The COLUMBA range of bituminous waterproofing membranes is characterized by good anti-ageing properties and resistance to UV ray ageing action. These membranes are particularly indicated for use in warm climates.
COLUMBA membranes employ a compound consisting in distilled bitumen modified with elasto-plastomeric polymers (APP). its quality is highlighted by two indicators: flexibility at low temperatures (-5° C) and high temperature flow resistance (110° C). These parameters positively affect and contribute to increase the service life of the roofing system.
The good flow resistance at high temperatures of these membranes makes them ideally suited for application in warm climates and for use on thermally-insulated roofs.
The compound employed by COLUMBA membranes is unaffected by UV ray ageing action and affords excellent walkability during application.
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.
