DELTA-XX PLUS® LIGHT

A lightweight, durable, and affordable roofing membrane with a monolithic waterproofing layer that replaced the DELTA®-VENT N.


It is laid over insulation, providing reliable and long-lasting protection for roof slopes.

It ensures high hermeticity against water leaks and air blowing with excellent diffusion properties.

Warranty - 30 years.

Advantages

  • Longevity for cheap membranes with a guarantee of functionality preservation up to 30 years in case of professional installation.
  • If problems arise, the manufacturer compensates for the costs of material replacement and dismantling and installation.
  • Enhanced artificial aging tests are carried out, simulating an operational time of more than 30 years.
  • Integrated self-adhesive strips ensure reliable sealing at overlaps.
  • Reduction of heat loss by preventing the movement of cold air through insulation.
  • High flexibility and resistance to mechanical impacts.
  • The monolithic functional layer of TPU provides water and air impermeability while maintaining diffusion.
  • The matte surface reduces solar glare and increases installation comfort.
  • Improved hermeticity at reinforcement locations compared to polypropylene films.

Application

  • Suitable for laying over insulation in ventilated roofs and facades.
  • Used in constructions with cladding with closed gaps.
  • Not used on full coverage.
  • Adhesive tapes allow installation even in rain and at temperatures up to +5 °C.
