    Advantages

    • Impressive longevity
      With our DELTA®-FOXX PLUS the focus is on longevity. The sheeting maintains performance over the course of years and protects reliably. This is confirmed by extreme quality and long-term testing and the corresponding ETA. Roofs have reliable protection with DELTA®-FOXX PLUS.
    • 30-year warranty promise
      We guarantee that our DELTA®-FOXX PLUS, expertly installed, will retain its function (resistance against water penetration: Class W1) for 30 years. If a problem arises regarding this during this time, we will not only replace the material, but also bear the cost of removal and installation. The procedure is simple: one call and we take care of it.

    • Highly flame-resistant
      DELTA®-FOXX (PLUS) satisfies the requirements of Euro fire class B-s1, d0. This means that the roofing membrane makes a key contribution to preventive fire protection. The spread of flames is rendered more difficult, and homes and their inhabitants are protected. 
    • Secure adhesion 
      The integrated self-adhesive edging enables direct gluing of the overlap and reliably prevents the penetration of cold air and moisture to the insulation. This enables more energy efficiency and living comfort. The self-adhesive edging also enables overlapping adhesion.
    • Reliable rain protection
      To ensure that rainwater rolls off more rapidly, DELTA®-FOXX PLUS features the lotus effect. In combination with the DELTA® system components, the sheeting enables the creation of a rain-proof sub-roof in accordance with ZVDH* regulations.
    • Excellent temperature and UV stability
      The sheeting is particularly temperature resistant up to +150°C and specially UV stabilised. It can be subjected to solar radiation for up to 24 weeks without any anticipated material damage. Benefit from this characteristic – even where the roofing process is delayed somewhat.

    Equipped with DELTA®-AMS and DELTA®-BiCo technologies.

    Application

    DELTA®-FOXX (PLUS) was specially developed to meet the high requirements of being laid on wooden sheathing. Laying directly onto thermal insulation or as lining is also possible without any problems. In addition, the membrane is also suitable for use as temporary roofing and as a base layer under metal roof coverings, fibre cement panels or slate.

    Rainproof sub-roof *

    DELTA®-FOXX (PLUS) enables the creation of a rain-proof sub-roof in combination with the DELTA® system components  (DELTA®-SCHAUM-BAND, DELTA®-FLEXX-BAND and DELTA®-THAN). The breathable solution with DELTA®-FOXX has already proved its worth in over 25 years of practical use, however, it deviates from the diffusion-restricting solution described in the ZVDH regulations. Reference is made to this in the offer.

    Base layer and dividing layer beneath slate or metal coverings
    In combination with the DELTA® system components DELTA®-FOXX PLUS can be used as a dividing layer and a base layer beneath metal roof coverings – also with low roof inclines from 3°. In combination with DELTA®-ENKA VENT it can also be used to create a structured dividing layer. Beneath slate the membrane offers a secure base layer, as the wooden sheathing can dry faster due to the low Sd value of 0.02 m. In addition, the practical roll dimensions means that DELTA®-FOXX PLUS offers significant laying advantages compared to classic bituminous base layers: wider, longer, faster! The sheeting can be laid from the ridge to the eaves.

    More information on laying can be found in our laying instructions for sarking, underlay and sheathing sheeting as well as in the laying instructions for dividing layers and base layers.

    * An “individual contractual agreement” is to be concluded between contractor and customer for the creation of a rain-proof sub-roof.
