Spray Foam vs Fiberglass: Ideal Insulation for Homes & Barns | Spray Foam Insulation in Calgary

Calgary, Canada - December 16, 2025 / Aztec Spray Foam Insulation Systems /

Calgary, AB - Aztec Spray Foam Insulation Systems provides reliable insulation solutions for Alberta homes, barns, and commercial buildings. Spray foam insulation in Calgary, AB, seals gaps, improves thermal performance, and supports healthier indoor air. Energy-efficient spray foam enhances comfort, reduces energy costs, and strengthens structures, helping property owners compare it effectively to fibreglass for lasting results in Alberta’s variable climate.

Alberta’s Climate and Insulation Needs

Alberta’s climate presents unique challenges for homes, barns, and commercial buildings. Harsh winters with temperatures well below freezing and hot summers place extra stress on heating and cooling systems.

Poorly insulated spaces can become uncomfortable quickly and force systems to work harder, increasing energy use and reducing comfort. Spray foam fills cracks and gaps, helping maintain a more stable indoor temperature throughout the year.

Heat loss occurs through walls, attics, and small gaps around doors and windows. Residential spray foam insulation forms a continuous layer that prevents heat escape, keeping spaces warmer in winter and cooler in summer. Unlike fibreglass, which can allow air leaks, spray foam lowers energy consumption and provides consistent comfort in Alberta’s changing climate.

Spray Foam Insulation Overview

Expansion and Sealing

Spray foam expands upon application, filling cracks and irregular spaces that fibreglass may miss. This creates a continuous thermal barrier, improving comfort and lowering energy costs.

Strength and Sound

Spray foam adds structural rigidity while dampening sound. It enhances the stability of walls, ceilings, and roofs and reduces noise inside buildings.

Moisture Control

Spray foam acts as a moisture barrier, reducing condensation and mould risk. Energy-efficient spray foam insulation protects structures and improves indoor air quality in Alberta’s changing climate.

Fibreglass Insulation Overview

How It Works

Fibreglass traps air between fibres to slow heat transfer. Proper installation is needed to prevent gaps, as settling or compression reduces effectiveness.

Moisture Limitations

Fibreglass can absorb moisture, lowering performance and increasing mould risk. Unlike residential spray foam insulation, it does not provide a complete moisture barrier.

Applications and Lifespan

Fibreglass is cost-effective for dry spaces but may require maintenance or replacement over time.

Direct Comparison of Spray Foam and Fibreglass

Spray foam insulation generally provides higher thermal performance because it expands and seals gaps, creating a continuous R-value throughout walls and ceilings. Fibreglass relies on proper installation and careful handling to prevent air leaks or settling. Spray foam also resists moisture, reduces noise, and adds structural strength, while fibreglass can absorb water and may need topping up over time.

Spray foam installation usually requires professional application, especially in irregular spaces, whereas fibreglass can sometimes be installed by homeowners in standard cavities. In terms of long-term performance, spray foam tends to last longer with minimal maintenance, whereas fibreglass may require replacement or adjustment.

Cost and Long-Term Considerations

Initial Costs

Spray foam insulation has a higher initial cost due to professional application and material quality. It provides a durable barrier that reduces energy loss over time. Fibreglass is cheaper upfront but may not cover gaps completely, which can lead to higher energy bills.

Maintenance and Longevity

Fibreglass can settle or shift over time. Spray foam resists settling, moisture, and mould, offering consistent performance for both residential and commercial properties.

Operational Costs

Energy-efficient spray foam insulation lowers heating and cooling expenses by reducing air leaks. Commercial spray foam insulation helps minimize HVAC workload in barns and commercial buildings, lowering operating costs.
