Specify TemStock-FR when constructing wall systems, fixtures, cabinets or furniture for industrial or commercial applications where a Class 1 fire rating is desired. It is an excellent substrate for wood veneers, high and low pressure laminates, as well as vinyl overlays, and may be cut, machined or drilled without significant effect on its flame spread rating.

FSC Certification
Particleboard produced at Temple-Inland's Monroeville, Alabama, Hope, Arkansas, Thomson, Georgia, and Diboll, Texas, facilities that is certified to conform to the requirements of Forest Stewardship Council™ standards for Chain of Custody, Controlled Wood and Reclaimed Material manufacturing is available by special order.

Formaldehyde Emissions
Large chamber air sample testing of Temple-Inland TemStock products has been conducted per ASTM E1333-96 (2002) to verify their conformance to California Air Resources Board (CARB) Phase 2 formaldehyde emission standards as well as the requirements of ANSI A208.1 Table B and HUD DFR Part 3280.
Warning
This particleboard contains low fuming urea formaldehyde resin and may release formaldehyde vapors in low concentrations. Formaldehyde vapors can be potentially irritating to the eyes and upper respiratory system. Should irritation develop, consult your physician.
