For Practitioners

Phius Certified Products are evaluated against criteria specific to passive building applications. This vetting process allows professionals to see how well products can meet the specific demands of a passive building. Head to the Phius Certified Product Database to find the fenestration products, ventilator units, or prefabricated panels that fit into your building designs.
