Product information

Product name


Product description

The product consists of cross-laminated timber (CLT) panels complying with the definition of CLT presented in ANSI/APA PRG 320-2012. The product may be manufactured with Canadian species machine stress-rated (MSR) Grades E1, E2 and E3 and Canadian visual grade species V1 and V2 of the PRG-320 standard. The product is intended for use as panels in floor, roof and wall applications. The product is available in widths ranging from 305 mm to 3 048 mm (12 in. to 120 in.), in thicknesses of 87 mm to 315 mm (3.4 in. to 12.4 in.) and lengths up to 12 m (40 ft.).


The adhesive used in the finger-joints is Hexion Cascomel 4720/5025A (CCMC 13252-L). The laminations are face-glued using the Purbond HB E302 or E202 adhesive (CCMC 13586-L); the boards are not edge-glued.

  Technical information

This evaluation is based on demonstrated conformance with the following criteria:

Evaluation requirements
Criteria number Criteria name
ANSI/APA PRG 320-2012, Grade E1Standard for Performance-Rated Cross-Laminated Timber
ANSI/APA PRG 320-2012, Grade E2Standard for Performance-Rated Cross-Laminated Timber
ANSI/APA PRG 320-2012, Grade E3Standard for Performance-Rated Cross-Laminated Timber
ANSI/APA PRG 320-2012, Grade V1Standard for Performance-Rated Cross-Laminated Timber
ANSI/APA PRG 320-2012, Grade V2Standard for Performance-Rated Cross-Laminated Timber

For compliance to the published values within ANSI/APA PRG 320-2012, the manufacturer utilizes visual grade V2. This Listing is based on the qualification testing and ongoing APA certification to ANSI/APA PRG 320. The structural building design using these panels must be conducted by a professional structural engineer in accordance with Clause 8 of CSA O86-2014 and Part 4 of the National Building Code (NBC) of Canada 2015.

Note: This manufacturer produces other proprietary grades of CLT that are beyond the scope of the ANSI/APA PRG 320-2012 and do not form part of this Listing and, as such, will not bear the CCMC mark.
