PHOENIX STAR are a range of bituminous waterproofing membranes featuring excellent low temperature flexibility and high temperature flow resistance. These membranes have been awarded Certifications both by the British Board of Agrément (B.B.A.) and the Italian Institute for Building Technologies (I.T.C.), the latter institution also issuing a technical evaluation document (D.V.T.).
The PHOENIX STAR membranes employ a compound consisting in distilled bitumen modified with selected elasto-plastomeric polymers and atactic polypropylene (APP); Their excellent quality is highlighted by two indicators: cold flexibility (-15° C) and high temperature flow resistance (130° C).
These parameters positively affect resistance to thermal ageing and increase the service life of the roofing system. Membranes with high resistance to thermal ageing and with excellent flow resistance at high temperatures are suitable for use in any climate, and particularly indicated in areas with hot climates and for use on thermally-insulated roofing systems.
Excellent flexibility at low temperatures enables an easy application of the membrane, an important feature in areas characterized by harsh climates or for application during the cold season. This compound, thanks to its special formula, features an excellent behavior against UV ray ageing and allows the membrane to be walked on during application.
PHOENIX STAR peculiar properties allow these membrane to be applied fully exposed on any type of roof.
The Reinforcement employed in PHOENIX STAR 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.
