ULTRAFLEX SA

SBS-modified bitumen self-adhesive polyester reinforced membrane for waterproofing without torching

Self-adhesive polyester reinforced SBS-modified bitumen membrane ULTRAFLEX SA is designed to complete secure application. It is used as an underlay on pitched roofs and as a vapor barrier. Could also be used for waterproofing of foundations and engineering structures. Thanks to the special adhesive bitumen compound, the material can be used on surfaces, where the standard torch-on application is forbidden (expanded / extruded polystyrene or wooden base).

Waterproofing material ULTRAFLEX SA has the following advantages:

  • Additional strength granted by polyester reinforcement;
  • Can be used on bases, where the standard torch-on application is forbidden (wood, OSB boards, XPS, etc.);
  • High speed of application;
  • Safe and cheap application – the membrane is applied without the use of gas and flame;
  • No need for any additional equipment and skills;
  • Cold application method prevents smoke, odors and noise;
  • Available with 2 types of the top surface: polymer film or fine-grained sand – for convenient installation depending on the area of application.
