Thermoplastic Polyolefin (TPO) and Poly Vinyl Chloride (PVC)
With over two decades of experience working with these roof systems, CentiMark presently installs over 50 million square feet of thermoplastic roof systems each year.
Because of this expertise, CentiMark can provide clients with an array of thermoplastic roofing solutions. CentiMark will also assist customers in identifying State, Federal and Utility company rebates and incentives which may be available as a result of installing these energy efficient roof systems.
TPO and PVC roof systems
Thermoplastic Polyolefin (TPO) and Poly Vinyl Chloride (PVC) are thermoplastic roof systems that are both white and highly reflective roof membranes. These roofs provide excellent weathering characteristics and are highly resistant to ultraviolet light and most chemicals. The membranes have a reinforced scrim and are puncture and tear resistant. Thermoplastic roofs have outstanding seam strength due to the fact the sheets are welded together using hot air. These types of roof systems are lightweight and well suited for second generation (roof-over) applications.
There are three typical installation methods for TPO and PVC roof systems that provide lightweight and cost-effective solutions:
Mechanically Attached - The roof membrane is affixed to the structural deck with mechanical fasteners.
Fully Adhered - The membrane is bonded directly to the affixed insulation board or other roofing membrane substrate.
Point-affixed - Ideal for retrofit installation over metal applications, plates are installed at set intervals and the roof membrane is welded directly to the plates.
