Material Characteristics & General Information

Q: What is it made of?
A: PERTH is crafted from recovered Maine hardwood fiber and rugged, UV-stabilized polypropylene. PERTH combines a unique polypropylene-based formula with a highly advanced manufacturing process to yield a superior material. PERTH is the only composite products you can buy made with polypropylene instead of polyethylene. Polypropylene (think of Tupperware® or those red gas cans) makes it stronger, stiffer, and lighter than other composites, so it can span longer distances and withstand higher temperatures with less expansion and contraction.

Q: Polypropylene - virgin or recycled plastic?
A: PERTH uses a mix of virgin and recycled plastic. Our primary source of recycled polypropylene is postal totes - those white plastic boxes that the mail comes in at the office. Polypropylene, being durable, is not used in many disposable items. Common applications are rope, car batteries, car bumpers, and red gas cans. Postal totes are our only source of clean, uncolored polypro (as you can imagine, we can't use off-color plastic in our premium products).

Q: What are some of the other uses for PERTH?
A: Lumber, products and railing, window profiles, wall studs, door frames, furniture, pallets, fencing, docks, siding, architectural profiles, louvers, automotive components.

Q: Will insects damage PERTH products?
A: No, it is too dense.
