Support Strip
Support Strip is a reinforced tape made of vulcanized ethylene-propylene rubber EPDM, which facilitates the welding of the tape Thermobond R with the membrane of the Prelasti through the use of welding machines in hot air such as Leister Varimat or similar. The support tape is superimposed on top of the tape Thermobond P, which must be welded to the membrane of the Prelasti, and holds the lower layers in place during welding. Folds in the place of welding are not allowed, because the pressure created by the machine does not change.
