PVC (Polyvinyl Chloride)
PVC (Polyvinyl Chloride), the predecessor to TPO, is another type of single-ply roofing system offered and has several great performance advantages.
Performance advantages include:
- Due to its durable composition, this material is highly resistant to punctures and tears normally experienced by most commercial roofing membranes.
- Unique resistance to fire that, when exposed, virtually extinguishes itself. Therefore considered one of the most fire resistance commercial roofing membranes offered.
- This material can easily accommodate a wide range of temperature changes with little deterioration.
- Perfect for industrial applications, this material is extremely resistant to industrial pollution and toxic chemical exposure.
- This material is heat welded during installation. This creates a molecular bond between sheets that provides waterproofing, durability, and longevity advantages.
- This material can also be coated or mixed with additives in order to comply with specific needs for individual roofing systems.
- The use of chlorine in the composition of this material extends its lifespan, decreasing the need for early roofing membrane replacement.
Other important facts about PVC include:
- It can be recycled repeatedly after initial use, it uses a low amount of non-renewable resources to create and requires the least amount of energy to produce out of any other roofing material on the market.
