Fiberglass Batt Insulation
At Soundseals Insulation, we provide professional fiberglass batt insulation for homes and cottages across Parry Sound, Muskoka, and Central Ontario. Fiberglass batts are a trusted and affordable way to improve comfort, reduce energy loss, and control sound, making them an ideal choice for cost effective build for full-time residences and seasonal properties.
Whether you’re insulating a lakeside cottage, a new build, or upgrading an older home, fiberglass batts offer a reliable way to keep heat inside during cold Ontario winters and block excess heat during the summer months.
What Is Fiberglass Batt Insulation?
Fiberglass batts are thick insulation panels made from recycled glass that are made into fine glass fibres that are formed into flexible batts. These batts are designed to fit standard wall, floor, and ceiling cavities, making them perfect for homes, cottages, basements, and attics throughout Muskoka, Parry Sound, and Central Ontario.
Fiberglass insulation is:
-
Non-combustible and fire-resistant
-
Moisture-resistant
-
Mold-resistant
-
Excellent for sound control between rooms and floors
Our Soundseals technicians install fiberglass batts in:
-
Exterior and interior walls
-
Attics and ceilings
-
Basements and crawl spaces
-
Cottage & Home floors and roof cavities
Why Professional Installation Matters
Homes and cottages in Parry Sound and Muskoka face extreme temperature changes, moisture from lakes, and high humidity.
That’s why professional installation matters.
At Soundseals Insulation, we ensure fiberglass batts are installed:
-
With no gaps or compression
-
With proper vapor and air control
-
To Ontario building code
-
For maximum R-value and performance
When insulation, moisture control, and ventilation work together, your home stays warmer in winter, cooler in summer, and protected from condensation and mold.
Why Soundseals Uses AcoustaSeal & Advanced Vapour Barriers
At Soundseals Insulation, we go beyond standard insulation by using AcoustaSeal air-sealing products and high-performance membrane vapour barriers. These systems work together to create a tighter, healthier, and more energy-efficient building a completely sealed space. Something most insulation companies do not provide when installing Batts.
AcoustaSeal is a professional-grade acoustical and air-sealing sealant used to close gaps around framing, electrical boxes, joints, and wall penetrations. Even small cracks can allow warm air, moisture, and noise to move through your walls. By sealing these openings before insulation is installed, we eliminate air leakage that causes drafts, heat loss, and moisture problems.
Our membrane vapour barrier systems add another layer of protection. Unlike traditional plastic sheeting, membrane vapour barriers are designed to control moisture movement while allowing walls to dry naturally. This helps prevent condensation, mold growth, and long-term structural damage, especially important in Muskoka, Parry Sound, and Central Ontario, where homes and cottages face high humidity, freezing temperatures, and large seasonal swings.
By combining AcoustaSeal, membrane vapour barriers, and high-quality insulation, Soundseals creates a complete air-tight and moisture-controlled envelope around your home or cottage. The result is:
-
Fewer drafts
-
Lower heating and cooling bills
-
Better indoor air quality
-
Reduced mold and moisture risk
-
A quieter, more comfortable living space
This system-based approach is what sets Soundseals Insulation apart. We don’t just add insulation, we build a high-performance thermal and moisture barrier designed to protect your property for decades.
