About this Project
There are many ways to add more insulation to a roof from blown-in fibreglass/cellulose from the interior to a layer of exterior insulation to a mix of both. But not every solution is ideal for every project. Leadership at the Trinity Baptist Church in Calgary, Alberta, The Trinity Baptist Church in Calgary, Alberta, aimed to improve the energy efficiency of their building to reduce operational costs and create a more comfortable environment during mass gatherings.
The church has a beautifully crafted cathedral ceiling with cedar plank roofing and the church did not want to loose the finish. That’s when they reach out to us to see if a comprehensive exterior retrofit would be a time and cost-effective solution to modernizing their roof assembly.
With the shingles on the church needing replacement in the near future, it was perfect timing for us to explore how adding exterior insulation can transform how the space feels without changing it’s iconic look.

The Solution
Working with our partnered engineer, Concept Plus Architecture and Engineering, we recommended a One-Sided OSB Panel featuring 7/16” OSB and 8” of Type II EPS insulation. This not only added an impressive R-40 for the roofing assembly but also preserved the cathedral ceiling finish, as per the church’s preference. Using SIS Roofing Panels ensured a speedy installation, mirroring traditional methods but with enhanced efficiency.
The Traditional Way
1. Strip shingles
2. First layer of insulation
3. Second layer of insulation, stagger the joints
4. New roof sheathing
5. Weather Resistive Barrier (WRB)
6. New roof shingles
The SIS Way
1. Strip shingles
2. SIS Roofing Panel
3. Weather Resistive Barrier (WRB)
4. New roof shingles
The Results
15-20% Faster To Install Compared To Traditional Methods
R-Value Was Upgraded From R-4 To R-44
The Streamlined Installation Helped Reduce Material Costs
After the SIS Roofing Panels were installed, Asonic Roofing stepped in to seamlessly install the peel-and-stick WRB and shingles directly into the fresh nailable surface provided by our panels. The process unfolded with ease, demonstrating how SIS Roofing Panels pose no complications compared to traditional methods of installing exterior roofing insulation. This successful collaboration not only elevated the energy efficiency of Trinity Baptist Church but also stands as a testament to our dedication to help clients find the best solution for their project.
