As one of Ontario’s leading developers of affordable housing, Indwell’s Graham Cubitt is passionate about creating “a really amazing place to live” for people who have often had very poor housing experiences. Indwell’s vision is to provide community renewal for its tenants, neighbors, and the broader cities where it undertakes these much needed projects. Cubitt said, “Our interest also extends to energy efficiency. It’s important for our tenants, many of whom have experienced homelessness, mental illness, or other disabilities, to be able to afford their utilities. Because Parkdale Landing will deliver such high performance, our tenants will enjoy safe and stable housing with very low utility bills.”

It is important for Indwell that its choices of insulation, equipment, and other construction materials reduce environmental impact. “A deciding factor for us was that Insulthane Extreme provided a global warming potential many times less than alternative products we considered,” said Cubitt. “There really wasn’t a difference in the cost of the overall project to use this much superior product. It became a clear, values aligned choice for us as a non-profit organization committed to environmental stewardship, along with economic stewardship.”

“We’re proud that Solstice LBA is contributing to Indwell’s goal to provide sustainable and affordable housing,” said Laura Reinhard, vice president and general manager, Honeywell’s Foam and Industrial Products business. “It’s also exciting to see the ongoing success of Elastochem’s Insulthane Extreme. As this project demonstrates, architects and leading contractors, such as Great Northern, value its ultra-low global warming potential (GWP) and superior foam performance.”

Attractive, High Performance Design Reflects City’s Heritage

From the beginning, it was clear that close collaboration between Indwell, Invizij Architects, Schilthuis Construction, and others would be essential. This complex project included gutting, rebuilding, and renovating an approximately 60-year-old neglected, fire-damaged building that at one time was a tavern and rooming house.

Emma Cubitt, project architect at Invizij, explained the design inspiration, “The building is located quite close to steel mills and the industrial part of our city. We wanted to reflect some of that heritage in the design by using exterior cladding that kind of looks like shipping containers, and colorful patterns to give energy to the facade."

Closed-Cell Spray Foam—The Right Insulation Choice

Early in the design phase, Invizij explored different insulation options to achieve the high level of energy efficiency required for Passive House certification, including mineral wool, wood fiber, and various types of wall assemblies. “Because part of this building was a retrofit, we had to insulate on the outside of the brick that was already there,” Cubitt said. “Therefore, to simplify the overall construction, we decided to insulate the entire building from the outside. Spray foam was the best way to achieve the R-values* and the air tightness we require.” Fiberglass clips for the cladding were specified to reduce thermal bridging.

Rockford Boyer, technical manager, building enclosure, at Elastochem added, “Today’s architects want superior technology in their insulation. Traditionally, Passive House buildings have used basic insulation types such as mineral fiber and others. By applying Insulthane Extreme to the building’s exterior over the membrane, it is providing a high-performance building envelope with a very low GWP.” Boyer emphasized that like all insulations, spray foam must be installed correctly and therefore, Elastochem partners with experienced contractors such as Great Northern Insulation (GNI).

Demand for Insulthane Extreme with Solstice LBA Rises

At Parkdale Landing, GNI is spraying 23 sets of Insulthane Extreme. C.J. Vanderwoude, GNI’s corporate production, training, and development coordinator, said the installation is going very well, “Our crew really enjoys the product. The adhesion and foam consistency have been extraordinary. The crew is also excited about being able to control and spray the same pattern at all times, with consistent yields and densities.”

He said, “To have a system that is easy to use for our sprayers, especially during training, is very important at GNI. The Solstice LBA system is an asset to us and all other insulation companies.” Mike Benetti, Elastochem’s commercial sales manager, is pleased with the way architects and contractors are embracing the product, “Architects see the environmental benefits of Solstice LBA over traditional spray foam materials and we’re seeing a big uptake in both the commercial and residential segments.”

Benetti said, “Insulthane Extreme is an integral part of Elastochem’s future growth. Due to its outstanding performance, as well as the phaseout of HFC blowing agents, we see it becoming a larger and larger percentage of our sales.”

Parkdale Landing—Providing Hope and Dignity

Graham Cubitt explained that Parkdale Landing will not only provide high quality housing, it represents much more, “For us, the underlying values are hope, dignity, and love. When we extend that to our tenants, they thrive. When we extend that to our neighborhood, it thrives. When we can extend that to our environment, we know we are having a positive impact on every community we’re a part of and we’re really proud of that.”
