Every ANKA window and door starts with two decisions: the profile system that forms the frame, and the hardware that makes it open, close and lock. We build with multi-chamber, steel-reinforced uPVC profiles engineered to European standards, and we fit them with hardware from Roto, the German manufacturer that has specialized in window and door technology since 1935.
We manufacture right here in Calgary. That means we control the cutting, welding, reinforcing, glazing and hardware assembly of every unit, and we can deliver custom sizes with short lead times for homeowners, builders, architects and renovators across Canada.

The profile system decides how well a window insulates, how stiff it stays over large spans and how tightly it seals against wind and rain. The hardware decides how securely it locks, how easily it operates and how long it keeps doing both. Getting both right is what separates a premium European window from a standard one.


Our technology is built around two profile systems: Fens 7600 for European tilt and turn windows and hinged doors, and Easy Slide for sliding patio doors. Both are paired with Roto hardware and manufactured in our Calgary facility.
Steel-reinforced European profile for Energy-Efficieny
Fens 7600 is the 76 mm uPVC profile system behind our European tilt and turn windows. Its 76 mm system depth gives room for multiple insulating chambers, a deep glazing rebate and continuous seals between frame and sash. The result is a window that holds heat in, keeps drafts out and stays rigid in large sizes.
Slim sightlines and a sliding door that seals like a window
Easy Slide is our uPVC sliding patio door system, built around the Roto Patio Inowa hardware. Unlike a conventional slider that simply glides past a brush seal, an Easy Slide sash moves across the frame as it closes and presses into its gasket. That closing action gives a sliding patio door the kind of air, water and noise sealing usually found on hinged doors.
