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, as with all SCL, is intended for dry serviceFootnote (1) applications only.
• The product is intended for use in construction as an alternative material to lumber. Proprietary design values presented for the product are to be used by professional engineers for design in accordance with CSA O86 for structural applications, such as beams, headers, joists, rafters and columns as intended by the product manufacturer. The specific application must be qualified through testing and validated by the manufacturer. Applications such as I-joist flanges, studs and metal-plated truss chords are beyond the scope of this evaluation.
1. Manufacturer’s pre-engineered tables

There are no pre-engineered tables currently published in the product literature at this time. The spans for the product, when used as floor joists, rafters and beams, may conform to the spans for Select Structural Grade for the Douglas fir–larch group in Tables 9.23.4.2.A. to 9.23.4.2.I. of the NBC 2015 (for the same member sizes), except where a floor is required to support a concentrated load or a specified unfactored live load in excess of 1.9 kN/m2, and in lieu of engineering design. Maximum deflections must conform to Subsection 9.4.3., Deflections, of Division B of the NBC 2015. Floor joists must be designed to meet the deflection and vibration set in the NBC for lumber.

2. Manufacturer’s installation details

The product must be installed in accordance with the manufacturer’s installation guidelines engineered on a case-by-case basis.

3. Engineering requirements

For structural applications beyond the scope and limitations of Tables 9.23.4.2.A. to 9.23.4.2.I. of the NBC 2015 or when required by the authority having jurisdiction (AHJ), the drawings or related documents must bear the authorized seal of a professional engineer skilled in wood design and licensed to practice under the appropriate provincial or territorial legislation.

Installations beyond the scope/limitations of Sections i. and ii. of this evaluation imply, but are not limited to, the following:

• areas of high wind or high seismicity;
• design of supporting stud members/columns or the total beam/header load exceeds the NBC 2015 pre-engineered beam/lintel tables; and
• design of supporting foundation footings when the total load exceeds the NBC 2015 pre-engineered lumber floor/roof joist tables.

The specified strengths for the product must not exceed the values set forth in the table "Product specified strengths (MPa)" in this evaluation. See Figure 1 above for joist/beam veneer orientation.

The ends of all the product members used as joists, rafters and beams must be restrained to prevent rollover. This is normally achieved by attaching a diaphragm sheathing to the top or to the compression edge, and to an end wall or shear transfer panel capable of transferring a minimum unfactored uniform load of 730 N/m or the required shear forces due to wind or seismic conditions. Blocking or cross-bracing with equivalent strength may be used.

The compression edges of all the product members used as joists, rafters and beams must be laterally supported at least every 610 mm, except where design is done in accordance with CSA O86.

Nailing of the product perpendicular to glue lines must conform to Table 9.23.3.4., Nailing for Framing, of Division B of the NBC 2015. Nails must be installed parallel to the glue lines on the narrow face of the product that is at least 19 mm thick × 89 mm wide. The nails must be spaced at a minimum of 75 mm on centre (o.c.) for 63.5 mm common nails, and 100 mm o.c. for 76 mm and 83 mm common nails and No. 14 gauge staples. Common 89 mm nails installed parallel to the glue lines on the narrow face of the product that is at least 38 mm thick × 89 mm wide must be spaced at a minimum of 200 mm o.c.

4. Engineering support provided by manufacturer

The manufacturer may provide engineering services in conjunction with the manufacturer’s product specification and offers the following support contact number for their Canadian operations: 1-866-859-6757.

• This product must be identified with the phrase “CCMC 13485-R” along the side of the product. This CCMC number is only valid when it appears in conjunction with the certification mark of PFS Corporation.

Appendix A

The design values obtained from testing to ASTM D 5456, “Evaluation of Structural Composite Lumber Products,” as specified in CSA O86, are summarized below.

Table 3. Additional test information for RedLam LVL
Property Test information
Bending Specimens were tested in edgewise and flatwise bending to establish the characteristic value. Data from quality control (QC) tests were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CSA O86 was used to determine the specified strength.
Shear Specimens were tested in shear to establish the characteristic value. Data from QC tests were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CSA O86 was used to determine the specified strength.
Compression parallel to grain Specimens were tested in compression parallel to the grain to establish the characteristic value. Data from QC tests were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CSA O86 was used to determine the specified strength.
Compression perpendicular to grain Specimens were tested in compression perpendicular to the grain to establish the characteristic value. The characteristic value was multiplied by 1.09 to establish the specified strength in accordance with CSA O86.
Tension parallel to grain Specimens were tested in tension to establish the characteristic value (adjusted to 20 ft. gauge length). Data from QC tests were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CSA O86 was used to determine the specified strength.
Nail withdrawal Nail withdrawal values were established following ASTM D 1761, "Mechanical Fasteners in Wood," for an 8d common nail having a 31.75 mm penetration. Specimens were tested and equivalent species capacity was determined in accordance with ASTM D 5456, A2.4.
Nail bearing Dowel bearing strength was determined as per ASTM D 5764, "Dowel-Bearing Strength of Wood and Wood-Based Products," using 10d common nails with a nominal diameter of 3.76 mm and a lead hole diameter of 2.77 mm. Specimens were tested and the mean bearing capacity was used to establish the equivalent species capacity as per ASTM D 5456, A2.5.
Bolt bearing> Bolt bearing capacity was determined as per ASTM D 5764 using 12.5-mm- and 19.0-mm-diameter bolts.
Creep and recovery Creep testing was conducted in accordance with the CCMC creep and recovery test. After conditioning of the specimens, the creep and recovery performance was considered favourable. Long-term creep testing was also conducted, which demonstrated equivalency to duration of load behaviour of lumber.
Adhesive The adhesive complies with CSA O112.6-M1977, "Phenol and Phenol-Resorcinol Resin Adhesives for Wood (High-Temperature Curing)" (see CCMC 13019-L). The heat durability of the adhesive was confirmed using ASTM D 7247-07ae1 according to ASTM D 5456-10a.
