Embodied Carbon Values in Common Insulation Materials
Embodied Carbon Values in Common Insulation Materials

Like many architects, we have begun to pay much closer attention to the embodied carbon associated with the materials we are specifying. All other things being equal, selecting a material with a lower global warming potential (GWP) is preferable. However, at this early stage, not many of us have a strong intuitive sense of how meaningful various GWP values might be – e.g. is 223 kgCO2e/m2 of insulation good or bad?
We performed a study to compare the embodied carbon values for nine commonly used types of insulation with the goal of presenting the results in a relatable way. The insulation products considered include two brands of XPS, two brands of next-gen XPS, Polyiso, Rockwool, Neopor GPS, fibreglass batts, and blown cellulose.
CAMH Research Centre
WINNER OF A 2020 CANADIAN ARCHITECT AWARD OF EXCELLENCE
“This is a big building that seems comfortable, with qualities of delicacy and softness. It brings something quiet, even if it’s busy from a programmatic point of view. It’s well-detailed in its sustainability aspects. The facade moves in and out, allowing the park to terrace through the building. It is also the most successful integration of mass timber that we saw among the entries. It’s the whole package, in a large, significant project.” – Stephan Chevalier, juror
The research centre will be Canada’s largest hybrid mass timber public building, and will showcase how the structural technology can be used in a curvilinear building.
