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 whether attic insulation is worth it? We’ve compiled answers to the most common questions homeowners ask about comfort, energy savings, and the best time to upgrade.
Still wondering about attic insulation in Red Deer?
Red Deer winters are long and harsh. Quality attic insulation helps retain heat, reduces energy costs, and prevents problems like ice dams and roof frost.
In Red Deer, many homeowners cut heating costs by 15%–25% after upgrading attic insulation, especially in older properties with thin or outdated materials.
For Red Deer homes, blown-in cellulose or fiberglass provide excellent defense against harsh winter temperatures. They’re especially effective in properties that already have some insulation installed, adding an extra layer of protection and efficiency.
If your home feels drafty, has uneven heating, or you notice thin insulation and gaps in the attic, it’s likely time for an upgrade. Properties built before 1990 are particularly important to inspect.
Most insulation typically lasts 20–30 years, but Red Deer’s cold, dry winters can cause it to deteriorate sooner if it wasn’t installed correctly. Routine inspections can help identify issues before they become costly.
One of the most budget-friendly ways to maintain a warm home in winter and a cool one in summer, attic insulation also safeguards your roof from moisture, frost, and long-term wear.
In Red Deer, improving your attic insulation can often pay for itself within 3–5 years through energy savings, particularly in homes with outdated or insufficient insulation.
Blown-in insulation, often made from fiberglass or cellulose, quickly and evenly covers large attic areas. Spray foam insulation forms an airtight seal, making it ideal for blocking drafts, sealing gaps, and providing extra moisture protection. Both options are energy-efficient — the best choice will depend on your attic’s design and your budget.
Foam insulation, especially spray foam, costs more up front but provides excellent air sealing and a high R-value. It’s ideal if you’re dealing with moisture problems, air leaks, or want long-term performance with minimal heat loss.
Yes — many homeowners use loose fill insulation to enhance existing attic insulation. Typically made from cellulose or fiberglass, it reaches into irregular spaces and is an efficient way to improve energy performance without doing a full replacement.
Spray foam insulation is effective for attics with exposed joists or visible rooflines. It’s especially useful when dealing with moisture problems, air gaps, or sections that are difficult to insulate using batts or blown-in materials. A professional can inspect your attic and recommend whether spray foam is the best choice for your situation.
Most homes gain from insulating the attic floor, but if the space is used for storage or as a living area, adding wall insulation can improve comfort. Insulating both areas can further enhance overall energy efficiency — especially in colder climates like Red Deer.
