How to choose the specifications and models of TPO waterproof membrane for steel structure factory roof？

Self-adhesive TPO waterproofing membranes are selected for color steel plate roofs;

For color steel plate roofs and concrete roofs, composite non-woven fabric FS2 type TPO waterproofing membranes + 808 glue are selected;

Reinforced TPO waterproofing membranes are selected for rock wool insulation layers.

Weather resistance: TPO membranes can withstand extreme climatic conditions. Whether in hot summers or cold winters, they can maintain stable performance.

Low-temperature flexibility: In low-temperature environments, TPO can still remain soft, facilitating construction without brittle cracking.

Weldability: TPO membranes can be joined by methods such as thermal welding or mechanical fastening to ensure the continuity and integrity of the waterproof layer.

Physical reinforcement: Adding polyester fiber fabric between two layers of TPO materials can significantly improve its breaking strength, fatigue resistance, and puncture resistance, enhancing the durability of the waterproof layer.

During the construction process, the following points need to be noted:

Substrate preparation: Ensure that the substrate is dry, flat, and free of debris. This is the foundation for TPO membrane construction.

Welding techniques: Master the correct welding temperature and time to avoid over - welding or under - welding and ensure the firmness of the weld seam.

Detail treatment: Special treatment is required for details such as edges and corners to ensure the tightness of the waterproof layer.
