Smoke ventilation hatches and systems

Tarvasovi manufactures aluminium and steel smoke ventilation hatches using Schüco and Jansen’s versatile window and smoke control systems. The range includes bottom-, top and side-hinged units, opening either inward or outward. All hatch types are supported by official test reports to verify conformity with the required standards. Our selection also includes smoke control panels, activation switches, locking motors, smoke detectors and various accessories, enabling the design of a complete smoke ventilation system using Schüco or Jansen components.

Smoke ventilation solutions based on actual needs

Tarvasovi uses the NRWG software to determine the most suitable and cost-effective smoke ventilation solution for each project. The software calculates the required actuator, its necessary force and the opening angle. It also automatically determines the Aa-value–the aerodynamically effective free area–achieved by the smoke ventilation hatch.

Auditing and oversight

Smoke ventilation hatches and windows have been subject to CE marking since 1 July 2013 under the harmonised product standard EN 12101-2. They fall under AVCP class 1, which requires system testing, external production control and third-party auditing. In addition, case-specific minimum/maximum dimensions and weight/surface-area limits must be considered for each opening type.

Tarvasjoen Teräsovi Oy has an agreement with VTT Expert Services Oy for external auditing and production oversight.
