Heat-weldable seams
The thermoplastic membrane is designed for heat-welded overlaps to create continuous waterproofing joints between adjacent sheets.
TPO Waterproofing Membrane
Thermoplastic polyolefin waterproofing membrane for exposed single-ply roofing and building waterproofing systems.
TPO waterproofing membrane combines flexibility with thermoplastic weldability and is designed for exposed roof systems on steel and concrete buildings.
Product Overview
0103
TPO waterproofing membrane is a polymeric waterproofing sheet manufactured primarily from thermoplastic polyolefin through an extrusion process. The material combines elastomeric flexibility with thermoplastic processability and is designed for heat-welded waterproofing systems.
The membrane is primarily used in exposed single-ply roofing systems and other building waterproofing applications. Typical projects include modern steel-structure roofs and concrete roof systems where a flexible, weldable and weather-exposed membrane is required.

Key Features
Weather-exposed roofing
Designed for exposed single-ply roof systems subject to outdoor weather conditions.
Low-temperature flexibility
The supplied product specification states no cracking under low-temperature bending at −40°C.
Flexible membrane structure
The material combines flexibility with thermoplastic processability to accommodate movement within roofing and waterproofing systems.
Plasticizer-free formulation
The TPO membrane is formulated without added plasticizers, avoiding performance changes associated with plasticizer migration.
