NEXGEN Greenshield TPO Membrane is a high performance, heat weldable, sandwiched fleece backed thermoplastic polyolefin (TPO) sheet, manufactured & supplied in specific thickness, designed for waterproofing roofs of new and existing buildings.
Based on advanced polymer chemistry, the membrane has excellent chemical resistance, sustaining cycles of hot, cold, wet and dry environmental conditions, remaining flexible over years, maintaining its integrity and continuing to provide protection from water seepage.
High mechanical properties of the membrane ensure superior puncture resistance, breaking & tearing strength, while enabling excellent heat weld for fusion along the edges.
The membrane is designed for adhesion to screed, PCC, RCC, cementitious and other adhesives for easy application over flat roofs & parapet walls, creating a monolithic barrier system. Tiles, screed can be adhered over the membrane.
Features & Benefits
- Supplied in pre-manufactured standard thickness. No thickness variation unlike liquid applied systems.
- Outstanding puncture resistance, high breaking and tearing strength, with very high peel strength of seam joints and heat welds
- Chlorine free, plasticizer free, phthalate free. Environmentally friendly and safe for humans
- Exceptional resistance to moisture, bacteria, chemical, and acid
- / bases corrosion
- Resistance to root penetration, suitable for green roofs and below ground applications.
- Continuous serviceability from -30oC to 100oC – without cracking, tearing or brittleness failure
