Description:

Simple-to-use, one-component PU foam with B2 flame resistance, meeting DIN 4102 standards. It stops burning immediately when fire is removed, ensuring reliable safety for sealing joints, insulation, and gap filling. Compatible with foam guns or straw applicators, it expands and cures rapidly with moisture, offering strong adhesion, thermal/acoustic insulation, and crack sealing. Ideal for construction applications like fixing, installation, and gas separation. Environmentally friendly, CFC-free, and designed for durable performance in fireproofing and smoke penetration prevention.

Features & Benefits:

Self-extinguishing – Complies with B1 fire resistance (EN 13501-1).
Superior insulation – Low thermal conductivity for energy efficiency.
Closed-cell structure – Water-resistant, stable, and rigid.
High expansion rate – Fills gaps effectively with minimal material use.
Excellent adhesion – Bonds strongly to most construction materials.
Sound dampening – Reduces noise transmission.
No shrinkage – Maintains long-term stability after curing.
Easy application – Works with standard foam guns or straw nozzles.

Application:

Fire-rated door and window installations.
Fire and smoke barriers in walls, floors, and ceilings.
Sealing penetrations (pipes, cables, ducts).
Roof and cavity insulation.
Cold storage and HVAC insulation.
Industrial and commercial fireproofing.
