The term for all organisational, constructional and technical measures designed to prevent the outbreak and spread of fires. This includes the compliant safeguarding of pipes and ceiling feedthroughs.
There are specially engineered fire insulation elements for concrete surfaces and steel trapezoidal-profiled roofs. The basic operating principle is always the same.
Fire insulation elements fitted with a swelling agent (material which foams in case of fire) ensure that plastic roof drains safely are sealed in the event of fire.
The fire resistance class of a component provides information on how long it can withstand a fire. The classification is defined in the standards DIN 4102-2 and DIN EN 13501-2.
Within the context of preventive fire insulation, plastic floor drains with a vertical outlet are regarded as pipe / ceiling feedthroughs that require sealing off. Otherwise, in the case of flats roofs, the fire can jump to the roof via the roof drains. In order to prevent this, it must be possible to professionally seal all feedthroughs of this type in compliance with the pertinent standards.
The same applies to floor drains. In this case, flames and smoke can spread very quickly via the wastewater pipes and set fire to further storeys. You will find more on the subject of fire insulation for floor drains here.

The industrial construction directive (IndBauRL) regulates the minimum requirements for fire insulation of all industrial buildings. The IndBauRL becomes generally binding with the publishing in individual federal states in the field of the Model Administrative Regulation for Technical Construction Rules (MVV TB).
Industrial buildings which meet the requirements of this directive comply with the safety objectives of the Model Building Code MBO §14.
The industrial construction directive (IndBauRL) regulates the minimum requirements for fire insulation of all industrial buildings.
Is published by the committee of ministers and senators of the 16 federal states responsible for urban development, construction housing (ARGEBAU).
MVV TB represents an important addition to the Regional Building Codes (LBO). The Regional Building Codes regulate planning, dimensioning and implementation of structures and the use of construction products. They also formulate general requirements which are put into concrete terms by MVV TB and clarified with reference to the valid technical rules.
DIN 18234 defines constructional fire insulation measures for large area roofs in case of exposure from below. DIN 18234 is broken down into four parts:
This standard refers to the fire behaviour of components and materials. It defines the fire resistance classes of materials to be used in house technology and how the components and materials are to be tested.
Fire insulation includes all measures that contribute towards the prevention and control of fires. Because this is a broad and complex field, different types of fire insulation are divided into the following categories:
As per DIN 4102 and DIN EN 13501, building products are divided into different classes, depending on how long they retain their functionality when exposed to heat.
