our houses are Made in Canada

Starting a construction products wish list for 🇨🇦gov (will probably be a thread): Get us a better pipeline for Knauf batt insulation (German) vs Owens Corning or Johnson-Manville. We can’t get Knauf Eco-Batt anymore.

But it would be great to have a list of made-in-canada building products...

We use a lot of James Hardie fire cement siding. CanCon options? klad.ca/portfolio/fi...

Another challenge is Soprema (Ohio) maker of blue skin membranes and insulation. Euro Alternatives we use: Siga and Proclima

Many Canadian window manufacturers use glazing units from Cardinal Glass (MN). Euro windows often use Saint Gobain. Lite-Zone is Canadian. Other IGU mfr?

Rheem heat pump hot water tanks are based in Georgia. Sanden and Daikin are Japanese, though the complex mech stuff (like cars etc) will be too tangled to look at its origins simplistically.

I am curious if you can buy any blue skin membrane and insulation from Europe that does the job, or if you can only buy a few select materials that have been tested to the Canadian (potentially harmonized with US) standard

We can use siga and proclima etc… just a matter of cost and availability

Soprema is a French company. Did you mean Bakor? Their Sopraseal Stick (and roofing membranes) are made in Québec.
