PALIGHT®
3
Milling
PALIGHT can be milled by using standard milling machines of various types utilizing the following guidelines:
Relief angle: 5 to 10
Rake angle: -10 to 0
Cutting speed: 3,000 to 3,500 feet per minute
Cutting feed: 0.12 inches per revolution
Routing
PALIGHT material can be easily routed using multi-fluted carbide tools on standard woodworking
routers. Standard tools and machines can be utilized with no need to alter equipment. Adjust feed and
speed rates as needed to achieve the best edge finish on the PALIGHT parts.
Thermal Expansion / Contraction
As with most plastics, PALIGHT foamed PVC will expand and contract with an increase or reduction in temperature. This material
property is known as linear thermal expansion and contraction.
Since PALIGHT can be used in a wide variety of indoor and outdoor applications, linear thermal expansion and contraction may need
to be considered during the fabrication and installation of the material. It is important to take in to account the temperature at which
the PALIGHT material was fabricated as well as the temperature of the installation.
PALIGHT should not be used in applications or climatic conditions that exceed 140° F (ambient or surface temperature), at which
temperature the PALIGHT will soften and permanently deform. Dark colors are generally not recommended for outdoor use, as they
absorb heat and can easily exceed the maximum allowable temperature of 140° F.

Screwing and Nailing
Any type of screw or nail can be used to fasten PALIGHT material. Power nailers and screw driving equipment are suggested. Inserting
the screw or nail in an elongated slot or an oversized hole is recommended so that the material can expand or contract if fluctuations
in temperature occur. For best results, use oversized washers or grommets in combination with screws.
Installation
PALIGHT is manufactured as an extruded foam PVC product with a directional grain running the entire length of the sheet. This
manufacturing process gives PALIGHT greater flexural strength in the direction of the extrusion. The grain of the PALIGHT should
always be installed perpendicular to the fastening point.
