Compact fire protection knowledge. The new fire protection guide

Nowadays, fire protection presentsmany planners and installation en-gineers of building equipment withalmost insurmountable obstacles.Installations run like networksthrough complex building struc-tures.

The art of the planner is to har-monise the various networks, suchas supply and disposal, heating,ventilation and air-conditioning,with the electrical installation. Thatin itself is difficult. In addition, thethought of building safety hasbeen at the forefront for severalyears now. The sensitivity towardsfire protection in buildings is grow-ing.

As soon as the first step towardsfire protection planning has beencompleted, the appropriate sys-tems and components are in-stalled. Here, too, installation engi-neers are confronted with require-ments which cannot be implement-ed without further work.

Use approved section insulationfor metal pipes

Section insulation should also beapplied to steel electrical installa-tion pipes

Mount pipe sleeves for com-bustible pipes on both sides of thewall

Combination insulation for variousstructures with labelling

PYROMIX® is a special mortar,free of mineral fibres, for the cre-ation of cable and combinationinsulation. Depending on theamount of water added, the fin-ished compound can be appliedto the openings by hand, withpumps or with presses. The highlevel of substrate adhesion makelining unnecessary for small in-sulation sizes. A porous consis-tency makes retroinstallationeasy.

System benefits• Combination of multiple installations possible• Many approved section insulations, even Armaflex or Foamglas• Free of mineral fibres• Hollow shaft conductors permitted• Good substrate adhesion• Can even be used with small component thicknesses• Required consistency can be achieved by adding water• Easy retroinstallation

Fix pipe sleeves for combustiblepipes with threaded rods on bothsides


Secure soft insulation in ceilingsagainst footfall

OBO PYROPLATE® Fibre is amineral fibre or soft insulation.The core of the system is themineral fibre plate coated with amoisture-resistant ablation coat-ing. When there is a fire, the fireprotection coating forms an insu-lating carbon foam. Together withthe mineral fibre plates, this pro-vides effective prevention of thespread of fire and smoke. Ac-cording to the construction ap-proval, in addition to the cables,pipes made of steel, copper orvarious plastics may also be runthrough the same insulation.Therefore, the OBO PYROPLATE®Fibre is combination insulationfor various structures. For pipeli-nes, additional fire protectionmeasures (section insulation andpipe sleeves) are required.

System benefits• Combination of multiple installations possible• Many approved section insulations• Low insulation thickness - "Plate to plate"• Pre-coated plate with final coating is visually tidy• Moisture-resistant coating• Easy retroinstallation

Clean the layer and attach the lin-ing aids, e.g. adhesive tape

Apply the foam from the rear tothe front, and remove residues asnecessary


Electrical installation pipes up toM40, filled with cables or empty

Combustible pipes up to Ø 50 mmcan be run through without addi-tional measures


The PYROSIT® NG fire protectionfoam can offer many benefits inapplication and handling. Its par-ticular recipe means that the two-component material can offervery homogeneous localisedfoam insulation. The chemical re-action is perfectly matched toany requirements. The good sub-strate adhesion prevents thefoam from running out of theopening. Work can easily be in-terrupted to carry out checks.After the reaction process hasbeen completed, PYROSIT® NGhas a soft consistency, meaningthat retroinstallations are veryeasy.In addition to the cables, pipesmade of steel, copper or variousplastics may also be run throughthe same insulation. OBOPYROSIT® NG is therefore combi-nation insulation for variousstructures.

System benefits• Simple working, even with brief interruptions• Good substrate adhesion• Foam volume per cartridge up to 2.1 litres• Soft consistency - easy retroinstallation• No surface coatings required• Dust and fibre-free installation• Combination of multiple installations possible• Many approved section insulations• Battery pressing gun for large-scale use

Invisible insulation in screed-flushunderfloor ducts

Application of the fire protectionfoam directly under the wall

Empty pipes with tension wirescan be foamed in for assignmentat a later date

OBO's PYROSIT® NG fire protec-tion foam is a quick and simpletype of cable insulation for use inunderfloor ducts. If, during anelectrical installation, underfloorducts pass below walls classifiedfor fire protection, then the ductsmust be closed against smokegas penetration and fire.With an open duct system, theduct lid is removed on both sidesof the wall and the foam insertedon both sides. PYROSIT® NG isthe ideal solution for use inscreed-covered underfloor ducts:mounting is carried out, startingfrom the underfloor boxes onboth sides of the wall. Plastic in-stallation pipes can also befoamed in for later retroinstalla-tions.

