Examples of technical application of the product:

Select the appropriate rope diameter for the given joint width from the application table. Place the rope in the expansion joint and press it with a blunt tool, e.g. a wooden slat

Properly sealed expansion joint with a single rope in the floor. The rope should be inside the floor. The surface of the rope should not protrude beyond the edges of the floor

Select the appropriate wire diameter for the given joint width from the application table. Place the rope on both sides in the expansion joint, pressing it with a blunt tool, e.g. a wooden slat

Properly sealed expansion with a double rope in the floor. The rope should be inside the floor. The surface of the ropes should not protrude beyond the edge of the floor

Technical description:

PIROSILICON 240 is a non-flammable and self-adhesive silicone mass intended for restoring the fire resistance of rigid walls with expansion joints. It is used to fill expansion joints together with PYROFOAM 240 or mineral wool in rigid walls made of concrete, aerated concrete, reinforced concrete, bricks or blocks with a density of not less than 600 kg/m3. The silicone mass can be applied directly to the PIROFOAM 240 G foam, PIROFOAM 240 W foam or mineral wool according to EN-14303 or EN-13162 used as a gap filling material.

Additional information:

PIROSILICON 240 is intended for fire-resistant seals:
• Horizontal expansion joints in building partitions constituting fire partitions with a possible shift of up to ± 7.5%
• Horizontal expansion joints in building partitions constituting fire partitions with a possible shift of up to ± 7.5%

Work with silicone should be carried out on a clean, degreased, dry surface at an ambient temperature above +5°C, with adequate ventilation.
