Rhepanol® fk

Rhepanol fk is a high-performance PIB (polyisobutylene) single-ply waterproofing membrane designed for long-life flat-roof applications, including warm roofs and green-roof systems. Manufactured by FDT, the membrane is free from plasticisers, halogens, chlorine, and PVC, contributing to a stable formulation with low environmental impact. Rhepanol fk is covered by an Environmental Product Declaration (EPD) in accordance with ISO 14025 and EN 15804, providing transparent life-cycle data for environmental assessment. Its long service life, resistance to UV ageing, and suitability for reuse or recycling at end of life support reduced whole-life impacts, while its compatibility with extensive green roofs and photovoltaic systems enables integration with broader sustainability strategies.
