Commercial roofs often encounter water build-up due to inadequate drainage. Membrane roofing solves this issue by effectively moving water off the roof. It also serves as an extra layer of protection against harmful elements that can cause rapid deterioration.
You have two great options when deciding to apply a single-ply membrane to your commercial roof: PVC and TPO. Read on to learn about the benefits of each choice.
PVC Single-Ply Membrane
Polyvinyl chloride is made from ethylene and chlorine and was first developed in Europe in the 60s due to the explosive growth of commercial establishments at the time. A PVC sheet has many notable components that contribute to its excellent performance, including plasticizers, stabilizers, UV deflectors, biocides and fiberglass reinforcement.
A PVC membrane, when installed by an expert roofing company, can perform well even after prolonged exposure to bad weather or extreme temperatures. A roofing company would normally recommend PVC membrane because it’s been tested to last longer than a TPO membrane.
TPO Single-Ply Membrane
The thermoplastic olefin or TPO membrane is a blend of polypropylene and ethylene propylene polymers with reinforced polyester. TPO membrane possesses flame retardants for fire resistance, UV absorbers, and colorants.
Unlike PVC membrane that has plasticizers, a TPO membrane has none. This means TPO is more resistant to shrinkage and tearing and shearing forces. TPO is also less expensive to install.
