The RAIS Visio 2 Double Sided Tunnel Inset Wood Burning Fire is a striking built-in fireplace designed to create a visual connection between two adjoining spaces. With glass on both sides, the flames can be viewed straight through the appliance, making it particularly effective when installed within a dividing wall between two rooms.
Its defining characteristic is the tunnel configuration. Rather than presenting the fire from only one side, the Visio 2 allows the flame to become part of both rooms simultaneously. This makes it especially well suited to open-plan interiors, adjoining living and dining spaces, and architectural partitions where the fireplace is intended to act as a shared focal point.
The design is deliberately minimal. Narrow framing and large clear glass panels keep the structure visually restrained, allowing the flames to dominate the view. RAIS describes the fire as being almost invisible once integrated into the wall, which is central to the character of the Visio range.
A vertical sliding door system provides access to the combustion chamber while maintaining the clean architectural appearance of the installation. The door movement is integrated into the structure, avoiding the need for a conventional hinged door projecting into the room.
The fire is fitted with a black-edged glass door as standard, while a stainless-steel edged version is available as an accessory. Optional cover frames can also be specified in either black or stainless steel to finish the junction between the appliance and surrounding wall.
The current technical information lists a rated heat output of 8.6kW, with an operating output range of approximately 5kW to 9kW and an efficiency of 80%. This gives the Visio 2 enough capacity for larger spaces while retaining the visual refinement expected from a premium architectural insert.
RAIS also uses its Advanced Glass Concept®, designed to create favourable conditions for a clearer view of the fire and help minimise soot deposits on the glass during normal operation.
The supplied manufacturer information displays HETAS and DEFRA markings, making the model particularly relevant to UK installations, subject to confirmation of the exact specification and certification of the appliance being supplied.
With its through-fire design, slim structure and architectural installation flexibility, the RAIS Visio 2 Double Sided Tunnel Inset Wood Burning Fire is a strong choice where one fireplace needs to serve two spaces without interrupting the visual connection between them.

Expert Insight
The main advantage of the Visio 2 is architectural rather than simply decorative. Installing the fire within a partition allows the same flame picture to be enjoyed from two separate rooms, while the minimal frame prevents the fireplace from visually closing off either space. This makes it particularly effective in layouts where designers want to define two areas while maintaining sightlines between them.
Suitability
The RAIS Visio 2 Double Sided Tunnel Inset Wood Burning Fire is particularly suited to open-plan homes, adjoining living and dining rooms, double-sided chimney breasts and architectural partition walls where a real wood fire is intended to be visible from both sides.

Output specification note: some retailer material describes this model as 10.3kW, while the detailed RAIS technical table and supporting specification supplied list a rated output of 8.6kW with a 5–9kW operating range. The current RAIS UK data sheet should therefore be treated as the final specification before publication or installation.
The supplied installation dimensions are presented as 788–444mm rather than a complete W-D-H set, so the current manufacturer drawing should be used when constructing the wall opening.
Final recess dimensions, structural support, hearth requirements, flue specification, ventilation and combustible clearances should be confirmed from the current RAIS installation instructions and by the installer.
