Underlay membrane with 3D release film and self-adhesive strips


  • Highest possible durability and thermostability thanks to the TEEE membrane
  • Reliable drying out: highly permeable (sd value = 0.05 m ; g value = 0.25 MN·s/g ; 65 US perms)
  • Protects against corrosion and ensures improved noise insulation thanks to a 3D release film
  • Dry building components thanks to pore-free TEEE membrane that is resistant to driving rain
  • 3 months of outdoor exposure
  • Quick and reliable adhesion thanks to the integrated ‘connect’ self-adhesive zones along the membrane strips

Areas of Application

For use as roof lining or facade membranes for ventilated and non-ventilated structures in combination with all roof and facade materials such as titanium zinc, aluminium, stainless steel, galvanised steel, copper etc. Fibrous membranes offer greater protection for structures and are recommended by leading providers of metal roofs for this reason. The 8 mm (5/16") thick 3D separating layer made of fibrous PP protects the covering against waterlogging and dampens noise caused by rain or hail.

Installation instructions

General conditions

Install the SOLITEX UM membrane with the fibrous layer side facing outwards. The membrane is to be installed horizontally (parallel to the eave) in a taut manner as an underlay membrane on roof decking made of solid wood or wood-based panels.

Fasteners may not be applied in areas where water run-off is collected (e.g. in roof valleys).

Ridge ventilation should be provided in the case of non-insulated attics that have not been converted. In addition, permanent ventilation fittings should be provided in the unconverted attic.

Additional measures (e.g. covering with tarpaulins) should be taken during the construction phase in the case of buildings that are lived in or buildings that are to be given particular protection. Covering with tarpaulins should also be considered if construction work is to be interrupted for a longer period. The specifications in the regulations of the German Roofing Trade are to be taken into account when carrying out installation and adhesion.
