The RAIS Visio 3 Three Sided Room Divider UNIQ Inset Wood Burning Fire is a premium architectural fireplace designed to provide an expansive view of the flames from three sides while keeping visible framing to an absolute minimum.
Developed specifically as a room-divider fire, the Visio 3:1 UNIQ allows the fireplace to sit within a projecting wall or partition so the flames can be enjoyed from several positions within the surrounding space. This makes it particularly effective between adjoining living areas, open-plan rooms or architectural zones where the fireplace is intended to divide the space physically without visually closing it off.
The defining feature of the UNIQ version is its exceptionally discreet construction. RAIS describes it as a room divider without visible frames, allowing the three glass surfaces and the fire itself to become the dominant visual elements. The result is a cleaner and more architectural appearance than a conventional framed insert.
The extended depth of the combustion chamber and glass on three sides create a much broader flame view than a standard front-facing inset fire. This allows the fire to be appreciated from the front as well as both sides of the installation, making it particularly suitable for rooms where people approach or sit around the fireplace from different directions.
Access to the combustion chamber is provided through an upward-opening vertical sliding door, preserving the clean lines of the installation and avoiding the intrusion of a conventional hinged door into the room.
The RAIS Advanced Glass Concept® is incorporated into the appliance, using glass and combustion design intended to create favourable conditions for maintaining a clearer view of the flames during operation.
The current RAIS technical information lists a rated output of 11.3kW, making the Visio 3:1 UNIQ a considerably more powerful option within the Visio family and particularly relevant to larger rooms and open-plan spaces.
With its combination of three-sided glazing, virtually frameless construction and substantial heat output, the RAIS Visio 3:1 UNIQ is designed for projects where the fireplace is intended to become an integral part of the architecture rather than simply an appliance positioned against a wall.

Expert Insight
The Visio 3:1 UNIQ differs from a conventional three-sided fire because the design places particular emphasis on eliminating visible framing. This gives the flames a much more open appearance and makes the fire especially effective as part of a purpose-built room divider, where it can be viewed from several areas without a heavy appliance frame interrupting the sightline.
Suitability
The RAIS Visio 3 Three Sided Room Divider UNIQ Inset Wood Burning Fire is particularly suited to large open-plan homes, architectural room dividers, contemporary extensions and adjoining living spaces where a real wood fire needs to be visible from multiple angles.

The supplied retailer information lists 76% efficiency in one specification field but also refers to 80% efficiency within the accompanying product description. The manufacturer material supplied here confirms the 11.3kW rated output but does not provide an efficiency figure in the visible technical table, so the current RAIS UK data sheet should be checked before publishing a definitive efficiency figure.
Exact appliance dimensions, recess dimensions, flue requirements, hearth construction, ventilation and combustible clearances are not provided in the supplied technical extract and should be taken from the current RAIS installation drawing and manual before construction begins.
Because this is a large 11.3kW room-divider appliance, the chimney system, air supply and heat requirements of the property should be assessed as part of the installation design.
