Historic Gutters


A manufacturer of historically accurate replacement building products wanted to find an alternative to routing and milling laminated cellular PVC boards. The process was very costly and time consuming.


Chelsea utilized its tooling and material development technology to produce an extruded profile. Working with the customer to determine the products requirements, and how it would interface with components of the system, Chelsea Building Products was able to extrude this as a profile, eliminating the need for laminating boards, routing, milling and finishing.
