Homogeneously weldable pipe grommet in the SOLITEX WELDANO roof lining system for roof pitches up to 50°



  • Homogeneously weldable as part of the SOLITEX WELDANO system with a solvent welding agent or hot air
  • For roof pitches between 5° and 50°
  • For sealing in the case of backed-up water, the flange can simply be extended using SOLITEX WELDANO-S
  • Extremely high tear-resistance and very stable
  • Windproof, rainproof and watertight


Homogeneously weldable pipe grommet for reliable installation of pipe feed-throughs within the SOLITEX WELDANO roof lining system. Suitable for roof pitches between 5° and 50°. The prefabricated grommet can be used to execute pipe feed-throughs in an easy, quick and permanently sealed manner.
To ensure a permanent seal even in the case of backed-up water, a strip of SOLITEX WELDANO-S must be welded to the resulting flange (see installation instructions).
The shaped element can be welded to the pro clima SOLITEX WELDANO roof lining membrane in a watertight manner using the WELDANO TURGA system solvent welding agent or hot air.

General conditions

When carrying out adhesion using hot air or a solvent welding agent, press the membranes firmly into place using a plastic roller, taking care to ensure that there is sufficient resistance pressure.
Rainproof and waterproof adhesion can only be achieved on roof lining membranes that have been installed with no folds or creases.


Before adhesion, SOLITEX WELDANO should be wiped clean with a cloth.
Adhesion to frozen surfaces is not possible. There must be no water-repellent substances (e.g. grease or silicone) on the membranes. Subsurfaces must be sufficiently dry and stable.

It is recommended that spot checks be performed to test the strength of the stuck joints.
