WELDANO ROFLEX
Homogeneously weldable pipe grommet for roof pitches between 3° and 25° (0.6:12 - 5:12)
Advantages
- Keeps building components dry: windproof, rainproof and watertight
- Reliable seam sealing: homogeneously weldable with a solvent welding agent or hot air
- Easy to install: extremely high tear-resistance
- Practical handling: pipes can be pushed and pulled through the grommet – the joint remains sealed
- For pipes with diameters of 90 - 125 mm (3.5" - 5")
Areas of application
For reliable sealing of pipe feed-throughs within the SOLITEX WELDANO roofing underlay system. Suitable for roof pitches between 3° and 25° (0.6:12 - 5:12). The pre-fabricated grommet can be used to implement pipe feed-throughs in an easy, quick and permanently sealed manner.
The shaped element can be welded to the pro clima SOLITEX WELDANO 3000 roofing underlay membrane in a watertight manner using the WELDANO TURGA system solvent welding agent or hot air.
Installation instructions
General conditions
When carrying out adhesion using hot air or a solvent welding agent, press the membranes firmly using a plastic roller, taking care to ensure that there is sufficient resistance pressure.
Rainproof and waterproof adhesion can only be achieved on roofing underlay membranes that have been installed with no folds or creases.
Substrate
Before adhesion, SOLITEX WELDANO 3000 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 welded joints.
