The RAIS Visio 3 Three Sided Inset Wood Burning Fire is a contemporary built-in fireplace designed around an expansive three-sided view of the flames. Its minimalist construction, large glass area and discreet framing create an almost open-fire appearance while retaining the control and efficiency of a modern closed wood-burning appliance.
Glass extends across the front and both sides of the combustion chamber, allowing the fire to be viewed from multiple angles. This makes the Visio 3 particularly effective within a projecting chimney breast, feature wall or architectural fireplace structure where the flames need to remain visible from different parts of the room.
The appliance uses a rise-and-fall sliding door, allowing the glass to move vertically upwards when access to the combustion chamber is required. This avoids the need for a conventional hinged door and helps preserve the clean, integrated appearance of the installation.
The design is deliberately understated. A slim black or stainless-steel door frame can be specified, while an optional matching wide cover frame can be used where a more defined edge around the finished fireplace opening is preferred.
The supplied specification lists a rated output of 7kW, with an operating range of approximately 5–9kW. This makes the Visio 3 suitable for a broad range of larger residential spaces, subject to the heat requirements of the property being assessed correctly.
Efficiency is listed at 80%, while the appliance is also shown as Energy Class A. The supplied information identifies the model as DEFRA exempt, making it relevant for installations in UK Smoke Control Areas when installed and operated in accordance with the applicable approval conditions.
The RAIS Advanced Glass Concept® is designed to help create favourable combustion conditions around the glazing and support a clear view of the flames during normal operation.
With its combination of three-sided glazing, discreet framing and balanced heat output, the RAIS Visio 3 Three Sided Inset Wood Burning Fire is designed for projects where the fire itself should remain visually dominant.

Expert Insight
The Visio 3 is a strong choice where the fireplace needs to be visible from more than one direction without the greater scale of the Visio 3 L. Its three-sided glass configuration gives it much more visual presence than a conventional front-facing insert, while the 7kW rated output makes it more suitable for typical residential applications than some of the larger high-output models in the range.
Suitability
The RAIS Visio 3 Three Sided Inset Wood Burning Fire is particularly suited to contemporary living rooms, projecting chimney breasts, open-plan spaces and bespoke architectural fireplace installations where a three-sided view of a real wood fire is required.
