TPO Waterproofing Membrane System
Heat‑weldable single‑ply TPO sheets (1.2–1.5 mm)
Single‑Ply Roofing That Seals and Reflects Heat
Large roof areas face repeated hot/cold and wet/dry cycles while requiring dependable watertightness and reduced heat gain.
TPO membranes address this with a factory‑made single‑ply sheet, strong puncture/tear resistance, and heat‑welded seam joints that form a continuous waterproofing layer.
How TPO Roof Membranes Are Installed
TPO sheets are laid over screed/PCC/RCC and other cementitious surfaces; the membrane typically has a textured white top surface with a contrasting bottom layer.
Seams and overlaps are fused using heat welding to create continuous joints; the process requires skilled execution and supervision to achieve consistent weld quality.
Fleece‑backed variants enable improved integration with the roof build‑up where specified, while maintaining the same heat‑welded joint principle.
