EPDM waterproof membrane with TPE coating.
An EDPM waterproof membrane with a TPE (Thermoplastic Elastomer) welding strip along the edges. easy weld is suitable for forming ballasted, adhered or mechanically fixed, single ply roofs.
Joints are formed by hot-air welding using the TPE strip and the whole roof can be formed without the use of naked flame.
Performance:
Durability:
Properly installed, the system has a life of at least 35 years.
Design guidance:
– Substrates:
easy weld is suitable for use on concrete and timber-based substrates, as well as insulation boards laid over profiled metal sheet and existing bituminous roof coverings.
– Vapour control layers:
Depending on internal conditions a vapour control layer may be required: consult Hertalan (UK) for details.
– Separation/ Protection layers:
Where easy weld is mechanically fixed a separating layer of Hertalan easy tex may be required to prevent the membrane 'drumming' on the substrate or damaging EPS insulation board.
In inverted roof systems the membrane should be protected from the ballast by a layer of easy tex.
Where easy weld is to be installed over an existing bituminous waterproof covering with embedded chips consider using two layers of easy tex, or a thin mineral wool or EPS insulation board.
