Hi Robert. Thank you for the great review! We are happy we were able to help you out and meet your expectations. If you require anything else, let us know. The Cosy Crew. C Surfin2024-06-13Trustindex verifies that the original source of the review is Google. 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

Attic Insulation FAQs
Debating whether attic insulation is worth the investment? Our FAQ covers what you need to know about comfort, cost savings, and choosing the right time to upgrade.
Want to learn more about attic insulation in Calgary?
It combats winter heat loss, lowers monthly energy costs, and shields your home from roof frost and ice damming.
By updating attic insulation, Calgary residents often save between 15% and 25% on heating, particularly when replacing thin or worn insulation.
In Calgary, blown-in cellulose and fiberglass are proven solutions, keeping homes warmer and more efficient, especially when topping up existing insulation.
Cold spots, rising heating bills, or visible gaps in attic insulation usually mean it’s time to upgrade. Homes built before 1990 are especially worth checking.
Usually, attic insulation remains effective for 20–30 years. Yet Calgary’s extreme winters sometimes reduce that lifespan, which is why routine inspections are recommended.
Proper insulation provides year-round comfort, reduces utility bills, and safeguards roofing materials from frost, dampness, and wear over time.
Upgrading attic insulation often pays back its cost within 3–5 years through energy savings, especially in older Calgary properties.
Blown-in insulation quickly fills attic spaces, while spray foam offers airtight sealing and added moisture control. Both cut energy costs, but your decision depends on your goals and budget.
The upfront price is higher, but spray foam delivers lasting comfort, reduced heating and cooling costs, and reliable performance year after year.
It does. Loose-fill insulation is a practical choice to top up existing coverage, as it flows easily into tight or uneven spaces, improving overall efficiency.
Spray foam is recommended for attics with unusual layouts, gaps, or exposed joists. It seals tightly and resists moisture, but a professional evaluation will confirm if it’s the ideal match.
While attic floor insulation is standard, roof deck insulation is helpful if the attic is a living or storage space. In Calgary, using both can increase comfort and energy efficiency.
