ISOLFON -FF is made of flexible cross-linked polyethylene foam and is soundproof for impact noise, suitable for floating floors made of concrete.

It addresses impact noises in floating concrete slabs in common residential and office buildings. It has very good thermal insulation capability.

ISOLFON -FF is available in rolls with a thickness of 5mm & 10mm with vapor barrier coating (PE film 0.10 mm) and overlap on one edge of the roll to prevent fluid penetration during concrete pouring.

The material is flexible, does not oxidize, is not affected by fungi and bacteria, and has excellent compatibility with common building materials (cement, plaster, lime, sand).

Applications:

• Soundproofing in floors between levels (creation of suspended or floating floors).
• Soundproofing in pipelines placed under floors, preventing the transmission of sound through the floors.
• Suitable for floors with final surface laminate flooring, ceramic tiles, marble, carpet, etc.

Technical Specifications:

• Temperature application range: -40°C +90°C
• Thermal conductivity: 0.035-0.04 Kcal/mh°C
• Water absorption (EN12087:2002): 0.10% kg/m2
• Compressive strength (ISO844) 25% Compression >0.03 Mpa
• 50% Compression >0.07 Mpa
• 75% Compression >0.18 Mpa
