The Marwin Company is a manufacturer of quality Pocket Door Frames. Available in both Built Up and Knock Down types.

Plastpro PF Frames are full-length composite exterior door frames built to create a long lasting, rot-free entryway for your home. Together with Plastpro fiberglass doors, PF Frames create a weatherproof entry system to protect against the elements.

PF Frames are constructed with full-length PVC composite material. Our composite frames will never absorb moisture, rot, splinter, or rust like wood and metal doors. In other words: PF Frames are built to last.

Our innovative PF Frames are machined like wood, look and feel like wood, and can be painted or stained just like wood frames. The noticeable difference comes down to the strength and durability.
