The invisible and innovative half welt in the area of textile sun protection. Here, the flagless welt is friction-locked with the fabric and replaces the customary hemstitch seam into which the welt must be additionally inserted.

With traditionally sewn awnings, small leaks occur at the fold due to the perforation of the needle. This is completely different with the NonVi Ecog: here, the welt lies in the welt rail and possible leaks have no effect. The welt is bonded along the edge of the fabric. The friction-locked connection disappears completely in the welt groove of the fabric shaft and/or in the existing profile and ensures a seamless appearance without ply jumps.

The NonVi Ecog is made of soft PVC that can be coated according to customer requirements. It is available in various sizes and can be adapted to the respective profile.

The NonVi Ecog and the NonVi Ecos that we present on page 19 have identical properties. They only differ in terms of the processing.ᶢ und der NonVi Ecoˢ, den wir auf Seite 19 vorstellen, haben die gleichen Eigenschaften. Sie unterscheiden sich lediglich in der Verarbeitung.

  • By dispensing with the traditional fabric fold, the NonVi Ecog saves material.

  • The seamless transition into the profile creates an appealing appearance.

  • Even in transmitted light, there is no optical interference due to seams or double plies of material.

  • Significantly easier handling during assembly as well as time and space- saving installation.

  • The welt is bonded directly with the fabric edge to form a friction-locked unit with no further material used.
