Carlisle Companies Incorporated announced that construction has begun on Carlisle Construction Materials’ (CCM) sixth TPO manufacturing line, which will produce the commercial roofing industry’s first 16-foot-wide TPO membranes. Located in Carlisle, PA, the new line will add to CCM’s production capacity with the widest TPO sheets on the market. Consistent with Carlisle’s Vision 2025 strategy to invest in high-returning businesses, the new TPO line will support organic growth initiatives and also create jobs for the city of Carlisle and surrounding communities. The new line will begin production in early 2022. The widest width TPO membrane in the market now is available in a 12-foot sheet and was introduced by Carlisle in 2001. Wider TPO membranes have been an ongoing customer request, particularly with the steady increase in adhered and induction welded assemblies. Contractors using CCM’s new 16-foot-wide TPO membranes can expect significant labor savings and improved installation quality, as there will be fewer rolls to handle, more than 25% fewer seams to weld, and less packaging waste to dispose of at the end of the project.
