High-performance SBS-modified bitumen torch-on membranes from Danosa, designed for durable flat and pitched roof waterproofing. The system typically combines Esterdan 30 P Elast as the underlay/base layer with Esterdan Plus 50/GP as the mineral-finished cap sheet for excellent long-term protection. Both products feature polyester reinforcement and elastomeric SBS bitumen for high flexibility, puncture resistance and reliability in demanding conditions. Ideal for professional torch-applied installations on new roofs and refurbishments. Esterdan Plus 50/GP (Mineral Cap Sheet) 5 kg/m² SBS elastomeric cap sheet with mineral granule finish for UV protection. Reinforced with non-woven polyester felt for high tensile strength and puncture resistance. Upper surface finished with mineral chippings; underside has quick-melt thermofusible film for easy torching. Suitable as the exposed top layer in multi-layer systems or single-layer applications. Excellent weather and UV resistance. Typical roll size: 1 m x 8 m. Esterdan 30 P Elast (Underlay / Base Sheet) 3 kg/m² SBS elastomeric underlay reinforced with non-woven polyester felt. Finished with thermofusible film on both sides for torch application. High flexibility, tear resistance and elongation for reliable performance. Ideal as the base/underlay layer in two-layer systems, or for tanking and buried structures. Typical roll size: 1 m x 12 m. Key System Benefits High-performance SBS modification – Superior elasticity, low-temperature flexibility and ageing resistance compared with standard bitumen. Excellent mechanical strength – High resistance to puncture, tearing and static/dynamic loading. Torch-applied convenience – Quick-melt film for efficient installation (including Safe2Torch detailing where appropriate). Durable waterproofing – Fully watertight with long-term stability. Versatile use – Suitable for flat roofs, pitched roofs under tiles, and selected tanking applications. Quality assured – Backed by Danosa technical data and relevant certifications (including BBA references on system use). Ideal for roofers and contractors seeking a reliable, professional-grade torch-on felt system. Esterdan Plus 50/GP provides the tough, UV-protected outer surface while Esterdan 30 P Elast delivers a strong, flexible base layer for complete waterproofing performance. Always install in accordance with Danosa guidelines and good roofing practice. Ensure correct substrate preparation, priming where required, proper overlaps, and full bonding. Use appropriate PPE and follow all safety procedures when torching. System guarantees depend on correct specification and installation.
