When CLT panels are installed under the IRC, an engineered design is required in accordance with IRC Section R301 .1.3.  \n3.0 DESCRIPTION  \n3.1 General:  \nThe Nordic X-Lam CLT panels described in this evaluation report comply with requirements noted in Section 2303.1.4 of the 2021, 2018, and 2015 IBC, for allowable stress design (ASD) in accordance with 2021 and 2018 IBC Section 2302 . 1(1) (2015, 2012, and 2009 IBC Section 2301 .2(1)) and load and resistance factor design (LRFD) in accordance with 2021 and 2018 IBC Section 2302. 1(2) (2015, 2012, and 2009 IBC Section 2301.2(2)), and consist of three to nine layers of softwood lumber boards (laminations), as shown in Table 1 , stacked with wood grain orientation alternating 90 degrees at each layer except that the outermost two layers or the two center layers are permitted to be parallel to each other. The Nordic X-Lam CLT panels  \nare manufactured by face-bonding each layer using a non-formaldehyde-based, exterior-type structural adhesive, and then are placed in a press to form a dimensionally stable structural element, or plank billet. The Nordic X-Lam CLT panels are available in plank billets with gross thickness of 3 inches (76 mm) to 12-3/8 inches (314 mm), nominal widths of 12 inches (305 mm) to 106-1/4 inches (2700 mm), and lengths up to 64 feet (19 .5 m) . Refer to Table 2 for the grade and layup designations of Nordic X-Lam CLT panels.  \nThe attributes of the CLT products have been verified as conforming to the provisions of (i) CALGreen Sections A4 .404.3 for efficient framing techniques; (ii) ICC 700-2020 Sections 608. 1(2), 11.608. 1(2) and [13.104.3.1](13.104.3.1)(4); (iii) 700-2015 and ICC 700-2012 Section 608. 1(2), 11.608. 1(2) and 12(A) .608. 1(b) for resourceefficient materials; and (iv) ICC 700-2008 Section 607 . 1(2) for resource-efficient materials. Note that decisionson compliance for those areas rest with the user of this report. The user is advised of the project-specific provisions that may be contingent upon meeting specific conditions, and the verification of those conditions is outside the scope of this report.
