TPO: Thermoplastic Polyolefin and PVC: Polyvinyl Chloride

 

 

What are TPO and PVC?

These roof systems are synthetic substances that are softened when heated, but harden upon cooling. These roof membranes are single-ply and can be installed using a variety of methods including mechanical attachment, point-affixed and fully adhered.

Benefits of TPO and PVC
Flexible protection.

TPO Roof Systems

TPO membranes are made with a co-polymerized rubber that allows them greater flexibility in cold climates. This membrane is best recognized for having the benefits of EPDM and PVC systems, at a more economical cost. TPO membranes are white and highly-reflective, making them an excellent choice for those looking to reduce energy costs. In addition to being ENERGY STAR rated, TPO’s recyclability makes it an environmentally conscious system. Additionally, TPO roofs are durable and resist dirt, bacteria and debris build-up making them highly resistant to tears, punctures and impact damage.


PVC Roof Systems

First installed in the early 1960’s, PVC was the industry’s answer to the oil crisis, as it was the first membrane to contain half of the fossil fuels normally used in system manufacturing. Engineers discovered that adding additional solid plasticizers to the PVC membrane allowed for additional weatherability and flexibility, where the membrane alone would be more susceptible to seasonal climate changes. To this day, PVC membranes remain incredibly versatile, chemical resistant and are highly recommended for roof-over projects. They are available in a variety of colors, thicknesses, widths, and reinforcements, making them an excellent option for almost any roofing project.

Along with the environmental benefit of using (fewer) fossil fuels in the manufacturing process, PVC is highly reflective/UV resistant, making the membrane an energy efficient option for warmer climates.

Pocatello, ID

A food processing facility was experiencing active roof leaks that could lead to a potential USDA food safety violation. The food processing facility had a plant shutdown coming up, so the roof needed to be replaced quickly and efficiently. CentiMark stepped in to replace the roof within the time schedule, completing over 100,000 square feet in less than 30 days. The result was a new 60-mil mechanically attached TPO roof, all installed during the plant shutdown.

Before: EPDM ballasted roof
After: 60-mil mechanically attached TPO, over ½” HD isocyanurate
Square Footage: Over 100,000
Warranty: CentiMark Single Source 20-year Warranty covering workmanship and material

 

 

Kent

New tenants were going to be moving into unoccupied spaces with multiple leaks at Kent Plaza. CentiMark was called in to upgrade the 30 year old roof system, fix the leaks, improve energy efficiency and increase tenant satisfaction. Not only did CentiMark mechanically attach a 1.2” polysio board along with 60 mil of TPO membrane via RhinoBond, but CentiMark also took extra time to blanket several hundred feet of power lines before beginning work. Extreme caution was taken to measure out and mark off the high voltage power supply so those areas were not penetrated with fasteners.

Before: Built-Up roof with gravel
After: Mechanically fastened TPO RhinoBond roof system
Square Footage: 20,000
Warranty: CentiMark Single Source 20-year warranty covering workmanship and material
