Impertek's roof line includes a complete range of solutions for waterproofing residential and industrial roofs. Drain connectors, collars, aerators, fittings and accessories (such as gravel-excluders, clamps and profiles) are made of materials compatible with bituminous membranes and synthetic felts such as PVC, TPO and EPDM-TPV. Each component is designed to ensure simple, safe and long-lasting laying: drain connectors attach the membranes to the downpipes, collars connect the sheets to the downpipes, and fittings facilitate installation in critical points such as corners and edges. The products can be applied by flame welding, hot air welding or incorporation, thus offering maximum operational versatility and perfect integration with any type of waterproofing
