Premierseal is a new high performance, single layer EPDM membrane roof cover from HH Robertson (UK) for flat and low pitched roofs.The system includes a wide range of options including looselaid, ballasted, mechanically anchored, fully and partially adhered and protected membrane.The membrane has a polyester backing which improves dimensional stability, gives more puncture and tear resistance and provides a substrate for a variety of fixing methods. A water based adhesive has been developed for use with the membrane.A feature of the system is that it contains no plasticiser or additives which can be washed out over a period of time, and the company says that it is not susceptible to the effects of solar radiation and ozone ageing.
