2. ‌Cost-Effective Quality Detection Methods‌ to choose TPO roof membrane supplier

For users who seek both affordability and basic quality assurance, the following methods provide intuitive and actionable insights:

‌Method 1: Visual and Tactile Inspection‌

1. ‌Thickness of the Exposed Layer‌: High-quality TPO membranes have an exposed white layer ≥0.4mm thick. Thicker layers enhance UV resistance and lifespan.

2. ‌Uniform Color and Texture‌: Check for colour consistency, absence of bubbles, cracks, or uneven pigmentation. Fold the membrane: premium TPO membrane shows no whitening, creases, or cracks at the fold.

3. Flexibility‌: Hold one end of the TPO roof sheet; the other end should drape softly. Rigid materials indicate poor flexibility and increased risk of installation issue.

   
   

‌Method 2: Buoyancy Test

Use a heat gun to weld two TPO roof sheets. High-quality membranes bond seamlessly without edge lifting or brittleness.
