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 batt insulation thickness must be between 89 mm and 190.5 mm.
The product must only be installed in structures where it is protected from precipitation and weathering (continuous dry service conditions). Use of the product in conditions of high indoor relative humidity (e.g., in enclosed swimming pools) is beyond the scope of the evaluation.
The product must not be used on the exterior side of exterior sheathing.
The product can be installed between wood-frame members in the following NBC 2015 and NBC 2020 Part 9 building assemblies: above-grade walls, above-grade floors, and attics and cathedral ceilings with NBC-required venting.
The product must not be used in locations where it will be exposed to compression, tensile and flexural loads.

Technical information

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

Evaluation requirements

CCMC-TG-072116.06-15	CCMC Technical Guide for hemp fibre thermal insulation
CCMC-TG-072116.06-20	CCMC Technical Guide for hemp fibre thermal insulation

Th e evaluation holder has submitted technical documentation for the CCMC’s evaluation. Testing was conducted at laboratories recognized by the CCMC. The corresponding technical evidence for this product is summarized below.

The range of the batt insulation thicknesses, from 88.9 mm to 190.5 mm, was identified by the manufacturer for qualification with the CCMC technical g uide. Tested specimens were cut from minimum, average and maximum thicknesses of the range to assess the physical performances. The following were the key performance areas for the evaluation.

Material characteristics

Thermal resistivity value was determined at design density, installation- related performance, materials properties under moisture conditions, potential corrosivity of metal-based components in contact with the product , fungus resistance, and (non-cellulosic) chemical separation for basic material qualification.

Thermal resistance under accelerated aging and cold temperatures

Thermal resistance performance after exposure to accelerated aging and cold temperatures was assessed to determine if the product can maintain its thermal resistance performance over time and th at there is no reduction in thermal resistance at cold temperatures.

Volatile organic compound (VOC) emissions

A human health risk assessment by a toxicologist was conducted to determine the maximum permissible VOC concentrations and the time-to-occupancy for installation when there may be occupants in the unaltered part of the residential building.

Fire safety

Flame propagation and smouldering resistance tests were conducted to determine whether the product behaves in a similar way to conventional thermal insulations and whether there are any atypical behaviours requiring further assessment.

Material characteristics

A series of tested specimens cut from 88.9-mm-, 140-mm- and 190.5-mm-thick batts were demonstrated to comply with the physical property requirements of Table 1.

Thermal resistivity under accelerated aging and cold temperatures

A series of tested specimens cut from 88.9-mm- and 190.5-mm-thick batts were exposed to: i) accelerated aging (wetting and drying cycles, high temperature, and high temperature and relative humidity), and ii) cold temperatures.

The results presented in Table 2 show that the product's thermal resistivity performance is maintained after exposure to accelerated aging, and increases when tested at cold mean temperatures. No abnormal behaviour was observed.

	at –7.5°C^{Table 2. footnote (1)}	m·K/W	≥ 18.5	23.51

Volatile organic compound (VOC) emissions

The VOC emissions were measured with an assumed room ventilation rate equivalent to 0.3 air changes per hour following the principles of CAN/ULC-S774 , " Standard Test Method for the Determination of Volatile Organic Compound Emissions from Polyurethane Foam." The procedure for measuring the material's typical VOC emissions profile elapsed for 30 days. Based on the emissions and room concentration calculations, the toxicological human health risk assessment recommends that the ventilation rate of 0.3 air changes per hour must be in effect for 72 hours before occupancy is permitted in the newly insulated suite, in accordance with Table 3. Reported results from emissions tests indicate that the product would be unlikely to cause major adverse health problems. While the testing and evaluation represent the current state of the art in toxicological evaluation, such tests and their results do not purport to be conclusive with respect to the impact on health.

Additional data

Data in this section does not form part of the CCMC's Code compliance opinion.

The product's thermal resistance at varying cold temperatures and thicknesses are outlined in Table 5. The thermal resistance is calculated using the overall average of the thermal resistivity results obtained for the 88. 9 -mm- and 190.5-mm-thick batts (shown in Table 1) for the given mean temperature of the insulation (see Notes 1 to 3 below).

Code Compliance via Alternative Solutions

Where a design differs from the acceptable solutions in Division B, then it should be treated as an "alternative solution." A proponent of an alternative solution must demonstrate that the alternative solution addresses the same issues as the applicable acceptable solutions in Division B and their attributed objectives and functional statements. However, because the objectives and functional statements are entirely qualitative, demonstrating compliance with them in isolation is not possible. Therefore, Clause 1.2.1.1.(1)(b) identifies the principle that Division B establishes the quantitative performance targets that alternative solutions must meet. In many cases, these targets are not defined very precisely by the acceptable solutions [...] Nevertheless, Clause 1.2.1.1.(1)(b) makes it clear that an effort must be made to demonstrate that an alternative solution will perform as well as a design that would satisfy the applicable acceptable solutions in Division B—not “well enough” but “as well as.”

National Building Code of Canada, Sentence A-1.2.1.1.(1)(b)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Alternative Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions

All CCMC evaluation reports are opinions of code compliance established in accordance with the National Building Code of Canada, Subsection 1.2.1. "Compliance with this Code," which requires compliance to be achieved by:

complying with the applicable acceptable solutions in Division B, or
using an alternative solution that will achieve at least the minimum level of performance required by Division B in the areas defined by the objective and functional statements attributed to the applicable acceptable solutions.

The CCMC assesses compliance with Canadian building, energy and safety codes, and is trusted by over 6,000 regulators across Canada.
