Why Proper Attic Insulation Matters

Investing in quality attic insulation is one of the best decisions you can make for your home. Proper attic insulation doesn’t just improve comfort—it delivers lasting benefits that enhance your home’s efficiency, durability, and value.

Energy Efficiency

Keep your home warmer in winter and cooler in summer, reducing heating and cooling costs by up to 50%.

Improved Comfort

Minimize drafts and temperature fluctuations for a more comfortable living environment.

Longevity

High-quality attic insulation protects your roof, prevents ice damming, and extends the life of your shingles.

Eco-Friendly

We use Cellulose insulation, a sustainable material that’s fire-resistant, pest-resistant, and free from harmful chemicals.

Our Attic Insulation Services

Professional attic insulation services for homeowners in Edmonton, Red Deer, Calgary, and nearby communities.

New Attic Insulation Installation

Upgrade your home with high-quality cellulose or WallBAR insulation for better comfort and efficiency. We fully cover gaps, seal problem areas, and install insulation the right way so you get even temperatures, fewer drafts, and long-term energy savings.

Attic Insulation Upgrades

Older or thin attic insulation leads to cold rooms and high heating bills. We bring your attic up to modern energy standards by adding more insulation, fixing weak spots, and improving coverage. This helps reduce monthly energy costs and makes your home feel warmer and more consistent.

Attic Insulation Removal

Old or damaged insulation can cause drafts, odours, and poor indoor air quality. Our team safely removes outdated insulation and cleans the space so your attic is ready for a fresh, efficient upgrade. This gives you a cleaner, healthier attic and better performance once new insulation is installed.

Frost & Condensation Solutions

Attic frost and condensation often come from heat loss or poor ventilation. We find the cause and provide solutions like air sealing, insulation upgrades, and better airflow. Fixing these issues helps prevent moisture damage, mold growth, and winter “attic rain.”

Attic Insulation Options for Every Home and Budget

Every home is different. That’s why we offer several types of attic insulation, each with its own benefits for energy efficiency, cost savings, and long-term performance. Our experienced insulation installers can help you choose what’s best for your space.

Blown-In Insulation

Blown-in cellulose insulation is a popular option for upgrading attic spaces. Ideal for covering uneven areas and improving your home’s energy efficiency quickly.

Spray Foam Insulation

Great for sealing gaps and preventing air leaks. Spray foam insulation provides high R-value and moisture resistance.

Loose Fill Insulation

A cost-effective way to top up existing insulation. Especially useful in attics with difficult access or wall insulation needs.

Fiberglass Insulation

A long-lasting, affordable option that’s safe, fire-resistant, and great for both attics and walls.

Foam Insulation Panels

Used in specific areas like attic hatches or small wall sections to increase thermal resistance.

Just had Cosy top off my attic to R60 with Weathershield insulation. The guys were on time and did a fantastic job. Before starting the job they went through the process with me and then proceeded with laying out plastic to protect my floors and walls. Once they stretched out the hose to pump the insulation through and sprayed the WeatherShield in the attic. After removing the blower hose, plastic and tools, the vacuumed their work area. in addition to energy savings we will receive, we have noticed a quieter upstairs from the sound damping effect from the extra insulation. Highly recommend this company. Thank you, Clarence S

Had Cosy out to blow in insulation. Company was great to deal with from booking the appointment through completion of service. Workers were careful to put down plastic and clean up after themselves. Price was also very reasonable. Would highly recommend them

Mike and his team at Cosy Insulation truly impressed us with our attic insulation upgrade to an R-50 value using Weathershield™ loose-fill cellulose fiber insulation. Peter and Bruce, the installers, were not only friendly but also highly professional. They worked with remarkable efficiency and left the place spotless after the installation. Mike's pricing is very competitive, making Cosy Insulation an excellent choice for attic insulation upgrades. I highly recommend their services.
