Fomatec

Dome Smoke Ventilation Hatch 

Effective Smoke Extraction with Natural Daylight

Fomatec is an insulated, electrically operated, and CE-certified smoke ventilation hatch for flat roofs. Its domed design with integrated light transmission combines fire safety with natural daylight, making it an ideal choice where both function and comfort are priorities.

The hatch is manufactured in compliance with EN 12101-2:2003 and is suitable for both smoke ventilation and comfort ventilation.

 

Purpose of a Smoke Ventilation Hatch

The purpose of a roof-mounted smoke hatch is to rapidly extract hazardous smoke gases in the event of a fire in buildings such as residential complexes, stairwells, warehouses, industrial facilities, or other structures.

 

Why Is Roof Smoke Ventilation Important?

Smoke hatches or smoke ventilators are a vital part of a building’s fire protection system. They are designed to open—either automatically or manually—in the event of fire, allowing efficient ventilation of smoke and hot gases from the building.

By quickly removing smoke, smoke hatches:

– Improve visibility in escape routes

– Reduce the risk of smoke inhalation

– Support firefighting and rescue operations

– Protect the building’s load-bearing structure from overheating, helping prevent collapse

 

How Does a Smoke Hatch Work?

Smoke hatches can be activated in several ways:

– Automatically via smoke detectors or fire alarm system

– Manually using a push button or emergency release

– Thermally, using a fuse link at a set temperature (not used in our hatches)

When opened, the hatch allows rising smoke and hot air to escape from the building.

 

Regulations and Compliance

In Sweden, the installation and use of smoke hatches is governed by the Swedish Building Regulations (BBR) and standards such as SS-EN 12101. A properly installed and maintained smoke hatch is often required for building permits and to meet insurance requirements.
