NovoProof® EPDM sheets are equipped with our patented ThermoFast® welding edges. It sets the stage for a thermal welding, which leads to durable connections of the sheets and membranes. The result: a safe waterproofing layer made out of one piece. Our customized collars, sleeves and preforms handle the most challenging details. NovoProof® molded parts are prefabricated and tested in the factory so that, when the ThermoFast® welding technique is professionally carried out, a perfectly waterproof flat roof is realized.
