TPO Waterproofing System
Thermoplastic polyolefin membrane, hot-air welded.
System overview
TPO (thermoplastic polyolefin) membranes use polyolefin base polymers and contain no migrating plasticisers. Sheets are joined by hot-air welding, producing seams with strength approaching that of the parent material — well suited to fast installation over large roof areas.
Main advantages
Hot-air welded
Continuous homogeneous seams, installed without solvents.
No plasticiser migration
Polyolefin base retains flexibility over time.
Reflective surface
Light finishes help reduce roof surface temperature.
Installation speed
Wide sheet formats cover large areas quickly.
Applications
- Large-area industrial roofs
- Logistics and distribution centres
- Commercial and retail buildings
- Projects requiring light, reflective surfaces
