FAQ

Choose a category

Can I install a ladder on your smoke vent models?

We do not recommend installing permanent ladders on our RSL-R, RLB-R, or other smoke vent models, as they may impact the aerodynamic and free areas, potentially affecting performance.

Which version of EN 12101-2 are Sertus natural smoke vents CE marked to?

Sertus natural smoke vents are CE marked to EN 12101-2:2003. Although a 2017 version exists, it has not been ratified or published in the Official Journal of the European Union (OJEU), so manufacturers cannot CE mark to EN 12101-2:2017.
