GALAXY FC are a range of APAO modified waterproofing bituminous membranes that combine excellent high temperature flow resistance, low temperature flexibility, strain resistance and dimensional stability with an outstanding endurance to UV ray ageing action.
The unique composition of the APAO modified compound employed by GALAXY FC is the issue of the studies conducted by General Membrane Research & Development Laboratories. This compound and the heavy-duty reinforcement employed by these membranes both contribute to ensure a unique versatility.
GALAXY FC membranes can be employed for waterproofing solutions that have to deal with the widest possible range of climatic conditions.
GALAXY FC membrane’s compound consist of a distilled modified bitumen mixture with a very high content of Amortphous Poly Alpha Olefins (APAO). These particular elasto-thermoplastic polymers are composing 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 cycle resistance, cold flexibility (-25°), typical of SBS modified high quality compounds and dimensional stability (140 C°) higher than SBS modified compounds.
The extraordinary resistance to thermal aging of this compound is reflected on incrased service of roofing. GALAXY FC membranes can be used in any climatic zone and mainly on high thermal insulation roofing. Excellent cold flexibility enables easy adaption of the membrane during the application which is an important feature in areas characterized by harsh climate.
This compound due to its specific formula, has also a remarkable behavior against UV rays ageing and provides excellent walkability during the covering, essential properties for a perfect finish of a fair-faced concrete where even the appearance must be impeccable. The compound, after thermal ageing cycle, doesn’t suffers any kind of decay in cold bending and dimensional stability.
The Reinforcement 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.
