Description

RPI plastic lumber is produced from high-density polyethylene (HDPE), colorants (pigments) and UV inhibitors.

RPI Plastic Lumber is:

  • Manufactured to exacting specifications and is resistant to corrosive substances, oil and fuels, insects, fungi, salt spray, and other environmental stresses.

  • RPI Plastic Lumber does not absorb moisture and will not rot or splinter.

Maintenance

To maintain the original finish, clean the lumber with soap and water. No sealing or painting is required; as a general rule, paint will not adhere to RPI lumber products.

Limitations

It is not recommended for use as a structural member. It is also recommended that an engineering study be performed prior to the use of RPI plastic lumber if the application involves any structural requirements.

When utilizing RPI plastic lumber for decking or flooring, careful attention must be paid to joist spacing. Supports should be placed 12 inches on center for 1x profiles. Profiles greater than 1x may be utilized at 16 inches on center. For heavy load bearing applications additional support may be considered.

Basic Uses

RPI plastic lumber can be used as replacements for wood lumber applications. For exterior applications where weathering resistance and low maintenance are required, RPI lumber should be your choice.

Used in both residential and commercial applications, RPI plastic lumber will exceed the performance of conventional lumber in the worst environmental conditions.

Flammability

The materials utilized in recycling plastic lumber are flammable but not combustible, HDPE is difficult to ignite and the flame will normally self extinguish.

Accepted extinguishing method: DRY CHEMICAL, CO2, WATER FOG/SPRAY, and FOAM. Emissions from combustion are carbon dioxide, carbon monoxide, H2O, nitrogen and organic vapors.
