Performance
Building science, in the open.
Every number carries a label so you know exactly what it means: what has been physically certified, what is modeled, and what depends on your project. No blanket claims.

CalculatedFiberglass frame
Pultruded glass fiber moves with the glazing and barely conducts heat, so the frame edge stays warm and the seals are not stressed by temperature swings.
Vacuum & triple glazing
A hybrid GR85 pocket stacks an outer lite, an argon cavity, and a vacuum unit into 42 mm, approaching wall-level insulation without wall-level thickness.
Certification underway
NFRC and CSA testing is in progress. Until each label is issued, modeled values are shown as Calculated so the record stays honest.
