Main models and classifications of Haobang waterproof TPO membrane

The main types of Haobang waterproof TPO membranes are as follows. If you want to learn more, you can check them carefully.

I. Model Classification

TPO waterproofing membranes are divided into three categories based on their structure:

1. Homogeneous Type (H): No reinforcement layer, typically 1.2mm, 1.5mm, 1.8mm, or 2.0mm in thickness.

2. Fiber-Backed Type (L): The lower surface is composited with a polyester non-woven fabric, typically 1.5mm or 1.8mm in thickness.

3. Fabric-Reinforced Type (P): Polyester fiber mesh is sandwiched between the membranes, with thicknesses ranging from 1.2mm to 2.0mm, enhancing tensile and puncture resistance.

II. Specifications

Standard Sizes: Common widths are 1.0m, 2.0m, and 3.05m; lengths are typically 20m and 30.5m, with other sizes available on request.

Thickness Tolerance: -5% to +10% is permitted (e.g., the minimum single value for a 1.5mm membrane is 1.35mm).

Example: `TPO Membrane P 1.50/20×2.00 GB27789-2011` indicates Category P, 1.5mm thickness, 20m length, and 2.0m width.

III. Application Compatibility

Category H: Flashing and detail joint treatment (excellent flexibility).

Category L: Fully bonded concrete base system.

Category P: Mechanically fixed roofs (wind-resistant), green roofs (root penetration resistance).

In summary, the selection of TPO membrane model should be determined based on the project scenario (e.g., rooftop/underground), construction method (mechanically fixed/fully bonded), and performance requirements (tensile strength/root resistance).
