Product innovations to build homes in a better way.

  • Reduced heat and cooling loads mean smaller systems

  • Example: Lowering A/C needs can save approximately $300 per ½ ton of cooling

  • This number increases by approximately double for ASHP (air source heat pump) cooling loads. 


The table below outlines the National Building Code (NBC) current prescriptive requirements for achieving the minimum wall assembly insulation values across Canada. In Row 3, you’ll find the required RSI values, which represent the total effective insulation of the assembly.

With a standard 2x6 wall using R-19 fiberglass batt and 16” o/c stud spacing paired with BTRboard™, you not only meet the requirements in every climate zone but also eliminate the need for thicker insulation, double-wall construction, or complex designs. This provides significant cost savings in both design and implementation while ensuring top-tier insulation performance.

Moreover, if you desire even higher insulation values, you can easily upgrade the cavity insulation from R-19 to R-24 without introducing any additional design, engineering, or construction complexities. This flexibility allows builders to optimize performance and value without sacrificing simplicity and at a much lower cost than typical complex energy efficient walls.

Regarding the next chart below, as Canada moves towards Net Zero Ready homes, the challenge lies in finding cost-effective, buildable, and design-friendly solutions to meet these evolving standards without inflating construction costs. The table below outlines the National Building Code (NBC) performance metrics that guide us through a set of five tiers, gradually increasing the insulation and energy performance requirements for homes.

The two key metrics driving these changes are:

  1. Overall percentage of improvement: Starting from Tier 1 with no required improvement, advancing through 10% in Tier 2, 20% in Tier 3, 40% in Tier 4, and ultimately 70% improvement in Tier 5.

  2. Building enclosure performance: As we progress, the focus shifts towards improving the building envelope’s insulation values.

 

For example, in a city like Calgary or Regina, current requirements call for an RSI effective value of 2.97 (with HRV).

To meet Tier 5, we need to be 40% better than this benchmark. Fortunately, BTRboard™ offers a 38% improvement in insulation performance with a standard 2x6 wall and R-19 fiberglass batt. By simply upgrading to an R-24 fiberglass batt, using BTRboard™ with 24” o/c stud spacing, the RSI value jumps to 4.27, an improvement of 44% over today’s standards.

This approach is as simple and effective as it gets—no need for complex designs or added engineering. And with BTRboard’s commitment to continuous innovation in foam and assembly development, by the time we reach Tier 5, we expect to see even more advanced solutions that help builders achieve higher performance without extra costs or construction challenges.
