Homogeneously weldable shaped element for interior corners



  • Simple implementation of vulnerable joints thanks to prefabrication
  • Reliable sealing of corners: Homogeneously heat-weldable with a solvent welding agent or hot air
  • Extremely high tear-resistance and very stable
  • Can be easily adapted for shorter base lengths, for example, using a knife or scissors
  • High degree of occupational safety: non-slip and abrasion-resistant surface

Areas of application

For reliable installation of joints at interior corners within the SOLITEX WELDANO roof lining system. The permeable shaped element, which is supplied pre-welded, can be welded to the SOLITEX WELDANO 3000 roof lining membrane in a homogeneous manner in terms of materials using the system solvent welding agent or hot air.

Installation instructions

General conditions

The membrane edges are to be welded using the WELDANO TURGA system solvent welding agent or a hot air gun. The welding area must be dry and free of frost, dust and grease. If dirt (e.g. oil) is stuck to the surface, moisten a cloth lightly with WELDANO TURGA system solvent welding agent and use it to clean off this dirt. Both sides of the membrane can be welded and are suitable as upper layers.

Welding with a solvent welding agent can be carried out at temperatures above 0 °C (32 °F). Please observe the hazard notices on the container.

If a hot air gun is being used, we recommend a temperature of around 220 to 280 °C (430 to 530 °F) depending on the ambient temperature and wind conditions. Test this setting by carrying out a test weld on a sample piece of membrane. A 40 mm (1.6") nozzle width has been found to be suitable in practice for welded joints between surface membranes. A 20 mm (.8") nozzle may be more suitable in certain cases for more intricate joints.

As an alternative to the use of the WELDANO ROFLEX, WELDANO INVEX or WELDANO INCAV system shaped elements, these elements can also be made by cutting appropriate shapes out of SOLITEX WELDANO 3000 membranes.


Suitable for installation on pressure-resistant subsurfaces, e.g. wooden decking, wood-based panels and wood fibre underlay panels. The subsurface must be dry, free of frost, clean and free of any sharp-edged or pointed objects.
