Full-height doors as well as floor-to-ceiling windows have been a go-to choice for leading modernist architects like Ludwig Mies Van der Rohe. Flush interior doors with concealed door frames are the pinnacle of modern architecture in the United States, a trend pioneered in Europe.
We manufacture custom frameless doors as part of our exclusive door system which includes trimless pocket doors and flush recessed baseboards.
Each panel is a 5-ply (painted doors) or 7-ply (veneer door) solid core door sandwich. Engineered to support tall doors up to 137" without warping and to accommodate additional cladding and custom panelling.
The skin of the Dorsis door is an ultra smooth ¼" (6 mm) MDF board providing durable basis for high-end smooth finish – which you won't find in common dual MDF assembly solid core doors.
Each door slab we supply is using double-layer lightweight MDF boards to ensure both rock-solid stability for tall doors and excellent acoustic performance, so that you don't hear sounds.
Dorsis provides painted doors because site-painted doors never match the quality of factory finish. For most projects we use 20% gloss, with an option for high-gloss. We use 5-layer polyurethane-based paint process.
Your door slab will be easy to service thanks to the hidden door straightener. Should the door get out of plane, you can adjust the door straightener and bring the door back to being perfectly flush.
The entryway between the house and garage is usually the most used doors in the home. To make entry easy for all household members, we can optionally equip this door with an electronic or electromechanical lock, or a designer thumbturn.
A Dorsis concealed door with the Assa Abloy EL560 electromechanical mortise lock has handles on both sides: the outside handle is electrically controlled (by keypad, RDIF card or tag reader, or iPhone via a Bluetooth sensor), the inside handle opens the lock always.
Assa Abloy EL560 electro-mechanical mortise lock is designed to work with smart home automation systems such as Loxone or fingerprint scanner access systems such as ekey biometric systems.
Set up your Assa Abloy EL560 to unlock a locked door via the inside handle where the mortise lock pulls the long bolt back and also unlocks the flip latch (panic function). The lock locks automatically when the door closes (automatic locking).
For commercial applications, you can choose to equip the Dorsis Fortius door with a panic bar (such as HEWI Bar System 111/162) to allow free egress in case of emergency. The inside panic bar always operates and the outside handle is controlled and activated on signal from your access control system.
