If you’re thinking about reducing your energy bills and improving comfort, upgrading your attic insulation is one of the smartest and most affordable investments you can make.
Most Calgary homes — especially older ones — do not meet Alberta’s recommended R-value, causing major heat loss and increased utility bills.
This guide explains attic insulation costs in Calgary, what affects the price, and how to choose the right insulation for your home.

How Much Does Attic Insulation Cost in Calgary?
The cost depends on:
- Your attic size
- Existing insulation levels
- Material used (fiberglass or cellulose)
- How accessible your attic is
Most Calgary homeowners get one of these services:
✔ Attic Top-Up (most common & affordable)
Perfect if your home already has insulation but needs more to reach R-40 or R-60.
✔ Full Attic Insulation Upgrade
Recommended for homes with damaged, moldy, or old insulation.
✔ New Home Attic Insulation
For builders or newly constructed homes in Calgary.
Note: NS Insulation provides free inspections so you know exactly what you need — no overselling, no pressure.
What Affects the Cost of Attic Insulation in Calgary?
1. Attic Size
Larger attics require more insulation, increasing cost.
2. Current R-Value
If your attic is below R-20 (many Calgary homes are), you may need more material.
3. Material Choice
Fiberglass is the most popular and cost-effective.
Cellulose is great for soundproofing and eco-friendly homes.
4. Attic Condition
Existing mold, rodent debris, or moisture may require cleaning before installation.
5. Access Points
Small access hatches can increase installation time slightly.
Why Calgary Homeowners Choose Blown-In Insulation
Blown-in fiberglass insulation is the most common solution because it offers:
- Highest R-value
- Long lifespan
- Fire resistance
- Quick installation
- Uniform coverage
- Great value for the cost
For homeowners interested in eco-friendly options, cellulose insulation is also available.
How Attic Insulation Saves You Money
Upgrading your attic insulation can save Calgary homeowners 20–40% on energy bills.
Savings come from:
- Less heat escaping in winter
- Less heat entering in summer
- Reduced load on HVAC systems
- More stable indoor temperatures
- Less risk of ice dams and roofing damage
Most homeowners recover their insulation investment within 1–3 years through energy savings alone.
