PKjoists
PKjoists use proprietary grade flanges and come in several series with residential joist depths of 9-1/2” to 16” and commercial joists depths of 18” to 24”. With two 2x3 (PKI 20, 23) and three 2x4 (PKI 35Plus, 40, 50), the PKjoist can handle all your I-joist needs.
All PinkWood I-joists are shipped with a pink moisture sealer to protect the joists against moisture-related end-checking and moisture absorption. Below is the list of all PKjoists series - PKI 20, 23, 35Plus, 40, and 50 series.
SAFEjoists® - Your Fire Performance Solution
When you factory apply PinkWood’s WEBSHIELD® panels to our quality PKjoists, you get SAFEjoists. This product was designed to provide significant fire protection to unfinished basements and crawlspaces. PinkWood’s Patented Assembly has been evaluated and approved by the U.S. (IAPMO) and Canadian (CCMC) evaluation agencies and has demonstrated a time-to-failure in a fire equivalent to exposed 2 x 10 lumber joists. The assembly, available in depths up to 16”, meets the fire performance provisions of IRC Section R302.13 and Article 9.10.8.10.10. of the NBC, as well as CCMC’s directives published April 2020.
Proven Solution - SAFEjoist® system
At the end of April 2020, CCMC published new Evaluation Reports for those joist manufacturers, who sell joists in Canada. These Evaluation Reports now indicate whether a particular “protected joist” may be installed over unfinished basements.
PinkWood’s Evaluation Report confirms that the joists protected by the patented WEBSHIELD® system have passed the prescribed fire test and that they are approved to be installed over unfinished basements.
Most of the other producers do not have such a fire rated joist, in which case their Evaluation Report recommends that their standard joists installed over unfinished basements be drywalled.
