When constructing a building, protection against fire is one of the key safety requirements. What is often colloquially referred to as a fire door is technically a fire protection closure. It fulfils a crucial task: in an emergency, it reliably prevents the spread of fire and smoke – for a precisely defined period of time. This saves valuable minutes that can save lives and protect property.
With Lindner fire protection doors, you can rely on tested quality, functional design and maximum safety. Our portfolio offers a large selection of fire protection doors that can be customised to your building project.
In modern structural and interior fit-out, structural fire protection is one of the most important requirements – whether in new builds, refurbishments or public buildings. Fire doors play a key role in this context and are, in technical terms, referred to as fire-resistant door assemblies. They are designed to prevent the spread of fire and smoke for a defined period in the event of an emergency. In doing so, they help keep escape and rescue routes usable, protect lives and property, and effectively limit fire damage.
The Lindner Group develops and manufactures high-quality fire protection products, including fire doors, which ideally combine functionality, design and safety. Whether for administrative buildings, industrial facilities, educational establishments or hospitals – we offer individually adaptable door solutions that comply with current standards while also meeting architectural requirements.
These doors are classified according to their fire resistance duration:
Depending on the area of application and the fire protection concept, different variants are used. T30 doors are typically suitable for corridors or offices, whereas T90 doors are required in areas with extensive technical installations or in industrial facilities.
Example: Our ATB-ADS 80 FR 30 fire door element provides optimum T30 protection combined with modern glazed elements – ideal for transparent interior spaces with high safety requirements.
In addition to fire protection, smoke control doors are essential in order to contain toxic smoke gases. These doors prevent escape routes from becoming smoke-filled and are commonly installed in stairwells or corridors. They must be self-closing and smoke-tight, so that smoke cannot penetrate through joints or door gaps.
In addition to fire protection, project doors often fulfil further requirements, such as:
These multifunctional door systems are used primarily in hospitals, hotels, educational facilities or office buildings. Our doors can be configured individually to suit each project – in terms of finishes, ironmongery, glazing or dimensions.
Our door systems are available as single- and double-leaf variants, can be installed flush with the surface, and can optionally support automatic door operators, panic/escape door hardware and access control systems.
