The RAIS Visio 3 Three Sided Room Divider Inset Wood Burning Fire is a contemporary built-in fireplace with glass on three sides, designed to provide an expansive view of the flames while helping visually connect adjoining areas of the home.
With its increased depth and three-sided glazing, the RAIS Visio 3:1 is particularly effective when incorporated into a projecting chimney breast or room-dividing wall. Rather than restricting the fire to a conventional front-facing view, the flames can be appreciated from the front and both sides, allowing the fireplace to become a feature for more than one area of the room.
The design itself is deliberately understated. Narrow framing places the emphasis on the fire rather than the appliance, giving the Visio 3:1 a clean architectural appearance that works especially well within modern interiors and purpose-built fireplace installations.
Access to the combustion chamber is provided by a vertical sliding door, which opens by pushing the glass upwards. This avoids the intrusion of a conventional hinged door and helps maintain the clean lines of the installation.
RAIS states a rated heat output of 8.3kW, making the Visio 3:1 particularly appropriate for larger living areas and open-plan spaces, subject to the heat requirements of the property being correctly assessed.
RAIS also states 80% efficiency for the appliance. The technical specification separately lists a seasonal efficiency of 70%, which is a different measurement and should not be confused with the appliance efficiency figure.
The Visio 3:1 incorporates the RAIS Advanced Glass Concept®, developed to create favourable combustion conditions around the glazing and help maintain a clear view of the flames during normal use.
The supplied manufacturer information also displays DEFRA approval, making the Visio 3:1 relevant for UK installations where use in a Smoke Control Area may be required, subject to the exact appliance specification and installation conditions.
Combining a three-sided flame view, substantial output and minimal architectural styling, the RAIS Visio 3 Three Sided Room Divider Inset Wood Burning Fire is designed for spaces where the fireplace should become part of the architecture rather than simply an appliance installed against a wall.

Expert Insight
The Visio 3:1 is particularly useful where a conventional one-sided insert would restrict the fireplace to a single viewing position. Its three panes allow the fire to remain visible as you move around the room, making it well suited to a projecting chimney breast or partition that divides different living zones without completely separating them visually.
Suitability
The RAIS Visio 3 Three Sided Room Divider Inset Wood Burning Fire is particularly suited to open-plan living spaces, contemporary extensions, projecting chimney breasts and architectural room dividers where a substantial real wood fire needs to be visible from several directions.

Output specification note: some retailer material describes this appliance as a 10kW model, while the detailed RAIS manufacturer specification lists a rated output of 8.3kW. The 8.3kW manufacturer rating should therefore be used for the current product specification unless a different certified variant is being supplied.
The 80% appliance efficiency and 70% seasonal efficiency shown in the supplied RAIS information are separate figures and should not be presented as conflicting measurements.
Final recess dimensions, structural construction, hearth requirements, flue specification, ventilation and combustible clearances should be confirmed against the current RAIS installation manual and technical drawing before installation.
