hertaled is a unique alternative not only for lead, but for existing lead substitutes too. One of the most striking qualities of hertaled is its environmentally friendly composition. We have developed the material especially for that purpose.
A second striking asset is its flexibility. During the production process we integrate an aluminium expanded metal system in our EPDM membrane which results in a composite material of an EPDM slab with a pliable outer end, that is perfect for fitting to an inner cavity wall and it can be bent or formed into virtually any shape.
hertaled also features all of the – now familiar – qualities of our EPDM membrane. You can attach it to virtually any substrate, it has an exceptionally long life cycle, is very environmentally friendly, it is water and wind proof, stays flexible and does not leach out.
