Insulating a Custom Home in Thousand Islands
Hill Island, part of the picturesque Thousand Islands region, is known for its rugged landscapes, dramatic water views, and exposed weather conditions. Building a custom home in this environment requires more than just good design—it demands top-tier craftsmanship and materials that can stand up to extreme cold, summer humidity, and strong winds coming off the St. Lawrence River.
When the project manager overseeing a new custom build on the island began looking for a trusted insulation contractor, they needed a partner with deep experience in high-performance homes—a team that could deliver precision, efficiency, and long-lasting results. They turned to Panda Insulation.
The Challenge
Custom home projects are complex enough on their own. On Hill Island, challenges included:
- Exposure to the elements: Waterfront homes experience strong winds and moisture fluctuations, making insulation and air sealing critical.
- Structural complexity: Multiple wall systems, a flat roof, rim joists, and a garage ceiling—all requiring tailored insulation approaches.
- Tight construction timelines: The project manager needed insulation installed on schedule to keep the build moving without delays.
Every stage had to be carefully planned and executed to ensure the home met modern performance standards while remaining on track with the broader construction schedule.
The Panda Solution
Our team developed a full spray foam insulation plan that covered the entire building envelope:
🔹 Foundation Walls (R-12)
Closed-cell spray foam was applied 2” thick to the foundation walls. This added a continuous thermal barrier against cold ground temperatures while protecting against moisture intrusion.
🔹 Exterior Walls (R-24 & R-18)
The main walls of the home received 4” of spray foam for R-24 thermal resistance, while certain sections were insulated to R-18 at 3”. Spray foam provided both insulation and an air-tight seal, crucial in a windy, waterfront setting.
🔹 Rim Joists (R-24)
Often an overlooked source of heat loss, the rim joists were sealed and insulated with 4” of spray foam to eliminate drafts and prevent condensation buildup.
🔹 Garage Ceiling (R-36)
With living space above the garage, Panda installed 6” of closed-cell foam, delivering R-36 insulation to ensure comfort and energy savings in the rooms above.
🔹 Flat Roof (R-36)
The flat roof was insulated with 6” of spray foam, giving the home a high-performance roof assembly that helps regulate indoor temperatures and protect against air and moisture movement.
The Results
By insulating the home with closed-cell spray foam across the building envelope, Panda delivered:
- Superior energy efficiency – consistent thermal protection throughout the home.
- Structural durability – spray foam adds strength to walls and roofs while resisting moisture.
- Air-tight seal – reducing drafts, heat loss, and long-term operating costs.
- On-time delivery – the insulation was installed to specification and on schedule, allowing the build to stay on track.
The result? A high-performance custom home designed to withstand the unique environmental challenges of Hill Island, while offering the comfort, efficiency, and longevity the homeowners expect.
