Insulated Glass Units
Sealed, certified, and consistent. IGUs engineered for thermal performance and manufactured at the volume window makers need.
The unit your windows are built around.
Every IGU we ship is assembled and sealed on our own lines in Guelph, then inspected before it leaves the floor. Whether you need a steady weekly supply for a production line or units for a single project, you get the same thing: consistent sightlines, clean seals, and glass that performs to spec.
For window and door manufacturers, consistency is the whole game. One out-of-spec unit can stall an entire line. That is why volume customers come to us and stay.

Insulated Glass FAQs
An IGU is two or more panes of glass separated by a spacer and sealed into a single unit, with the cavity filled with air or argon gas. The sealed airspace dramatically reduces heat transfer, which is what makes modern windows energy efficient.
