Frequently Asked Questions

Below are some commonly asked questions about marine grade polyolefin sheet and its performance in marine environments.

Marine grade polyolefin sheet is engineered to resist corrosion, saltwater exposure, and UV degradation.

Marine grade polyolefin sheet offers several advantages over traditional marine plywood. Unlike plywood, it will not absorb water, swell, or rot. It is also UV stabilized, so it resists fading and degradation. In terms of fabrication, polyolefin machines easily with standard woodworking tools, but it cannot be glued or painted like wood (mechanical fastening is required).

No. Unlike wood products, polyolefin sheet never needs painting, sealing, or refinishing.
