Attic Insulation
Cut Heating Costs by Up to 50% With Proper Attic Insulation
A properly insulated attic is one of the most powerful upgrades you can make to your home or cottage. In Ontario’s cold winters and hot summers, heat naturally rises and escapes through the attic. Without enough insulation and air sealing, your heating and cooling system works overtime, driving up energy bills and reducing indoor comfort.
At Soundseals Insulation, we provide professional attic insulation services in Parry Sound, Muskoka, Almaguin, Barrie and Central Ontario to help homeowners reduce energy loss, improve comfort, and protect their investment.
Why Attic Insulation Matters
Your attic acts like the thermal shield of your home. When it is properly sealed and insulated, it helps:
-
Keep heat inside during winter
-
Keep cool air inside during summer
-
Reduce drafts and cold spots
-
Lower heating and cooling costs
-
Improve indoor comfort year-round
Many homes in Ontario are under-insulated or have insulation that has shifted, settled, or degraded over time. This leads to heat loss, moisture problems, and rising utility bills.
Professional Installation Makes the Difference
Attic insulation must be installed correctly to perform properly. At Soundseals Insulation, our trained crews follow Ontario building codes and manufacturer specifications to ensure:
-
Proper insulation depth and coverage
-
Safe and effective vapour barrier installation
-
Long-term performance and durability
Improper DIY attic insulation can lead to moisture problems, mold, heat loss, and expensive repairs. Professional installation protects both your home and your investment.
Signs Your Attic Insulation May Need an Upgrade
Attic insulation plays a big role in keeping your home comfortable and energy-efficient. In homes and cottages across Parry Sound, Muskoka, and Central Ontario, old or insufficient insulation can lead to higher energy bills, uneven temperatures, and air quality issues. Here are the most common signs that your attic may need an upgrade:
High Heating or Cooling Costs
If your energy bills are rising without a change in usage, heat may be escaping through your attic in winter or entering in summer. Poor insulation is often the main cause.
Drafts or Cold Spots
Feeling uneven temperatures in different parts of your home can indicate gaps in attic insulation or settled material that no longer provides a proper thermal barrier.
Visible Damage or Settling
Insulation that has compressed, shifted, or looks sparse in areas may not be performing as it should. Over time, batts can flatten and blown-in insulation can settle.
Signs of Pests
Animals like squirrels, mice, or birds can damage insulation and leave droppings. This not only reduces insulation effectiveness but can also affect indoor air quality.
Ice Dams or Moisture Issues
In winter, ice dams forming on the roof or condensation in the attic are signs that heat is escaping through the attic. This can also lead to mold growth if not addressed.
Age of Insulation
If your attic insulation is 10–15 years old or more, it’s worth having it inspected. Older insulation may no longer meet current energy efficiency standards.

Spray Foam vs. Fiberglass Attic Insulation
For attics in homes and cottages across Parry Sound, Muskoka, and Central Ontario, spray foam insulation offers unique advantages over traditional fiberglass. When installed correctly, spray foam creates a continuous thermal “blanket” that seals and insulates in a single step. It covers the entire attic floor, including joists, plumbing, wiring, and other penetrations, providing complete coverage that fiberglass alone cannot achieve.
Spray foam delivers a higher R-value per inch than most other insulation products, helping keep homes warmer in winter and cooler in summer. For maximum performance, spray foam can be combined with blown-in cellulose or fiberglass insulation, creating both an air barrier and a vapor barrier to reduce heat loss caused by air movement.
While spray foam is a premium option, the long-term energy savings and improved comfort make it a cost-effective investment. Many homeowners see a return on their investment within just a few seasons due to reduced heating and cooling costs.
