Polymer bitumen membranes consisting of particular APAO compound which combines high temperature resistance and significant cold flexibility properties with resistance to stress and dimensional stability.
The PHOENIX SUPER membrane compound consists of a distilled modified bitumen mixture with a very high content of Amorphous Poly- Alpha-Olefins (APAO). These particular elasto-thermoplastic polymers consist of a terpolymer of Ethylene, Propylene and 1-Butene, which has a strong compatibility with bitumen; its peculiar qualities are highlighted by three indicators: thermal ageing resistance, cold flexibility (-35° C), better than SBS modified compounds, and flow resistance at the elevated temperature, higher (140° C) than SBS modified compounds. The extraordinary resistance to thermal ageing of this compound is reflected on increased service life of roofing. Phoenix Super membranes can be used in any climatic zone and mainly on high thermal insulation roofing. Excellent cold flexibility enables easy adaptation of the membrane during installation, which is an important feature in areas characterized by harsh climate. This compound, due to its specific formula, also has a remarkable behaviour against UV rays ageing and provides excellent walkability during application, essential properties on “exposed roofing”; where even the appearance must be impeccable. The compound, after thermal ageing behaviour, does not undergo any kind of decay in both cold flexibility and flow resistance at the elevated temperature.
The membrane is certificated by I.T.C. with D.V.T. 0004/2010 and by BBA with Agrément Certificate 99/3586.
The Reinforcement employed in The PHOENIX SUPER membranes consists in a heavy-duty rot-proof spunbond non-woven polyester fabric reinforced with glass fiber affording great elasticity, tensile strength and tear resistance. This is a “composite” reinforcement that combines the excellent mechanical properties of polyester reinforcements with the extraordinary thermo-dimensional stability typical of glass-fiber fabrics.
These combined properties avoid surface shrinkage and guarantee tensile strength, elongation and tear resistance allowing the membranes to absorb high levels of strain caused by structural movements of the underlying building and make it possible to employ mechanical fasteners to increase wind load resistance of the roofing system and withstand pedestrian traffic and static loads. Different reinforcements, as well as any other custom configuration of the product may be necessary to the Client, are available prior agreement with General Membrane.
PHOENIX SUPER can be supplied with either a sanded, talc, PP film or slate chip (mineral) top finish, while the bottom surface can be smooth or embossed and protected by a heat sensitive non-stick film PE/PP or sand. Since the PHOENIX SUPER compound is virtually unaffected by UV radiation, the membrane can be left without further protection. However the system is also available with the membrane’s upper surface coated with slate flakes that lower the membrane’s temperature when exposed to intense sunlight, which in turn all have the effect ofslowing down the aging process, increasing the life of the system.