System benefits• Applications covered by surveyor's comments• Simple working, even with brief interruptions• Good substrate adhesion, even on metal ducts• Foam volume per cartridge up to 2.1 litres• Soft consistency - easy retroinstallation• Empty pipes may also be foamed in as a reserve opening• No surface coatings required• Dust and fibre-free installation

System description, cable routing duct, PYROBAG® cushion insulation

Cushions arranged in the duct Retaining profile to prevent slip-page in vertical arrangements

Discreet attachment of the identifi-cation plate

The PYROBAG® cable insulation,together with the OBO KBK cablefire protection cushion, is the ide-al solution for insulation in PVCand metal cable routing ducts. In-sulation with the cable fire pro-tection cushions, which can beturned into any shape, can bemounted in a manner which isvery easy, quick, clean and dust-free.As the cushions are only mount-ed within the ducts, the cable in-sulation cannot be seen from theoutside – this is the preconditionfor a perfect cable duct installa-tion, which is usually subjectedto particular optical require-ments. The cushions can be usedfor permanent or temporary insu-lations in walls and ceilings. Ad-ditional cables can be installedquickly, tidily and economicallyat a later date, as the cushionscan be used several times over.

System benefits• Ideal solution for insulation in plastic and metal cable routing ducts• Insulation in the interior of the duct invisible on the outside• No visual impairment of the duct installation• Simple, quick, tidy, dust-free mounting• No coating or fillers required• Retroinstallations possible at any time

The pipe sleeves, type TCX of thePYROCOMB® system, can beused as independent pipe sealingfor combustible pipes (e.g. sani-tary wastewater pipes). Mountingtakes place with metal anchorson each side of the wall. Ceilingpenetrations only have a tubeseal from the underside. Thread-ed rods are mounted using thepush-through method in dry par-tition walls.In case of fire, the fire protectionmaterial inserted within the sealfoams up after a few minutes un-der high pressure, closing thesoft plastic pipes. This safely pre-vents the spread of fire andsmoke, should a fire occur.The PYROCOMB® pipe sleevesmay only be used to insulateplastic pipes in the PYROMIX®and PYROPLATE® Fibre systems.

System benefits• Many approved pipe materials• Sloping penetration (up to 39°) possible• Noise insulation on pipes need not be removed• Slender pipe sleeve structure• The size of the pipe sleeve may be three levels greater than the di-

ameter of the run-through pipe• Versatile application in various systems

System description, PYROMIX® Screed small insulation

Mineral wool with melting point ≥1,000 °C to plug the opening

2 cm-deep closure of the surfaceson both sides with the DSX insula-tion layer creator

Labelling of the small insulation

The PYROMIX® Screed small in-sulation only consists of twocomponents: OBO's insulationcreating material, type DSX, andthe MIW mineral wool. The non-combustible mineral wool has amelting point ≥ 1,000 °C andserves as a basis for the cable in-sulation. When the opening hasbeen plugged, both sides of theopening are sealed with the DSXinsulation creator.If there is a fire, the filler foamsup, preventing penetration by fireand smoke. The foaming actionalso draws heat from the cables,thus considerably reducing thetransfer of heat via the coppercores.

System benefits• Very simple assembly• Only two components required• Low-cost, approved components• In cartridges or in a bucket• Components can be used in other systems• Fulfils the requirements of the MLAR regarding so-called aids

System description, individual cables according to MLAR with insulatinglayer forming agent

DSX insulation layer creator, suit-able for full-wall ring gap closure insolid walls and ceilings

With light-duty partitions, filling thedouble plates to both sides is suffi-cient

The OBO insulation layer cre-ation material, type DSX, can beused to fill drill holes for penetra-tions with a single cable or multi-ple cables of a small cross-sec-tion, routed next to each other,through walls and ceilings mark-ing the end of fire sections, in ac-cordance with the cable systemsdirective.The ring gap around the cablemust be completely closed withfire protection filler. If there is afire, the filler foams up, prevent-ing penetration by fire andsmoke. The foaming action alsodraws heat from the cables, thusconsiderably reducing the trans-fer of heat via the copper cores.

System benefits• Low-cost, approved material• Simple handling• In cartridges or in a bucket• Components for other systems
