First Dorsis door installation in Boulder, Colorado

July 13, 2022

The doors have arrived! It is our first installation of Dorsis floor-to-ceiling interior doors in Boulder, Colorado. The house was designed by Brian Fuentes, the architect and founder of a local design-build firm Fuentesdesign, specializing in modernist residential architecture. Brian has become a well-known advocate of passive house design, and is one of the leading voices for building energy-efficient homes and promotes green home design at events across the United States.

Angelbau will install several full-height Dorsis Fortius 52 flush doors with concealed door frames for bedrooms, a trimless full height Belport pocket door for a guest bathroom, and a fire-rated flush-with-the-wall Fortius EI30 door, which will connect the house with the garage.

As is customary with all Angelbau deliveries, the client will get a complete ready-to-install door unit which is pre-finished and includes all of the hardware. In this case, the client went with the M&T Maximal door handles which are designed to hold a matching insert (plate). Since the doors are white, the inserts in the door handles are also white.

Here are a few pictures from the door installation. The installation was done by Zach Whitt from Front Range Fenestration.

This precision-cut door frame spreader bar is there during the installation to ensure a precise distance between the two concealed door jambs. Notice that the Hilti low-expansion foam has been trimmed to allow for drywall to slide cleanly right to the concealed door jamb.
