Inside and Out: Insulating Our Existing Masonry Buildings

In the Northeast, we have a large stock of uninsulated masonry buildings. Leaving these buildings as-is is not compatible with efforts to reduce carbon emissions and will not address climate shifts, the fabric of the community, or occupants' health. We explore insulating from the interior or exterior. The approach must be informed by feasibility, durability, toxicity of materials, installation cost, embodied carbon, emissions, and overall envelope performance, including freeze/thaw damage.
