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. 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.
