Unison combines over thirty years of millwork expertise with precise European machinery to produce exact windows and door connections that fit seamlessly into your new or existing structures.

Mullions are fixed to the frame with a wood-to-wood dovetail joint in order to effectively transfer loads and ensure stable, tight connections.

Frame corners joints are rabbetted, sealed with silicone and fixed with 2" stainless steel screws.

The main frames are constructed from a single slab wrapping continuously around the window providing consistent grain and finished color.

Sash corners are connected with a finger-jointed mitre, glue and stainless steel screws to prevent separation or leakage in even the harshest climates.

Sashes are milled with an outer lip, which overlaps the frame by ¼" in order to provide an initial climate barrier. The sash-to-jamb joint is further protected with an outer perimeter fin-seal on the sash, as well as a hollow-bulb weather-strip at the inner joint.
