Types of White TPO Roofing Membrane

A TPO membrane is a single-ply roofing system that is widely used on commercial flat roofs because it is cost-effective, energy-efficient, and easy to install. TPO stands for thermoplastic polyolefin and is made of polypropylene and ethylene-propylene rubber, which are combined with other ingredients to form a white, durable membrane. A TPO roofing membrane is installed in large sheets that are then attached to the roof using mechanical fasteners, adhesive, or seams that are welded together using heat. The white color of the TPO membrane is important for reflecting sunlight and keeping the building cool.

There are three main types of TPO roofing systems, which are detailed below:

• Fully Adhered TPO Roofing Membrane:

  This type of TPO roofing system is installed by applying adhesive to the entire roof deck and then rolling out the TPO membrane and sticking it down. The glue holds the membrane tightly to the roof deck, which helps prevent wind from lifting it if there are strong storms. Because the membrane is glued down all over, it forms a very tight bond that helps keep water from leaking through seams. This system works well on roofs with lots of details and shapes where other installation methods might not stick as well. Fully adhered TPOs end up being durable and reliable since water has a hard time finding a path through the glued-down seams.

• Mechanically Attached TPO Roofing Membrane:

  In this installation method, the TPO membrane is secured to the roof deck using mechanical fasteners - usually screws with plastic discs called ''roofing washers.'' The screws are put through the membrane into the roof deck in rows, similar to how a parachute is attached. This allows the membrane to be held down very tightly so wind can't lift it in storms. Since the fasteners go through the membrane into the deck, there's an air space underneath. This air space helps reduce heat buildup on hot sunny days because the wind can travel through. Mechanically attached TPOs are often quicker and cheaper to install since no glue is needed. It's a good choice for roofs without many details or where the glue might not stick as well.

• TPO Roofing Membrane with Welded Seams:

  Another installation method uses a machine called a ''hot air welder.'' It heats up to around 700 degrees, and then the installer holds it against the seams where the TPO pieces need to be stuck together. The hot air makes the seam material inside get very hot so it melts into a solid bond. After cooling, the welded seams are as strong as the membrane itself. This creates a durable roof since water has a hard time getting through the seams. Welded seams are also very resistant to wind lifting. On windy nights, the seams hold tight, and the wind can't pull them apart. Some TPOs with welded seams have special texturing on the surface so the welder can control the heat better. Overall, welded seam TPOs end up being long-lasting and reliable.

Function and Feature of White TPO Roofing Membrane

The features of TPO roofing systems are advantageous for energy savings, cost-effectiveness, and sustainability. Here are some key features together with their functions:
