The Isothermic Difference

At Isothermic, making sustainable choices goes beyond words. 

It is reflected in our materials, in our partnerships, and in the way we design the building envelope. Whenever possible, we prioritize recycled and recyclable components, local sourcing, and suppliers committed to ESG initiatives. This approach is reflected in a broad offering of aluminum, wood, and PVC windows, as well as in our façade solutions, all designed to contribute to more sustainable buildings. With 12 Passive House products in our portfolio—some certified under our name, others manufactured using certified systems—we reaffirm a simple conviction: building better also means reducing energy consumption, greenhouse gas emissions, and carbon footprint, both at the building scale and across our operations.

We continuously invest in research and development to advance the design, materials, and real-world performance of our products. This approach is supported by our internal laboratory certified by UL, as well as by external laboratories, technical partners, and equipment manufacturers across North America and, when relevant, internationally. It allows us to remain in constant evolution, drive continuous improvement, and develop new products capable of pushing beyond minimum requirements, increasing durability, and delivering performance that can be tangibly felt—both today and over the long term.
