The invisible and innovative welt seam in the area of textile sun protection. The welt is usually loosely inserted into the hemstitch seam. This is not the case with the NonVi Ecosˢ: the flagless half welt is sewn directly onto the edge of the fabric. The welt lies in the welt rail and possible leaks have no effect.

The now friction-locked connection disappears completely in the welt groove of the fabric shaft and/or in the existing profile and thus ensures a seamless appearance without ply jumps. The NonVi Ecos features a specially developed groove in which the thread lies in order to protect it against mechanical abrasion and other damage. This results in a lasting and strong connection between the welt and the fabric.

The NonVi Ecos consists of a PVC half welt with a groove. It is available in various sizes and can be adapted to the respective profile. By contrast, the NonVi Ecog is a bonded welt without a groove. Both products have identical properties and only differ in terms of the processing.

  • The continuous connection between the NonVi Ecos and the fabric ensures tension along the entire length of the fabric and thus prevents the formation of waves.

  • 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.
