TPO Membrane
Technical overview
Roll-supplied thermoplastic polyolefin membrane for single-ply roofing
Josoor supplies TPO waterproofing membrane in rolls. TPO means thermoplastic polyolefin: a factory-formed sheet used to create a single-ply waterproofing layer. Adjacent sheets are joined by heat welding rather than forming the membrane by mixing and curing a liquid coating.
Technical overview
- Material
- Thermoplastic polyolefin (TPO) sheet membrane
- Supply format
- Waterproofing membrane supplied in rolls
- Roof build-up
- Single-ply sheet waterproofing over the specified supporting roof assembly
- Seam formation
- Hot-air-welded overlaps between compatible TPO sheets
- Roof attachment

- Detailing
- Compatible TPO flashings and accessories at upstands, drains, curbs and penetrations
Typical applications by grade
- Flat and low-slope roofs on warehouses, factories and logistics buildings.
- Commercial and residential roof waterproofing within a specified single-ply roof assembly.
- Roof refurbishment over a prepared, compatible supporting build-up.
