O'Fallon Roofing: Article About Tpo and Pvc Roofing
Pliable TPO (thermoplastic polyolefin) sheets have risen in popularity for use as industrial roofing membranes and have earned widespread industry approval by O'Fallon roofing companies due to its efficiency and its convenient setup. As the public need for heat-retardant and energy-efficient roofing products has grown in recent years, TPO roofing layers have stepped in to offer outstanding home protection against harmful ultra-violet rays, ozone gasses and chemical spills.
For the past few years, TPO has obviously been quite successful and has developed a sizable market share. However, other membrane materials still remain available from most building companies, and the majority of them have a relatively secure market interest.
PVC predates TPO as the very first malleable roofing sheet and has similar reflective properties. Despite the fact that TPO has been proven to have unequaled weather-resistance abilities, manufacturers continue to invest in PVC materials, and there are a few valid reasons for that. Mentioned below are a few of the differences between PVC and TPO roofing membranes, including which material is superior for certain types of roofing projects.
According to the results of various weathering and heat deterioration tests, when it comes to weather resistance, a TPO roofing system is superior to PVC. This fact may surprise many devoted PVC enthusiasts, who might not realize the extent of the improvements in TPO in the past few years.

In addition, TPO is highly resistant to mold and mildew growth while PVC tends to be more susceptible to such bacterial dangers.
However, although TPO boasts better weathering ability, mold resistance, and even slightly superior protection against rips and cracks than PVC, there are a couple situations where PVC roofing might be just as efficient or even preferable to TPO. For one thing, PVC is more resistant to caustic chemicals, and it doesn't soak up or get broken down by fats and oils. For this reason, PVC is often the preferable material to use when roofing restaurants or other structures that are fitted with rooftop oil drains.
In addition, PVC is a little more pliant than TPO, which some building contractors might prefer for certain types of roofing jobs. There was once speculation about weld quality variations between the materials, but it has since been determined that both products weld equally well. TPO needs hotter temperatures to become pliable, but after adaptations have been made, welding with TPO is just as simple as working with its PVC counterpart.
