Firestop – system solutions

Firestop – system solutions in Central Switzerland – precise execution, on‑schedule handover.

Eurofugen – Firestop – system solutions in the Zürich area. We prepare the joint plan, verify substrate strength and movement, and select an approved system (neutral‑cure silicone, hybrid/MS polymer, PU) in strict accordance with manufacturer specs. Focus: EI60/EI90 – Klassifizierung. Planning priority: Fugenaufbau (Hinterfüllprofil, Primer, 2:1‑Geometrie). Standards: Approved systems per manufacturer classification; documentation per seal.

Quality & acceptance

  • Documented execution incl. photo record
  • Joint width/depth per plan (≈ 2:1)
  • Crisp edges without staining
  • UV/weather‑resistant sealants fit to exposure
  • Uniform, slightly concave finish profile

Planning & preparation

Primers are chosen per substrate absorption (e.g., clinker, fair‑faced concrete, fibre cement). Mock‑ups with cut‑and‑pull checks provide pre‑approval. Detailing at edges, reveals and penetrations is recorded in drawings. Joint layout based on panel sizes and anticipated movement; critical edge zones are eased. Create square, sound flanks, define depth and install the closed‑cell backer rod precisely. We verify weather and dew point; application only on dry, load‑bearing flanks.

Application & control

Apply sealant without bubbles, fill the joint evenly and tool to a slightly concave profile. Maintain movement capability; remove masking in due time and verify edge adhesion. Random cut‑and‑pull checks, width/depth measurements and visual inspection are recorded. Transitions at profile joints and material changes are re‑worked separately. Use UV‑stable systems and protect adjacent surfaces from contamination.

Joint routing aligns with the building’s movement grid.

Interfaces to adjacent trades are clarified to avoid follow‑on damage.

On natural stone we use low‑migration, stone‑safe systems.

Care guidance and maintenance intervals are included at handover.

Planning & preparation

Clean substrates, define edges and limit bond areas; primers & backer rod are matched to substrate and width. Mock‑ups and dew‑point checks secure approval. Interfaces are coordinated before start.

Application & control

Apply sealant bubble‑free, tool evenly and control dimensions. Check edge adhesion, remove masking in time and re‑work transitions neatly. Everything is recorded.
