Bromley School found that the Dorgard unit helped his school with easier accessibility, ventilation and compliance.
Since installing Dorgard we fully conform to fire regulations and there is much more space through the corridor so pupils can move about more easily. The fire doors are fully opened against the wall now and stay there. Dorgard makes life easier for everyone.

We now have a Dorgard on every fire door. Fireco has always provided a superb service, from the day I placed the order through to delivery. Our caretaker finds them straightforward to fit so installation causes no no disruption to the school day. I have recommended them to other colleagues and would recommend them to anybody.
