How to Improve Your TPO Roofing Installation

two-stage TPO adhesiveThermoplastic polyolefin, commonly referred to as TPO, is a material commonly used in commercial roofing applications consisting of a single ply membrane. TPO roofing provides many benefits to commercial buildings with easy installation and reflective properties that provide energy savings. TPO roofing is typically a bright white color that is resistant to damage from ultraviolet (UV) rays, chemical exposure, and ozone.

TPO and PVC Installation with Two-Stage Adhesives 

TPO and PVC roofing membranes are typically applied with industrial adhesives and mechanical fasteners to create a weather barrier and insulate commercial facilities. One popular method of TPO and PVC installation is by utilizing metal plates or pucks that are pretreated with a two or B stage adhesive. By utilizing a two-stage TPO adhesive, the metal plates can be installed with the TPO and PVC membranes, and then bonded after installation through a heat induction process that is now a commonly accepted roofing method and one that continues to grow at an accelerated rate.

By permanently bonding TPO and PVC through induction bonding, fastener penetration is eliminated,which improves energy savings and provides added protection and integrity of the roofing membrane. A typical TPO and PVC single-ply membrane is manufactured in sheets that are either 10, 12 or 20 feet wide in rolls that are delivered ready for installation. When installed with roofing plates and pucks treated with UNICHEM’s two-stage adhesive, the membrane is then induction bonded. This creates superior reliability and is a proven method for installing single-ply membranes.

Manufacturers of TPO and PVC roofing pucks and metal plates apply the two-stage TPO and PVC  industrial adhesive at the time of manufacture on a coil coating line, which allows for heat bonding at a later time. This drastically improves installation time for roofers, ease of application mitigate installation mistakes, which provides a higher quality of product for commercial property owners.
