Our roof underlayments stem from innovations made by Innovatec owner Hans Klöber, who for many decades made a good name for himself in the premium segment of the roof construction industry with his former company, Klöber. What makes the patent-pending underlayments so special is the integration of a meltblown layer with different finishes depending on the area of application, enabling the underlayments to be custom-tailored to a variety of applications. In particular, the meltblown layer can be used to adjust water vapour permeability, water retention and dirt and dust filtration. Additionaly, the film can be replaced by a meltblown layer in certain applications. The underlayments are available commercially under the brand name JKE, Johannes Klöber Ennepetal. These brand name products are distributed exclusively via our partner ALUJET.
