System line penetrations
Under to current building regulations, buildings must be divided into fire zones of a certain size with walls and ceilings of adequate fire resistance. At the same time, those walls and ceilings contain numerous penetrations of technical systems. These penetrations must meet appropriate fire tightness and insulation criteria depending on the fire resistance of the partitions they are located in.
System line penetrations are divided according to the type of technical system into:
- electrical system penetrations;
- system pipe penetrations;
- ventilation duct penetrations; and
- combined penetrations, i.e. different systems in one penetration.
Selection of an appropriate protection of a system line penetration through a fire zone boundary depends on many factors, including the system type and dimensions, and the partition type. Therefore, we select the most optimal solution from a wide range of products available in the market.
The scope of our activities concerning protection of system line penetrations includes:
Making electrical system penetrations in walls and ceilings:
- using the PROMAT system;
- using the HILTI system;
- using the ALFASEAL system;
- using the K-FLEX system; and
- using the WÜRTH system.
- using the PROMAT system;
- using the HILTI system;
- using the ALFASEAL system;
- using the K-FLEX system; and
- using the WÜRTH system.
Making ventilation, smoke, and air-conditioning duct penetrations in walls and ceilings:
- using the PROMAT system and
- using the HILTI system.
Making combined systems, i.e. protecting all system lines in one penetration:
- using the PROMAT system;
- using the HILTI system;
- using the SVT BRANDSCHUTZ system; and
- using the WÜRTH system.
