The GEMINI range of bituminous waterproofing membranes employs a high percentage of polymers and strikes an excellent balance of flexibility at low temperatures, thread resistance and behavior against UV ray ageing.
GEMINI membranes employ a compound consisting in distilled bitumen modified with selected elasto-plastomeric polymers and atactic polypropylene (APP), its excellent quality is highlighted by two indicators: cold flexibility (-10° C) and flow resistance at high temperature (120° C).
These parameters positively affect resistance to thermal ageing by increasing the service life of the roofing. Membranes with high resistance to thermal ageing and very good flow resistance at high temperature are suitable for application in any climatic area, and are particularly indicated in regions with warm climates for use on thermally-insulated roofing systems. The very good flexibility at low temperatures enables an easy application of the membrane, an important feature in areas characterized by harsh climates.
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.
GEMINI peculiar properties allow these membrane to be applied fully exposed on any type of roof.
Rot-proof non-woven spun-bond or staple polyester fabric stabilized with fiberglass. These “composite” reinforcements combine the excellent mechanical properties of polyester reinforcements with the extraordinary thermo-dimensional stability typical of glass-fiber and guarantee high levels of performance to the membranes
Rot-proof stabilized fiberglass reinforcements offering excellent dimensional stability and avoid unsightly wrinkling of the membranes and shrinkage of the waterproofing surface.
