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
Thinking about upgrading your attic insulation? Here are answers to the most common questions homeowners ask about comfort, energy efficiency, and when it might be time for an update.
Still have questions about attic insulation in St. Albert?
St. Albert winters are long and cold. Quality attic insulation locks in heat, lowers energy bills, and helps prevent issues like roof frost and ice dams.
Many St. Albert homeowners see energy savings of about 15%–25% on heating costs after upgrading their attic insulation, particularly in older houses where the insulation is worn or insufficient.
Blown-in cellulose and fiberglass are both excellent choices for St. Albert homes. They provide strong protection against harsh winter temperatures and perform well in houses that already have some insulation installed.
If your home has drafts, uneven heating, or you notice thin spots or gaps in the attic insulation, it’s likely time for an upgrade. Properties built before 1990 are particularly important to inspect.
Most insulation lasts 20–30 years, but St. Albert’s cold, dry winters can cause it to deteriorate sooner if it wasn’t installed correctly. Regular inspections help spot issues before they become bigger problems.
It’s one of the most affordable and effective ways to keep your home cozy in winter and cool in summer. It also helps safeguard your roof from moisture, frost, and potential long-term damage.
In St. Albert, upgrading your attic insulation can typically pay for itself within 3–5 years through energy savings, especially in homes with older or insufficient insulation.
Blown-in insulation, typically made from fiberglass or cellulose, is ideal for covering large attic areas quickly and evenly. Spray foam creates an airtight barrier, making it better for sealing gaps, reducing drafts, and adding moisture resistance. Both are energy-efficient — the best option depends on your attic’s design and your budget.
Foam insulation, particularly spray foam, has a higher upfront cost but delivers outstanding air sealing and a high R-value. It’s a great choice if you need to address moisture issues, stop air leaks, or want long-lasting performance with minimal heat loss.
Yes — loose fill insulation is a popular choice for attics, particularly for boosting existing insulation. It easily fills uneven or hard-to-reach areas and is typically made from cellulose or fiberglass. It’s an effective way to improve energy efficiency without replacing all your insulation.
Spray foam insulation is ideal for attics with exposed joists and visible rooflines. It’s especially effective if you have moisture concerns, gaps, or hard-to-insulate areas where batts or blown-in material won’t work as well. A professional installer can evaluate your attic and recommend the most suitable solution.
Most homes benefit from insulating the attic floor, but if you use the attic for storage or as a living area, adding wall insulation will help maintain comfort. Insulating both can improve overall energy efficiency — especially in colder climates like St. Albert.
