  • WÜTOP Perfect is a highly water vapour permeable underlay with a special membrane. It is laid directly on the heat insulation or formwork of ventilated and unventilated pitched roofs, with two self-adhesive strips

  • Airtightness membrane: Suitable as an airtightness membrane in accordance with EN 12114 in conformity with 13859-1/-2. Used as an airtightness membrane with water vapour permeable insulation, e.g. soft wood fibre insulation board. The airtight membrane can be used to construct verification-free roof structures in accordance with DIN 4108-3. For roof structures that deviate from this standard, verification can be provided in accordance with DIN 4108-3, Annex D.

  • The special membrane with its increased grammage results in an increase in performance in outdoor exposure

  • When combined with a WÜTOP vapour retarder/barrier and EURASOL adhesive tapes, it can be used to create modern airtight structures

  • Suitable as temporary roofing with an outdoor exposure time of up to six weeks

  • Technology: 3-layer, polypropylene-based non-breathable membrane with special functional membrane

  • Reliability due to the PP top fleece, which reduces the risk of slipping and protects the inner membrane through its 3-ply structure
