Details
Linear is our flagship uPVC window line, built on the Gealan Linear system engineered in Germany. It pairs a modern, squared-off sightline with the technical depth you’d expect from a passive-house-oriented profile: a 6-chamber, 74mm frame, three continuous gaskets, and support for glazing packages up to 50mm thick.
The result is a window that feels architectural rather than off-the-shelf — flat, angular frame faces with a matching interior glazing bead, available in a wide range of factory finishes from crisp White to Anthracite Grey and Black Smooth. Every unit ships with dual-function tilt-and-turn hardware and multi-point locking as standard, so daily ventilation and full-open cleaning access come built in.
Optional GEALAN STV structural bonding further stiffens the sash for larger formats, and an optional attachable nailing fin simplifies new-construction installs. Whether you’re specifying for a quiet, energy-conscious remodel or a full passive-house build, Linear is our go-to recommendation for the Pacific Northwest climate.
