Product information

Product name

Nordic Lam™

Product description

The product is a glue-laminated timber construction made of black spruce in the tension and compression zones and/or Spruce-Pine-Fir (SPF) species in the core. All laminating boards (lamina) are surfaced to a thickness of 50 mm or less prior to lamination. The lamina is made of short-length pieces, typically 900 mm long with an occasional piece of not less than 685 mm long, and is end-jointed by means of a structural finger joint. Laminations of one or two grades are arranged within the depth of the member according to the desired layup pattern having one or three zones. Tables in the "Technical information" section of this Report outline the minimum layup requirements.

The lamina may also be made with multiple pieces of 38 mm × 38 mm lumber graded in accordance with standard grading rules and facebonded. The face bonding and end joints are bonded with a polyurethane adhesive (for end-joints: Ashland UX-100/WD3-A22, CCMC 13512-L; for edge and face laminations: Ashland WD3-A322/CX-47, CCMC 13591-L).

The Engineered Wood Association (APA) conducts regular audits of the manufacturing plant and the quality assurance program to CSA O177-06, “Qualification Code for Manufacturers of Structural Glued-Laminated Timber.” The engineering properties of the product are listed in the Tables in the "Technical information" section. The specified strengths for limit states design were based on the format conversion used in CSA O86 for conventional glulam. Additional engineering data is available from the manufacturer.

  Conditions and limitations

The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.

  • The product is intended for use where conventional glulam beams and columns are permitted for structural use by the NBC 2010.
  • The product is intended for use in dry service conditions only.Footnote (1)
  • The glulam beams covered within the scope of this Report must not exceed 2.0 m3 in volume and 600 mm in depth based on empirical data provided.
  • The product has met the adhesive testing requirements for Annexes A.2, “Small-scale flame test,” and A.4, “Elevated temperature performance,” of CSA O177. The intent of Annexes A.2 and A.4 is to provide information for decision-making by the designer or the authority having jurisdiction (AHJ) to determine whether the formulas in Appendix D-2.11, Glued-Laminated Timber Beams and Columns, of Division B of the NBC 2010, apply to these proprietary glulam columns/beams with an adhesive qualified under CSA O112.9 rather than a PRF complying to CSA O112.7, on which the formulas are based.
    • Annex A.3 provides for full-scale fire tests confirming compliance to Appendix D-2.11 of the NBC 2010, which have not been conducted.
  • The pre-engineering details outlined below have been provided to CCMC by the manufacturer to demonstrate compliance to Part 9, Housing and Small Buildings, of the NBC 2010 for acceptance by the local AHJ:
  1. Nordic Structures Pre-engineered TablesFootnote (2)

Additional test information

The product with built-up lamina that is made of short-length end-jointed and edge-bonded lumber laminations (i.e. less than 1830 mm long) is not covered in commodity-type glulam by CAN/CSA-O122-06, “Structural Glued-Laminated Timber.” In this case, the proprietary lami- nations are manufactured differently than described in CAN/CSA-O122, but are produced to match the same 20f and 24f conventional glulam stress grades to allow for direct substitution of the conventional laminations.

The equivalency being sought is with respect to producing conventional 20f and 24f stress grades. This was accomplished by establishing bending strength and stiffness that are equivalent to or better than conventional glulam lamination grades. The quality of manufacturing of new built-up short-length lamina in proprietary layup designs will be equivalent to glulam manufactured in accordance with CAN/CSA- O122. In addition, beams covered within the scope of this Report are limited to a maximum of 2.0 m3 in volume and 600 mm depth of beams.

Property Test information
Short-length elements The short-length lumber elements are typically 900 mm with an occasional piece of not less than 685 mm.  The laminating effect of joining 38 mm x 38 mm short lengths and face-bonding was demonstrated by testing a statistical sample of short-length end-joints, jointed short-length elements, and 38 mm x 140 mm lamina made of short-length elements.  In production, the jointed elements are proof-loaded at the full-length.
Tension Tension testing of 102 samples of various lamina grades was conducted to confirm the design tension values.
Modulus of elasticity Long span E was confirmed on statistical samples of all grades of lamina
Moment capacity

The moment capacity predictions were confirmed through testing of sixty (60) beams of 20f and 24f grades at 300-mm and 400-mm depths.  Fifteen (15) beams of 600-mm depth were also tested.

Shear capacity Thirty (30) short beams of 450-mm depth were tested to confirm the characteristic value.
Compression parallel to grain Thirty (30) short column tests were conducted to 89 mm x 89 mm and 140 mm x 140 mm columns to confirm the characteristic value.
Fasteners Fastener teste were not conducted to establish an "equivalent" species for fastener desingn.  SPF species are recommended for fastener design as a conservative approach.
Manufacturing quality assurance The manufacturing quality assurance program follows the principles of CSA O177 AND ANSI 190.1, which is verified by APA-EWS as part of the plant qualification.
Adhesives

The face and edge bonding and end joints are bonded with either a phenol-resorcinol adhesive or a polyurethane adhesive.  The products are currently qualified with the following adhesives:

  • for end joints: Ashland UX-100/WD3A22, CCMC 13512-L, and
  • for edge and face laminations: Ashland WD3-A322/CX-47, CMCC 13591-L
