Choosing the Right Attic Insulation Material

When it comes to maintaining indoor comfort and reducing energy bills, choosing the right attic insulation material is essential. At RPM Home Services, we help homeowners across Ottawa, Cambridge, London, Dartmouth, Montreal, and Calgary make informed choices to keep their homes warm in winter, cool in summer, and energy-efficient year-round. If you’re considering an insulation upgrade or building a new home, understanding the best attic insulation types and how they can protect your investment is the first step.

Why Attic Insulation Matters for Local Homeowners

Attic insulation is your home’s primary barrier against energy loss. With the region’s cold winters and warm summers, a well-insulated attic delivers:

- Lower heating and cooling costs

- Enhanced indoor comfort all year long

- Improved air quality and moisture control

- Protection against ice dams and mold growth

Selecting the right material will depend on your local climate, existing structure, and specific comfort needs.

Comparing the Best Attic Insulation Types

There are several attic insulation options to consider, each with specific advantages. Local homeowners often ask us about the most effective solutions for their properties. Here’s a breakdown of the best attic insulation types we recommend:

Fiberglass Insulation 

Fiberglass insulation remains a popular choice due to its affordability and effectiveness. It is available in batts (rolls) or as loose-fill (blown-in), making it versatile for various attic layouts.

Benefits of Fiberglass Insulation:

- Cost-effective and widely available

- Excellent thermal performance

- Non-combustible and moisture resistant

- Easy installation for most attics

Spray Foam Insulation 

Spray foam insulation, both open-cell and closed-cell, excels at sealing air leaks and providing maximum energy savings. While it typically carries a higher upfront investment, the benefits can be substantial, especially in challenging climates.

Key Features of Spray Foam Insulation:

- Superior air sealing to prevent drafts

- Higher R-value per inch compared to traditional options

- Adds structural strength to the roof

- Moisture barrier reduces mold risks

Cellulose Insulation 

Cellulose is an eco-friendly attic insulation option made from recycled paper products. Blown-in cellulose is particularly suitable for older homes in Montreal, Ottawa, and beyond, where irregular attic shapes require flexibility.

Advantages include:

- High recycled content and low environmental impact

- Effective at filling tight corners and cavities

- Naturally resistant to fire and pests

Choosing Between Fiberglass vs Spray Foam Insulation

Homeowners often ask for a direct comparison: fiberglass vs spray foam. Here are some quick points to help you choose:

- Spray foam is ideal for maximum energy efficiency and moisture control, especially in harsh climates.

- Fiberglass is budget-friendly, effective, and suitable for most homes.

- Spray foam provides better air sealing but costs more upfront.

- Both options offer excellent durability, but installation should always be handled by professionals to ensure optimal results.

Local Climate Considerations: Ottawa, Cambridge, London, Dartmouth, Montreal, & Calgary

The Canadian climate brings unique challenges—from frigid winters in Ottawa and Montreal to humid summers in Dartmouth and Calgary’s temperature swings. Proper attic insulation isn’t just about comfort; it’s about protecting your home against:

- Ice dams that cause roof leaks and water damage

- Rapid temperature fluctuations that strain HVAC systems

- Mold growth due to insufficient moisture control
