Yes, finger-joint studs are code compliant in Canada when manufactured and used according to the right standards. Parallel Lumber Group produces finger-joint studs that meet all Canadian building code requirements for vertical framing applications. This article explains how and why they’re accepted under Canadian regulations, and what builders should look for on the job site.
What Makes Finger-Joint Studs Code Approved?
Finger-joint studs are made by joining short pieces of lumber with a structural adhesive to create longer, straighter, and more stable studs. In Canada, these studs must meet NLGA SPS 3 standards in order to be approved for structural use.
To meet SPS 3:
- Studs must be used only in vertical compression applications, like wall studs.
- Bending or tension loads must be short-term (like wind or seismic events).
- Wood must be kept in dry-service conditions—moisture content under 19%, and temperature below 50°C long term.
As long as these requirements are followed, SPS 3 finger-jointed studs can be used in place of solid-sawn studs of the same species, size, and grade.
What Do Canadian Building Codes Say?
Finger-joint studs are recognized by both the National Building Code of Canada (NBCC) and CSA O86 – Engineering Design in Wood.
Key code details:
- NBCC 2015 Section 9.23.10.4.(1): Finger-jointing is the only allowed splice method for wall studs.
- CSA O86 Clause 6.2.3.2.1: SPS 3 studs are permitted in structural design when used vertically and kept dry.
This means if your finger-joint studs meet SPS 3 and are properly marked, they are fully approved for use in Canadian framing projects, whether for residential or commercial construction.
How To Identify Code-Compliant Finger-Joint Studs
When you’re on site or reviewing lumber for your project, look for the following in the grade stamp:
- Species and grade (e.g. SPF No.2)
- SPS 3 – Vertical Stud Use Only marking
- HRA (Heat Resistant Adhesive) designation
- Certifying agency (e.g. CLSAB or ALSC)
These markings confirm the stud is compliant and safe to use in code-approved wall framing.
