roof connections, Eurovent® VENTOS X BITU UNI ALU is recommended for use together with:
- Eurovent® system installation accessories, such as FLEX X, FLEXOS X and SEAL EPDM, which ensure a durable and airtight connection between the ventilation chimney and the roof covering;
- Eurovent® highly vapour-permeable roof membranes, which support proper ventilation of the roof slope and protect the roof structure against moisture;
- Eurovent® sealing and adhesive tapes, which protect installation areas against weather conditions and moisture penetration;
- Eurovent® roof communication elements, facilitating safe servicing and access to the ventilation installation area.
The use of complete Eurovent® system solutions ensures effective moisture removal, stable airflow and long-lasting airtightness of the entire roofing system.

GOOD TO KNOW
What is the benefit of the flexible UNI ALU base?
The aluminium collar can be shaped on site, making it easier to adapt to some profiled roof coverings, including trapezoidal metal sheets.
Does UNI ALU fit every trapezoidal metal sheet?
It should not be treated as automatically suitable for every profile. Before installation, check that the collar can be correctly shaped and sealed on the specific covering.
What is the role of the butyl layer?
It bonds the collar to a properly prepared covering surface. Bonding performance also depends on the substrate being clean, dry and in suitable condition.
When should a dedicated base be chosen instead of UNI ALU?
If a base explicitly matched to the specific covering model is available, it provides more predictable installation geometry.
Can the collar be stretched freely?
No. It should be shaped within the limits of its design, without excessive stretching or damage to the sealing layer.
