Product Description

BILIN B2 Fire Retardant Polyurethane Foam for Window and Door 0

Description:

A versatile B2-grade polyurethane foam designed for sealing, fixing, and insulating tasks. It fills gaps seamlessly, prevents smoke and gas leakage, and reduces sound and heat transfer in buildings. With DIN 4102 flame-retardant certification, it self-extinguishes after fire removal and expands during curing to form tight seals. This foam is specifically engineered for fireproof building applications that demand reliable safety performance.

Features & Benefits:

Self-extinguishing to limit fire damage
B2 fire classification (DIN 4102-1) for strict fire safety compliance
Better insulation factor than conventional foams
Closed-cell structure: water-resistant, rigid, and stable
Excellent installation adaptability
User-friendly application process
High expansion ratio for efficient gap filling
Effective sound reduction and thermal insulation
Strong adhesion to common building materials
No shrinkage ensures durable sealing results

Application:

Fireproof door and window installation and sealing
Fire and smoke retardant sealing for wall-floor and wall-ceiling joints
Sealing of roof openings and construction gaps
Fire-rated filling and bonding projects including pipe penetrations and cold storage insulation
