The RAIS Visio 3 Three Sided UNIQ Inset Wood Burning Fire is a premium built-in fireplace designed around extra-large glazing, minimal visible structure and a wide three-sided view of the flames.
The UNIQ version is intended to make the appliance itself as visually discreet as possible. With glass across the front and both sides, the fire can be viewed from several angles, making it particularly effective in projecting chimney breasts, feature walls and architectural installations where a conventional front-facing insert would limit the view.
Its styling is deliberately restrained. The broad glass area creates an elegant frame around the fire without introducing heavy surrounds or excessive detailing, allowing the flames to become the dominant visual feature.
The door opens vertically by simply pushing the pane upwards, maintaining the clean appearance of the fireplace and avoiding the intrusion of a conventional hinged door into the room.
RAIS describes the combustion as quiet and capable of delivering comfortable, even warmth. The current manufacturer specification lists a rated heat output of 9.3kW, placing the Visio 3 UNIQ above many conventional residential inset fires and making it particularly suitable for larger living spaces, subject to an appropriate heat-loss assessment.
The supplied retailer information lists 78% efficiency and an A energy efficiency class. The product is also shown within DEFRA-exempt and Ecodesign categories in the supplied UK retailer information.
The fireplace incorporates the RAIS Advanced Glass Concept®, developed to create favourable conditions for keeping the glazing clearer and maintaining a strong view of the flames during normal operation.
With its combination of extra-large windows, three-sided glazing and minimalist architecture, the RAIS Visio 3 Three Sided UNIQ Inset Wood Burning Fire is designed for interiors where the fireplace should feel integrated into the building rather than added to it.

Expert Insight
The main attraction of the Visio 3 UNIQ is the relationship between the size of the glass and the amount of visible appliance structure. Its three large viewing panes allow the fire to dominate from several angles, making this model particularly effective where the fireplace is intended to form part of the room’s architecture rather than read as a conventional stove or insert.
Suitability
The RAIS Visio 3 Three Sided UNIQ Inset Wood Burning Fire is particularly suited to large contemporary living rooms, projecting chimney breasts, open-plan spaces and bespoke architectural fireplace installations where a powerful real wood fire with a wide multi-angle flame view is required.

The supplied RAIS technical extract confirms the 9.3kW rated output, but does not show full appliance, recess or outer-frame dimensions. These should therefore be taken directly from the current RAIS technical drawing before any construction work begins.
Final hearth construction, flue specification, air supply, structural requirements and combustible clearances should be confirmed against the current RAIS installation instructions and by the installer.
