Asfaltos Chova

Asfaltos Chova, known by its Chova brand, is a Valencian maker of waterproofing and thermal and acoustic insulation based in Tavernes de la Valldigna. It produces Politaber bituminous membranes, insulation panels, acoustic products and technical adhesives for building.

For roof waterproofing, the choice between an adhered, mechanically fixed or ballasted system depends on slope, substrate and whether the roof will be walked on or planted. Choosing the membrane without defining the complete system often causes problems at laps and junctions.

For a project, state the roof type, area, substrate and final use. Request the membrane data sheet, the recommended system, upstand details and information on trained installers, and confirm whether on-site technical support is available.
