TPO Thermoplastic Polyolefin Roofing Membrane

Product Overview

Thermoplastic Polyolefin (TPO) single-ply waterproofing roofing membrane. This advanced formulation combines ethylene-propylene rubber (for elasticity and durability) and polypropylene (for strength and weldability). It is modified with stabilizers, antioxidants, and UV absorbers to resist extreme weather, making it highly suitable for exposed roofing projects.

Key Benefits

• Cool Roof Efficiency: High solar reflectance index (SRI) which reflects solar heat, contributing to building energy savings.
• Extreme UV Resistance: Excellent resistance to ultraviolet light, ozone, and thermal aging.
• Eco-Friendly: Environmentally friendly: recyclable, plasticizer-free, chlorine-free, and non-hazardous.
• Welded Seam Integrity: Seams are hot-air welded to create a cohesive, leak-proof, monolithic joint stronger than the sheet itself.
• Flexibility: Remains flexible at low temperatures (-40 deg C) with high puncture resistance.

Installation Method

TPO can be installed using three main systems: 1) Mechanically Fastened: The membrane is secured to the deck using specialized plates and fasteners through the edge, and overlapping sheets are hot-air welded. 2) Fully Adhered: Substrate adhesive is applied to the deck and sheet backing, mated together, and rolled, followed by hot-air welding of seams. 3) Loose-Laid and Ballasted.

Packaging & Loading

Selling unit: Single roll. Approx. 8,000 to 10,000 square meters per 20ft container. Securely packed in original wrappers.

Storage & Shelf Life

Rolls must be stored horizontally on flat surfaces in clean, dry conditions. Keep away from fire and direct sunlight. Shelf life is 12 to 24 months.
