As a Calgary homeowner, ensuring your home stays energy-efficient and comfortable during cold winters and warm summers is essential. When it comes to insulation, R-Value is one of the most important factors to consider. But what exactly is R-Value, and how does it impact your home’s insulation performance? In this guide, we’ll explain what R-Value means, why it matters for Calgary homes, and which R-Values are best suited for various parts of your home to ensure optimal comfort and efficiency.

R-Value depends on the material, thickness, and density of insulation. For example, spray
foam insulation has a higher R-Value per inch than blown-in fiberglass. Understanding how
R-Values work helps you make informed choices about the type and amount of insulation
needed to meet Calgary’s building standards and climate demands.

Calgary’s climate experiences extreme temperature fluctuations—from freezing winter lows to warm summer highs. Having the right R-Value insulation is crucial for:

• Reducing Heating and Cooling Costs: Insulation with the right attic insulation R-Value and wall insulation R-Value minimizes heat transfer, reducing strain on your HVAC system and lowering energy bills.
• Increasing Indoor Comfort: Proper insulation eliminates drafts and cold spots, ensuring every room is comfortable.
• Improving Environmental Sustainability: By reducing energy usage, you lower your carbon footprint, making your home more eco-friendly.

Different parts of your home need varying R-Values for optimal insulation. Here’s a breakdown of the recommended R-Values for your home:

• The attic is one of the most important areas to insulate. In Calgary, attics typically require an R-Value between 60 to 80 for maximum heat retention during winter. Blown-in fiberglass or spray foam insulation are excellent choices for attics, providing high R-Values and effectively filling gaps and hard-to-reach areas.

• For Calgary’s cold climate, exterior walls should ideally have an R-Value between 20 and 30. Fiberglass insulation or spray foam insulation work well for walls, providing insulation and air-sealing benefits. Upgrading to this wall insulation R-Value range in older Calgary homes can drastically improve energy efficiency and comfort.

• Basements and crawl spaces are often overlooked but are essential for whole-home insulation. Insulation with an R-Value between 15 and 25 helps keep floors warm and reduces moisture risks. Rigid foam panels are popular for basement walls due to their moisture resistance and effective thermal barrier.

• Cantilevers above unconditioned spaces, like basements or garages, benefit from insulation with an R-Value between 30 and 40. Adding high-R-Value insulation to these areas prevents cold floors and improves comfort in living areas. Spray foam insulation is effective here, as it provides a high R-value and seals air leaks.

While R-Value is key to insulation effectiveness, several other factors affect performance in Calgary’s variable climate:

• Moisture reduces insulation’s R-Value by compressing the material or causing mold growth, especially in materials like cellulose. In moisture-prone areas like basements, use
  moisture-resistant insulation like spray foam or fiberglass to maintain optimal performance.

• R-Value alone doesn’t account for air leaks. For best results, combine high R-Value insulation with air sealing around doors, windows, and other potential leak points.

Selecting insulation with the right R-Value for Calgary homes involves more than just choosing a material. Consider these tips:

• Evaluate Your Home’s Needs: Use an insulation audit to identify which areas need more insulation or have air leaks.
• Select Quality Materials: High-quality insulation materials provide higher R-Values and perform well in Calgary’s climate
