Norbulb – fire protection made in Germany
Hightech Glass Bulbs for Automatic Fire Sprinklers
Highly precise thermobulbs for maximum security
Today effective fire protection without glass bulbs is unthinkable. Glass bulbs are being used as thermally actuating release elements mainly for automatic fire sprinklers, but also for any other temperature actuated mechanism that operates fire fighting devices, such as fire doors, smoke and heat exhaust ventilation systems as well as CNG safety valves.
Glass bulbs are the perfect element for these applications. They are mechanically extraordinary stable and resistant to temperature shock. They do not suffer from corrosion or diffusion and do not brittle or age. Over the past decades hundreds of millions of glass bulbs have been installed worldwide and proven their dependibility by helping to save innumerable lives and reducing property damage drastically.
