When most people think about insulation, they picture staying warm during Calgary’s cold winters. But at Sorell Insulation, we know attic insulation is just as important during the heat waves of summer. If your home feels too hot upstairs or your AC can’t keep up, your attic may be the problem.

Your attic is the first line of defense against the scorching Alberta sun. Without proper insulation, your attic acts like a heat trap — and that heat radiates into your living space. This causes your air conditioner to run longer and harder, leading to higher energy bills and uneven home temperatures.

According to Natural Resources Canada, homes lose or gain up to 25% of energy through the roof. That means upgrading attic insulation is one of the most effective ways to improve year-round energy efficiency — especially in places like Calgary, where temperatures fluctuate dramatically.

At Sorell Insulation, we specialize in blown-in fiberglass insulation, and it’s a game-changer for attic performance:

1. 1. 1. Blocks Summer Heat from Creeping In

      Sunlight beating down on your roof can heat your attic to over 60°C. Blown-in fiberglass forms a dense, even thermal barrier that reduces heat transfer into your home — keeping it cooler, naturally.

2. 2. Cuts Down on Air Conditioning Costs

   When your attic is properly insulated to R60, your AC system doesn’t need to fight against rising attic heat. This can lower energy bills by 10–20% in many Calgary homes.

3. 3. Improves Indoor Comfort

   If your upstairs bedrooms or bonus rooms feel like saunas in July, poor insulation may be the reason. With proper attic insulation, you’ll notice cooler upstairs temperatures and fewer hot/cold spots throughout the house.

4. 4. Fast, Clean Installation

   Our team can top up or fully replace attic insulation in a single afternoon with minimal disruption. You don’t need to leave the house — we’ll be in and out before dinner.

5. 5. Durable, Safe, and Eco-Friendly

   Johns Manville fiberglass is non-combustible, resists mold and pests, and doesn’t settle over time — giving you peace of mind and long-term comfort.

You might think your home is “already insulated”, but most attics we inspect don’t meet modern R60 standards.

If your attic hasn’t been inspected in the last 5–10 years, you’re likely spending more on energy than you need to — especially during Calgary’s long summer days.

Insulating your attic in the summer doesn’t just help with cooling — it also protects your home from winter moisture issues. Proper insulation and ventilation work together to prevent:

A well-insulated attic with balanced airflow keeps your home dry and damage-free, no matter the season. See our Prevent Ice Damming This Winter With Proper Attic Insulation Article to dive deeper into this topic.

The connection between attic insulation and AC performance is simple:

• Without proper insulation, hot air from the attic enters your home faster than your AC can remove it.

• This leads to longer AC cycles, more wear and tear, and reduced lifespan of your HVAC system.

• Better insulation means your AC works less, lasts longer, and performs more efficiently.

Attic insulation is one of the fastest ROI upgrades you can make in a home. In Calgary, where both heating and cooling costs are a concern, that’s a smart investment year-round.

How do I know if my attic needs more insulation?

• If you experience high energy bills, temperature swings between floors, or overly warm rooms in summer, your attic may be under-insulated. A visual inspection (or a free visit from our team) will confirm.

What R-value should my attic have in Calgary?

• For Calgary’s climate, the minimum code is R60. Anything below R60 should be upgraded.

Can insulation really help my AC work better?

• Yes. Less heat entering your home = less cooling needed = lower energy costs and a more comfortable living space.
